Another month, another super shoe. Hoka has been on the forefront when it comes to running shoe innovation. They have been pushing the market like no other brand in the last few years. Hokas uprising is closely connected to their maximum cushion approach balancing with the weightlessness of their product. Their latest release features the utter pinnacle of their recent collection – the long anticipated Rocket X2. The Rocket in its second edition is the brands leading road-racing shoe. Plainly aimed for marathon racing, the X2 has everything that all carbon super shoes these days obtain – a springy oversized midsole combined with a firm carbon plate – the magic combination for speed. Although weight typically is one of the strongholds for Hoka shoes, I was quite surprised to find out that the update to the Rocket X does also include a weight gain of 234 grams. One of the explanations could be that the stack height has been raised from 30 mm/25 mm to 36 mm/31 mm. Although running in the Rocket X2 did not feel clumsy and heavy though. While Hoka seems to rule the running shoe market, their top racing shoes have been lacking the magic somehow. One of the explanations for this is, that Hokas compression molded EVA foam, that is widespread with their training shoes, lacks the energy return that is needed for quicker running. The Rocket x2 is the first Hoka shoe to use the PEBA foam that most of the other shoe brands take for their top range carbon race shoes. Hoka listened and changed quite everything to the initial Rocket X model. With the arrangement of the new foam material and a remodeled carbon plate, this shoe has an amazing springboard feel. I was super thrilled to feel that amazing bounce that this shoe overs. A very powerful and race-oriented feeling of pure bounciness. Entertaining! Quite weirdly, the Rocket X2 doesn’t feel as “high” as some of the other carbon plated high stacked super shoes. It feels more like you’re in the shoe, other than on top of it. An experience some of the other shoes give to me and something that is very noticeable with this model. Consequently, this shoe feels exceptionally stable for its style. I sneaked some dry trails in during one of my jogs with this shoe and it felt positively bizarre to do that in such ease with such a road racing shoe. Although I used this shoe on trails, it is clearly a road racing shoe and should be used just for this. The outsole is very solid, offers a great grip on dry and wet roads and runs smooth on the track. The design is pretty much flat and that creates a smooth and comfortable ride. Its feels very stable and durable, also something that is not the norm for high end shoes nowadays. For some runners the missing padding on the heel section might be a problem. I’m used to it especially in the light high end racing shoes, but it is missing in this model. After some runs I figured out how to lace the shoe and it didn’t cause me any trouble at all, but It surely is a feature that can be improved in the next version. Although there are some downsides, the latest version of the Rocket X is an amazing and fast racing shoe. It’s a proper and well-constructed update to its predecessor. The shoe has an amazing support for speed and that makes this shoe a lot of fun and easy to run fast in. While additional weight might be a problem, it gets outweigh by the pure springiness that is exceptionally special and to me one of the best on the market right now. It is no surprise that all Hoka Elite athletes instantly switched to this model as soon as it was accessible. A shoe that now moves that distinct Hoka character into a real road racing Rocket ship.
The year kicks off with the public unveiling of the long awaited and profoundly teased Saucony Supershoe. Throughout the last few weeks this shoe could be spotted on the fast feet of US Elite Runners Jared Ward and just a couple of days ago as Parker Stinson amazed with a 4th place finish at a stacked Houston Marathon, his fastest ever. Perchance the all-new Endorphin Elite helped a little. Let’s get into the specifics and see what magic Saucony is distributing with their chief model. During the end of last year, early prototype images have been flocking the internet and the prominent hype sites. The unremitting contest for the next super shoe is real, and Saucony has lifted the high stacked top range marketplace with the vastly applauded Endorphin Pro 3 in the 2022 spell. Although Elite Athletes hackle brands to drive the development further and further in this top range hustle, Saucony devoted time and resources to surpass the needs of their elite athletes with this shoe. As stated above, Stinson and Ward have been quite crucial in the course of the making and development of this shoe. Saucony continues with its strong dedication to raw performance products. Right on time for their 125th birthday, Saucony reveals the shoe, that at this point of time, is the lightest, fastest and most energy efficient product they ever put on the market. The companies latest and peak rebound foam, PWRRUN is the base of the Endorphin Elite. Carbon is a significant share of every so-called super shoe. An innovative fork-shaped carbon plate is constructed to push runners forward and that is obvious and well placed in the Endorphin Elite. Precisely engineered with thoughtful toe-spring for a faster turnover and a positioned forefoot for a more adaptive ride. The sensation of snappiness and the feeling of forward drive is up to a new extreme, something I have never experienced in any other model in this category. It is a typical road racing outsole. Kept to a minimum and features a thin layer of tactically placed rubber that provides confidence inspiring-traction deprived of adding needless weight. To me, the upper has always been one of the strong points in Saucony shoes. And there is no difference in this one. Saucony calls it “Performance Knit Mesh”. It is a next-to-skin upper that snugs around the foot super nicely and is highly breathable. The inner feels like a sock and offers great shelter for the feet during the run. Whereas high stacked shoes sometimes can feel a bit insecure, I had the feeling that the inner construction helps to evade just this. I even tested some light trails and that wasn’t a big issue but assuredly not the footing that this shoe should be used for. Your foots POV – A shot that highlights the thin upper of this shoe. Very elastic but jet stable as the sites is protected by an added guard that keeps the foot in place. Particularly during high paced intervals a real game changer. The Endorphin Elite essentially features a combination of the energy efficient PWRRUN HG foam together with a newly designed carbon plate. Saucony calls this the Speedroll technology. It can be found in all the Endorphin models, but the Elite Version features the most aggressive available. The ‘Original Running Brand’, as Saucony calls itself, is making waves with this shoe. The vast sole with a 40 mm heel and a 32 mm forefoot (Heel-to-toe Offset: 8mm) is the base and combines the springy feeling with great padding. The Endorphin Elite is a first-class racing shoe and made for the marathon distance. After four years of development Saucony accomplished the aim for a top-class running shoe. Often marketing quotes sound self-assured and harsh but when Parker Stinson stated that this shoe is “a real game changer” some truth can be heard in his words. While I struggled a bit with the sizing in the Endorphin Pros, the Elite is true to size. I tested the shoe in a US13 and they were fitting flawlessly. The toe box gives plenty of room which I used to had problems with in other super carbon plates shoes in the past. Notwithstanding the generous fit, the lockdown of the foot is super good also down to a special padding in the heel section of this shoe. Generally speaking, this is a well composed shoe in regards to fitting. I never felt any compromises. The up-to-date performance model from Saucony comes with a fully new design approach and clearly sticks out in the Endorphin assortment. In addition this shoe the companies top line up features the Endorphin Pro, the kindly cushioned tempo trainer in the Endorphin Speed, the day to day workhorse that is the popular Endorphin Shift and the carbon-plated trail racing shoe that I have already been writing about, the Endorphin Edge. It is pretty apparent that this shoe is made for competing in its purest form. The Endorphin Elite is a performance shoe and should shine when race day is here. The farfetched spring-back paired with the direct notion, the negligeable design and geometry are a seamless blend to run fast on race day. And with the initial flashy green colorway (there is another one launching soon) on the lightweight knitted, mesh blend upper, all is set to run fast and aggressive.
Sauconys PWRRUN PB midsole foam is the base for one of the brands most popular running shoe lines named Endorphin. With an energy return of 88% PWRRUN PB is Saucony’s lightest and most responsive cushioning ever. The foam is one of the best I have tried in the last few months and was used generally on road shoes. It is tremendously springy, and amazingly sturdy. After the foam and the respective Endorphin line gained following all across the road running market, Waltham, Massachusetts based Saucony, takes this line of the beaten track and onto the trails. But it is not only the foam. Saucony delivers a mix of carbon with their PWRRUN PB and shapes capable mixture for all off-road desires. To my liking, Saucony continues to offer a roomy toe box once again and to my full satisfaction also adds little shielding on top of it. A feature that protected me and my size US13 feet quite some time while being out and about. A suitable toe protection is key and nicely crafted with the latest Endorphin Edge. As a lot of trail runners looking specifically into bigger toe boxes like seen in popular Topo and Altra models, it can also be found right here. Saucony has adapted quite a lot of features from the Endorphin Road running line. Even though the general fit is now true to size, the sensation of the shoe compared to the road version feels very alike and bids the same snug feeling and comfort. A well understood change is a suitable modification to the upper. Although some other brands choose to take their road upper for their trail versions, Saucony altered that around and made the upper more robust and better suited for rougher excursions. Still the air circulation and comfort remains. The lightweight mesh dynamically pulls wetness away from your foot, keeping you cool and dry. The word carbon joint with running shoe, draws a lot of attention. Although it is practically standard to have carbon plated road running shoes, it is still a novel feature beside the street. We can now witness an invasion of carbon equipped models which is long overdue. Since years trail shoes were equipped with rocker plates as a protection feature on rocky trails. Now companies combine the protection with performance. Saucony uses a MonoFlex carbon-fiber platter named Carbitex. It is managed as a 3-quarter plate design that delivers the bounce and spring but still keeps the suppleness on the trails. This explicit carbon plate shape is unique and not used in any other carbon model. Most of the times, one plate is used or various, compact plates. This Carbitex plate has a lobster claw split that allows flexion. Who doesn’t like a pleasant, subtle feature? Saucony appears to pay more and more attention towards their trail line. Also, with a simple lace cover on the front upper. I took the Endorphin Edge through more than a few proper sessions including our latest SwimRun excursion at the Ötillö competition in Cannes (more HERE). The thoughtless mixture of rocky, technical trails combined with sand and proper off-trail runs AKA bushwhacking should have been a proper challenge for the Endorphin Edge, but it wasn’t really. There is no perfect shoe for such a competition, also when you consider that there was a proper amount of basic and clean road running on the agenda. We decided not to take a road shoe and expected to suffer a bit with a sluggish performance on the road, but that wasn’t the case. The shoe works very well on the road but undoubtedly excels on the trail and offers a splendid grip. And it doesn’t soak a lot of water thanks to the upper as described above. The true heart and sole (by any means…) is the PWRRUN PB foam that’s used throughout the midsole. I quickly became a fan of the foam. It is very durable and keeps the springiness for a long time. Some of the other super foams seem to last only for a short while, something I haven’t experienced in the Saucony Endorphin Edge until now. With a measurement of 36 millimeters at the heel part and 30 millimeters at the forefoot, the shoe is not overly high in stack. Which can be quite comfortable and secure on the trails. It still offers proper cushion through the PWRRUN PB foam. Something that adds to the very well-rounded overall firmness and steadiness amid the rounded corners of the midsole and outsole. Sauconys very own outsole material goes by the name of PWRTRAC. It is an adhesive, sturdy rubber providing proper traction. The 4-millimeter lugs work fine and deliver real good grip on techy trail but struggle quite a bit with real deep mud. The ground feel is amazing, and the transitions feel super smooth and quick. A close up to highlight the outsole material and the well placed lugs of the Endorphin Edge. As with almost all carbon plated shoes the style and kick-back changes in this shoe with the speediness you choose. It is not as bouncy and springy as its road brothers and sisters, but it still delivers a very exceptional feeling for a trail shoe. A feature that makes this allrounder a proper challenger for trail races. With the huge toe box, this shoe is even ready to take on an ultra-effort. Maximum cushion on minimal weight – the Saucony Endorphin Edge weighs in at 268 grams in US13. That is pretty light when you consider the proper amount of cushion that this shoe offers. This was one of the first sensations that this shoe offered to me during the first runs. Today it is the sensation that I’m looking forward to when I lace up. These days I use this shoe for a wide range of runs as it is happy to take on the roads as well. A proper allrounder that doesn’t compromise in its natural habitat. The last few seasons have been rough on the trail side of things for Saucony. Although the road shoes last to perform to the peak standards, the trail part wasn’t really looked after. At least that was the impression I had. After the modernized versions of the Peregrine 11 & 12 have been hits, I also became a big fan of the Xodus Ultra. But the up-to-date adding to the trail range takes the level to new heights. The Saucony Endorphin Edge is a proper high end trail shoe that doesn’t shy back from hard work and rough milieu. Whereas I was sceptic towards an implementation of the Endorphin series into the trail collection, this shoe has proved me wrong. Though daily sessions are a lot of fun, this shoe displays its full potential when its raced.
Keller Sports as well as Keller X have been of great service to me in the last few years. A lot of selected attire easy and fast accessible. Particularly Keller X is a place where I hang out habitually. That has not changed much even though I moved from Germany to Sweden over 5 years ago as they offer their services with the same quality here and several other European countries. Keller Sports has been a great source to check and buy gear. Also, this time as Keller Sports gave me the chance to test and review the up-to-date and long-awaited trail hype, the Nike ZoomX Zegama. During the last 6 weeks I had the chance to put loads of miles on this shoe. Read on what I have to say.
If you’re enthusiastic about competitive and honest trail and mountain running the word “Zegama” will certainly spike your attention instantly. Located in the rugged self-governing region of the Basque Country, in the northern part of Spain, this 1.600 people town is the hallowed place for off road running. Just to simply get a slot into the Maratòn Alpina Zegama-Aizkorri is a dream for many. Tennis has Wimbledon, motor racing the Monaco Grand Prix and golf the Open Championship – mountain running has Zegama. To simply name a shoe after this competition is aiming for the uppermost and sets expectations as high as the Aizkorri peak. Slowly but surely Nike has teased their newest footwear release via social media. At the end of last year, I had the first glimpse to what later would become the ZoomX Zegama. In the quest for the up-to-the-minute Kipchoge vaporfly Erlkönig, even road running focused hype accounts picked up a trail running shoe that contained the celebrated ZoomX foam. But don’t get trapped in the ZoomX hype on this one. The Zegama does not come with a full ZoomX midsole as you might know it from the road models. To simply have a full ZoomX midsole would be too unstable on the trails. It’s the classic Nike carrier system SR02 that’s build around the ZoomX foam. After the Trail Version of the Pegasus, the Terra Kiger and the Wildhorse, the Zegama is the newest adding to the Nike trail running assortment. The Zegama improves into the arrangement with supplementary cushioning. The Wildhorse used to be the most cushioned shoe and that has changed now. Like the latest Terra Kiger version, the Zegama comes with a rock plate protection. The popular ZoomX foam is used for the very first time in a trail shoe and is placed across the midsole. The rural town of Zegama is start as well as finish to the notorious Zegama-Aizkorri Maratoia. Over the classic marathon distance of 42.195 kilometers, competitors must attack 5,472 meters height difference across rough and technical exciting topography. The competition is known for a brutal course but generally for its crazy and dedicated crowds that line up along the climbs. I had the chance to tow the line twice. Since then, I have an idea how it must feel to climb Alpe d Huez during the Tour de France. Click the Links to read my 2013 & 2014 blog posts. Throughout the last decade I had the chance to run in more than a few Nike trail models. The Pegasus Trail version used to be a reliable partner as it was a shoe that literally lasted forever. On a tight budget this was the model I ran almost entirely in training. Frequently Nike made efforts to extend their trail running actions and for me it was quite interesting to see that they now also release a completely new model to their collection. Something that hasn’t happened for a good while. In preceding Nike shoes, I have been in awe of the ZoomX foam, and it did not disappoint in the Zegama. Some people say that the carbon plate is the big game changer in running technology. But I cannot fully agree. To me the rapid progress of the foam performance is a real game changer and something that this shoe benefits a lot from. A bouncy yet direct feeling that was new to me in a Nike trail shoe. A pleasant and well needed feature for trail running is the integrated Ankle Gator. It sits tight but does not irritate the ankle. Main aim for this feature is to stop rocks and dirt from entering the shoe. A pleasant and well needed feature for trail running is the integrated Ankle Gator. It sits tight but does not irritate the ankle. Main aim for this feature is to stop rocks and dirt from entering the shoe. Also aids the general stability that this shoe provides. Its easy to see a merge of some of the other Nike trail shoes in the Zegama. The forefoot and midfoot sections are very similar to the Kiger, while the back section leads towards the design of the Wildhorse. Important in a trail shoe is stability and despite the proper stack height, this shoe provides a great safe feeling on the trail while still being very comfortable and sprightly. A new-fangled off-road shoe does also mean an innovative sole design and lug pattern. With 4 mm deep, the pattern design works well on all sorts of terrain that I undertook here. I usually have a tiny commute to hit my local trails. Then I face an exciting mixture of roots, rocks, and technical single trails. Particularly the forefoot portion of the Zegama is something that I could trust a 100% on during all my outings. But just like older Nike trail models, the quality of the grip gets worse in wet circumstances. A problem that has been communicated before and still seems to be an issue with this shoe. A closer look at the lugs and the pattern design If you are used to run in Nike shoes on the road, the Zegama wont surprise you much. The feeling is practically the same and the ZoomX translates nicely towards secure off-road running without loosing the nice bounciness and the great direct cushion. It’s the base that makes this shoe the best distance model in Nike assortment. The ride in the Zegama is springy and the wide platform aids to even stabilize the general approach of this shoe. It appears that the platform is a bit wider than the Kiger which I liked a lot. It is a pretty high stacked shoe at 37mm at the heel and 33mm at the forefoot so the wider approach assists the general safe performance on the trail. Subtle details can be found all around the Zegama. Overall Nike nailed the design on this one, in my opinion. Since a few years they seemed to have figured out how to market and brand the trail models in a nice inventive and inimitable way without loosing the general design approach in the footwear line. As this shoe can handle a lot of diverse ground, it quickly has developed into a reliable partner to me in the last few weeks. It is a lot of fun on the road but clearly performs best when used on non-paved milieu. By any means it is not a shoe that would execute to its utter best during the iconic Zegama marathon, but I would undoubtedly race it on lengthier and flatter trail distances. The Zegama is a flawless fusion between a comfortable training and race shoe with loads of opportunities on hand. Only downfall is the performance in the wet. Something that I hope will be updated in the next version.
The mix of diverse resources that are used to produce a shoe, often makes it problematic or even impossible to reprocess. The awareness of burning shoes after they have been used was one of the driving forces in Salomon’s footwear development squad when they set out to form a running shoe for the roads that could later be recycled and used for other goods. The first design concepts of the Index.01 looked simple, unique and promising. Finally, it was time to release the end product. The generous wedge of sole material is a nitrogen-infused, TPU-based foam named INFINIRIDE. The bottom unit of the Index.01 can be milled into small fragments and recycled as soon as the shoe has reached the end of its lifecycle. The sole is comfortable, not too soft and with the rocker geometry does a great job to improve a comfortable stride and swift toe-off. Setting a mark – generating a full recycle loop entails some more actions. For example, the most environmentally friendly homecoming of the castoff product. With the presentation of the Index.01, Salomon also announces a reappearance strategy were users must register under Salomon.com. They obtain a shipping label that enable to send the shoes to a nearby collection center – free of charge. To diminish transport volume, the shoes will be collected there and shipped in bulks back to France for Salomon to use in future products. The upper of the shoe is thin, breathable and comfortable. Comfort is a big thing with this shoe as there is basically nothing to complain about. No rubbing or pinching wherever at the heel or toe section. Salomon chose the use of recycled polyester, which in case of this shoe, originates from old plastic bottles. The plastic flasks are undone into polyester fibers, which prevents the bottles from landing on landfill or being incinerated. The Index.01 is the first creation out of the promising and exiting Play Minded Program. Salomon aims to take the full life circle of their product and tries to keep the impact on the environment as low as possible. It will be exited to see what’s next. A comprehensive look at the back part of the shoe highlighting the unusual designed silhouette of the gigantic white TPU sole. A meek but very substantial detail that this shoe has to offer is the plain performance. Overall, this is a no-nonsense shoe. The stride feels natural and there is no unusual stress to the body of any kind. It is a fantastic and reliable training shoe and the curved sole drives a good bit of speed into the stride without stressing too much. To guarantee a proper all-around recycling circle, simplicity is key. Primarily the Salomon engineers were targeting to use just only one material to reach their prime goal. Previous prototypes I had seen used only one material – thermoplastic polyurethane foam (TPU). Still this concept wasn’t strong enough, so a second material had to be added and the upper is now made from recycled polyester as described earlier. Like the midsole, the outsole is also made of the same TPU material. This is unlike many other brands that use rubber material for this part of the shoe. The durability of the Index.01 is not affected by this. Also because the heavy used parts of the sole are build extra rigid. Minor studs shape the design of the sole and the grip on road runs is faultless and I liked it a lot. Smooth and simple design is also put into the place at this part of the shoe. The design is simple and smooth and mirrors the approach Salomon has with this line. The white colorway will eventually be obliterated by where the user takes this shoe. In a quite a short time, I have become a vast admirer of this shoe. For me the Index.01 offers everything I enjoy in a day-to-day training shoe. Notwithstanding the weight, the shoe is fun to run in and quicker stuff is not a real problem. Would I race with it? Doubtless not. But everything in between is fine. The entire idea that is being the shoe ticks all my boxes and I love that Salomon takes this on so offensively and well thought out. Some companies have tried to tackle the environmental matters but no one in the way Salomon has. To me, the concept completely makes sense and I’m really looking forward seeing what else is next. Until then, I just go out for another loop in my Index.01.
Undoubtedly Puma is no stranger to the running game. One of their prime athltes was Ethiopian Abebe Bikila who won the marathon of the 1964 Olympics in Tokyo wearing a pair of Puma running shoes. Defending his title from Rome 1960, which he won without wearing any shoes. Having had a massive impact on the worldwide T&F scene with the likes of Linford Christie and legendary Wilson Kipketer, the company further increased their fanbase with the early signing of superstar Usain Bolt. When Puma signed Bolt in 2003, he was only 16 years old, but this deal certainly paid off. Although being a recognized brand within the sprint scene, the company seemed to have forgotten its roots that, besides football, lies within running. In the beginning of 2021 a lot of professional runners switched sponsors and Puma appeared behind the name of a lot of recognized distance runners. With the Nitro range the company seem to hit the scene with new and promising products. The Deviate range symbols Pumas homecoming to the serious performance side of running. The very first prototypes made a lot of noise within the scene and Puma marked their return to the market with their interpretation of a carbon-fiber plate road running shoe. In 1924 Rudolf and his brother Adolf “Adi” Dassler formed the so called “Dassler Brothers Shoe Factory”. When they split in 1948, Adi went on to develop his own brand named Adidas and Rudolf established a new company called Ruda. Ultimately he changed the companies name into Puma and introduced the well-known symbol and the characteristic “Formstrip” in 1958. Until today both companies are situated in the small Franconian town Herzogenaurach in Bavaria, Germany.Puma offers two high-end models. The Deviate Nitro that’s studied here and the Deviate Elite as the absolute top range model. The crucial alteration between these two shoes is the foam material. Back in the days, way before the carbon excitement, companies used EVA material as the attention was more on cushion then on rebound. Then the carbon-bouncy propaganda took over and nothing has been the same since. The so-called Pebax material is the new reference class for springy shoes. Every company does use somewhat comparable. So does Puma for the Elite Version. The Nitro instead has a TPE sole. The presentation of this sole paired with the carbon plate is incredible. The structure and the placement of the foam generates a tremendously comfortable and lively piece of equipment. The Deviate Nitro is well-cushioned and the toe-off is speedy and energetic as you stride forward. A very nice feature of the Deviate line is that there are specific models for women offered. These versions have slimmer heel sections, lower instep, and a carved arch for a specific fit. A feature that should be a standard by now. A feature that made the shoe very comfortable for me, was this little feature in the back of the heel section. These pads are meant to lock the foot in the shoe and avoid slipping. Typically I tie my shoes very loose and this really made a difference to me, especially when running a bit faster. The natural environment for this shoe is the road. And that’s what the so-called PumaGrip does best. A solid and sturdy rubber provides great traction on non-technical environment. I used this shoes also on lighter and dry trails and had no problems. Despite the tendency of other running brands to use other expert rubber companies for the outsole material, Puma decided to create their own. The result is a good mix of rubbers that create a great and solid feeling for the ground and a material that appears to last well. I have about 400 kilometers on my pairs and it is astonishing how less wear this shoe has. While I was training with the Deviate Nitro the last few weeks, some of my training buddies got curious and one of the most asked questions was if this shoe is a racing or training shoe. Until now, I do not really have an appropriate response to this question. The shoe is light, the shoe is speedy, direct on the ground it feels yet very comfortable. Would I race with it? I probably would. Until now I ran the Deviate Nitro during several trainings, from commute runs, long runs to track work and fartleks. I keep loving the shoe for it reliability during all these occasions. Pumas return to proper running shoes suprised me and it will be interesting to see where the brand goes from here.
Herzogenaurach’s three stripes company just released the state-of-the-art renovation of their popular UltraBOOST series. There is possibly no shoe in the assortment that feature so much of adidas’ soft and springy Boost material then this one. In addition to the iconic three lines, the material has been a trademark for adidas running shoes since its very first release in 2013. I had the chance to test one of the first pairs, the Adizero Adios Boost, back then. Check the Post if you are interested.
With the UltraBOOST series adidas has been surfing amid the so called “lifestyle” and “performance” segment. There are no two opinions about the look, that is for sure. Nonetheless we will concentrate on the performance part of things in this post. As mentioned earlier on, the boost material is a trademarked polymer exclusively used by adidas. Basically, it is a lot of small balls which are compressed and molded to protect the foot from the ground and it delivers a certain boost while toeing off during the running movement. The small balls contain of patented thermoplastic urethane. Adidas cooperated with the German chemical powerhouse BASF (Hello Steffen 😉) to create this material. Adidas did not hold back with the usage of the boost material. Particularly at the back end of the shoe. At first the Boost material was only known within the running scene, but when a certain Kanye Omari West was seen wearing a pair of UltraBOOST “Triple White” in 2015, the shoes went mainstream and not only boosted running strides but also sales. The three stripes are an iconic characteristic that defines Adidas. At first the brand added the stripes to its running shoes to make them sturdier. One of the initial T&F athletes to use the shoes with the stripes was legendary Jesse Owens in the 1936 Summer Olympics. By now, the stripes on the clover symbol represent Adidas focus on variety. Finnish brand Karhu and Adidas used to share the three stripes but Adi Dassler bought the rights in 1952.Comfort undoubtedly is a key feature with this shoe. The upper feels super pleasant and comfortable. The pattern on the side of the shoe make sure that enough stability is provided. I like the sock-like design and the wide flexible fit around the forefoot. The Ultraboost 21 upper is made from flexible Primeknit material and is only 1.9mm thick. Compared to a traditional upper, this really feels like a sock. The last 7 years, the Boost material was a stable when it comes to cushioning. Several models have proofed this. Notwithstanding the age, the material is still good and certainly does the trick when it comes to the padding part. The energy return was lacking in previous models and adidas successfully changed this with this model and the newly developed LEP Torsion System. The Torsion system is something that can been seen in older models but adidas changed it quite a bit and added the flexible TPU fork to increase the toe off. A new standard is the Continental rubber that is used on the outsole of the shoe. Its durable and grips pretty well. Two german tradional companies unite. Continental was founded in 1871 as a rubber producer and still is strong in this segment producing all kinds of tires and car equipment. It is no top-secret that the Ultraboost 21 is not the lightest shoe. With a weight of nearly 380 grams in my US13 model it is weighty for its standard. Nevertheless, it doesn’t feel super heavy or unsmooth while running. The feeling was normal and I never felt I have to invest more energy then I essentially got out of the shoe. According to adidas, the Boost foam in this shoe is now firmer. This should result 20% more responsiveness. A close up shot highlighting the Primeknit upper that is made of yarn from recycled plastic bottles. It looks like the heel is one gigantic portion of Boost foam with one major drop. With 10mm, it is not that huge at the end. The heel foam is wrinkled around the cup of the heel and produces a setup that allows the foot to sit securely inside the midsole. This is a major change to the previous version, the Ultraboost ST. To me the Ultraboost 21 is a daily milage grinder. I really treasure the fit and the padding it offers. I use this shoe on a daily basis to get the base miles in the tank. I like the fit the reliability of the boost material that certainly doesn’t disappoint. With the arrival of the Lightstrike and Lightstrike Pro material it will be exitng to see what the future holds for this modell range. Boost is the heaviest of the current three Adidas performance foams and it will be interesting to see how the brand develops or include these materials further.
Something that these days is part of the shoe business, is the rumor mill. Since months Alameda, California grounded outdoor powerhouse The North Face, was set to drop a carbon plated shoe. Well, it seems that all major shoe corporations are on the outlook to apprise their respective top range models with this technology. But suddenly it was a brand that is not necessarily known for its shoe building skills, that joined the hype. Since 1968 The North Face distribute and produce outdoor equipment. It all started with climbing gear and then grew into a brought variety of accessories, clothing and footwear. Personally, I have tested more than a few of their off-road running shoes in the past. Although their jackets, vests, caps and technical gear have been a stable in my wardrobe over the last decade, none of the shoes have majorly impressed me and it seems that technical clothing was more the focus then suitable footwear. Now they released a performance oriented trail running shoe that goes by the name of Flight Vectiv, merging a 3 D carbon fiber footplate, midsole rocker geometry and SurfaceCTRL grip into the first trail specific shoe using the prominet carbon technique. I had a chance to spot the Flight Vectiv last April as Spaniard and The North Face athlete Pau Capell wore the shoe throughout the 2020 version of the Fjällmaraton around Åre, Sweden where he came 2nd in the 100 kilometer distance. Pau was part of the development process of the Vectiv equipment range and mostly this shoe. TNFs VP of Global Footwear, Jean Marc Djian aimed high when the company took on this project. The company recognized that another try into the footwear market had to be an innovative and exciting. The Flight Vectiv is the top model of the novel TNF shoe assortment. It is the one shoe that contains full-length carbon plate combined with a rocker geometry. This combination is intended to upsurge the energy return and I was more than keen to see how this mix turned out in a shoe that is intended to be used off the road, a setting where the carbon technology is more to be seen in up-to-date shoe releases. On the picture above some details of the carbon plate are teased on the external. Even though the sock-like silhouette of the shoe looked like a pleasing feature, I was quite staggered how rigid it was to get into the shoe. The opening is rather small and that undoubtedly created some matters to me. As soon as you’ve entered the shoe, there is not a tense sensitivity. It just appears that the entering part of the shoe is pretty close-fitting. After a while I got used to it and know how to enter as the reinforced, breathable-knit upper is pretty strechable. Running this shoe throughout wintertime, I have the feeling that the body-hugging fitting also stops all sorts of muck to enter the inside. To me something that is very helpful particularly with the heavy use of salt and sand on the local streets. Frequently the small particles find a way to enter a shoe. Not so in this one. Generally the one piece upper that is elasticated and hugs your upper foot and ankle is super nice and fits around the foot like a glove. With the Flight Vectiv, The North Face planned a shoe for the longer and ultra-distances. The company paid attention to durable ingredients such as kevlar, polyamide and matryx materials that they also tested and used in other equipment. This time it seems that The North Face was able to familiarize their extensive knowledge from mountain equipment into footgear. The Flight Vectiv is an overall quality shoe that is very well made. Till now I spend somewhat over 100 kilometers in this shoe and I’m constantly surprised how it tackles different grounds and weather situations. The picture shows the 3D-molded heel counter for a better fit, another nice detail in a well build shoe with a quality finish. There were times when The North Face allowed their sponsored athletes to use different shoes and switch from their very own models to the ones that the competition offered. This has clearly changed now with the new shoe range. Several athletes have been smashing FKT’s last year. One of my favorite runs has been the record setting Grand Canyon R2R2R-alt FKT effort by TNF legends Mike Foote and Rob Krar. Check their video here. Time for these two to tackle some SwimRun competitions i guess. Without a doubt, the climax of this shoe must be the so-called 3D Vectiv plate. It offers momentum and in combination with the stability Rocker shape, the foot placement is optimized. The shoe is not super soft as many other carbon running shoes, but this is something that aims the runner while running on technical ground. At the start it feels like the shoe is rigid as it does not provide much flexibly, especially to the sites. Although it feels stable and the feel for the ground is certainly given. Officially The North Face labels the Vectiv technology as “revolutionary soling architecture.” Fundamentally what they are describing are the layers beneath the feet. These are all the different foams and treads that work together to deliver a cushioned, safe and springy sensation. Despite the fact there is a lot of advanced and new material that has been incorporated in this shoe, the outsole is known from previous models. Grip on wet and dry terrain has been the attention in the development procedure. If you expect a super aggressive and “deep” outsole, you will be dissatisfied. The lugs are well and smartly placed but come in with 3.5 mm which is not a standard in trail shoes. After some sketchy situations, the design and traction really grew on me. To me it is a great mix of traction and control. The lugs are places in proper distance and that means that snow, dirt, or whatever sticky stuff you encounter, will not get stuck. I try to break in shoes on the treadmill. Until now, this tradition has never been used with trail shoes. It was different with the Flight Vectiv. It certainly is a versatile sole. A detailed look at the outsole construction that protects the 6 mm toe-to-heel offset. This shoe facilitated 14 North Face sponsored athletes to set FKTs wearing different Vectiv prototypes during a nearly race free 2020. To me, the Flight Vectiv delivers a high level of comfort and proper cushioning that still allows to feel the ground but not the pounding. Combined with the securely sensation of the sock-fit paired with a minor, cushioned padding at the upper heel region, this shoe ensures thoroughgoing comfort and support. Throughout the punitive dark and slushy time of the year and now, when all the lovely white stuff is about to dissolve, this shoe has really gotten to me. It’s fun to run due to the pleasant and well thought cushion, the ground feeling is excellent and joint with a well-planned outsole, it generates a certain security during the cold season. I ran the shoe a lot on icy and wintry streets but also took it around the local, technical, trail system. I get to treasure a well thought out shoe that I never saw coming from The North Face. Having run plenty of carbon-based road running shoes, I really valued this innovative tactic and the way it was shifted into a running shoe aimed to hit he paths. It can be discussed if it makes sense to issue a trail shoe that has a white upper, but at the end I felt it was enjoyable that the daily run was able to produce the color line. A very philosophical slant to this debate, I know. Its some sort of a minimalistic approach, even from the design. Typically trail shoes do look a bit unlike. The Flight Vectiv seems more like a road shoe. Yet, I have the feeling the shoe will continue in my daily rotation for a bit longer.
Just fresh from the shelves comes an update to yet another Hoka classic – the Challenger ATR in the 6th version with a lovely Gore-Tex top-up. To me, the Challenger has been a go-to shoe, particularly throughout the spring and winter period. Changeable weather conditions enquire some multipurpose capacities. This model is a characteristic “door to trail” shoe and I have been using the prior three versions in the past couple of seasons. The most substantial difference with this model is the Gore-Tex upper. Gore-Tex is a waterproof, yet breathable material that can resist water even though it is able to let water vapor through. This will allow you to keep your feet nice and dry from the outside. Especially in the wet season this makes the difference. Different shoemakers are using Gore-Tex material but, in the past, I had some bad experience. Although you still want the water to stay external, you want a shoe to be breathable. After several tough and wetly off-road kilometers I can attest the Challenger a damn well use of the material. It is not too thick and consequently permits some sort of air circulation. The design of the outsole remains the same. From what I could find out after about 250 kilometer in the ATR 6, the performance and robustness is the same as it was in the preceding versions. As detailed earlier on, the sole performs on a wide vary of undergrounds but is not a specialist at one. If you expect a companion for technical trails, then this shoe should not be your choice. Although the ATR performs great on trail you will feel the lack of an aggressive outsole design, the more technical and demanding the terrain gets. The Gore-Tex version of the new Challenger ATR comes in a stylish black, yellow and red colorway. If you want to get your hands on the Gore-Text type then this is the only choice you have, at least in the male variety. There is also a really nice all black version of the ATR 6 around, but then again deprived of the distinct shield that Gore-Tex provides. Smooth operator – commonly I break in a pair of Challengers as soon as the weather turns bad and unpredictable. This shoe is game for whatsoever is coming along thru the worser part of the year, at least when you are based somewhere in the northern hemisphere. I also like that it is not exceedingly soft and offers a nice spring paired with a proper cushion. The development of the material that is now known as Gore-Tex was a happy accident, born partly of frustration by Bob Gore in 1969 and has since been used in several outdoor garments such a shoes, jackets and trousers. Some raw details: Heel height comes in with 31 mm and the forefoot is 26 mm high. This creates a 5 mm Heel-Toe Offset.The focus of this update was to provide a smoother feel and a softer, more comfortable upper. Hoka One One also modified the rocker’s design for an enhanced heel-toe transition within the 6th version of this shoe. The Stinson is Hoka One One’s max cushioned trail shoe, I would put the Challenger one step beneath this model. Personally, I like the volume of provided underfoot padding as this shoe, to me, is a daily trainer and mileage eater. Therefore, I think this is the right amount of cushioning without taking the ground feeling, especially off road, away. Inside look – While on the road, the midsole sends some nice return that pretty much surprised me. I strike with the middle and forefoot and this part of the shoe is well and proficiently designed to be reactive. Having experienced the earlier models of the Challenger ATR, there is no major update when it comes to feel and ride. The biggest change in the sixth version is the more flexible upper material made from secondhand yarn. It feels more stable and comfortable then the previous version. Also, the lacing has been restructured and adds to the steady approach of this shoe. The Challenger ATR 6 endures to build its legacy as an exceptional versatile training partner.
Another update Hoka One One fans were highly anticipating. I might not run as many trails as i used to do, but i do cherish my Torrent model that i had on rotation. I was intrigued when the news broke out that an update is about to happen. If you want to ping point one of the central updates, it has to be the upper. Hoka came up with a completely new engineered mesh upper, that is made out of recycled polyester fiber, that fits was better than the initial one. So what makes the Torrent so special in general? It is a pretty supportive, well-cushioned, and lightweight shoe made to run fast on unpaved footways. While the Hoka’s Speedgoat is probably the most known and liked trail shoe in the assortment, the Torrent is the slimmer and less bulky brother. The weight difference between the first Torrent model and the 2nd version is not really there on paper. But what is really obvious is that the new version feels lighter. Several weeks of running in the shoe, i have no idea what it is. I weighted both models and they are nearly identical in weight with 268 grams in US 13. If you ask me, there is no faster trail shoe in the Hoka One One assortment than the Torrent 2. I used it for several SwimRun sessions, off-road training sessions and a full trail marathon through a varied terrain in the north of Sweden. Im completely sold on the 2nd version of this shoe. A low-profile cushion construction makes sure that the foot is close to the ground. A pretty essential feature for technical trails. Despite the proper cushion is the material firmer to provide a more efficient kick from the ground thanks to the Profile midsole. The upper feels thick but comfortable and even though the material is a bit thicker, it is pretty breathable and created no issues for me. Plus it does not scratch off opens up during rougher runs. After a few weeks of rough use, the upper are still fine. A close up of the new upper and the toe box that is slightly tighter then the previous model. The new overlays wrap nicely across the forefoot and toe boxes for proper support and protection during challenging trail runs. They not only look good, they work amazingly fine. Detail – The forefoot section of the Torrent 2. To praise proper cushioning in a Hoka shoe is an understatement. The Torrent has plenty of cushioning in the midsole area and provides an amazing energy return. But it is by far the trail shoe with the least cushioning in the Hoka range. This makes it the absolute go-to trail racing shoe for me. A core element in a trail shoe is the outsole. The lugs of the Torrent are not overly deep but well placed. Mud and deep trails are not a massive problem but wet stones are not the best friend of the Torrent. Overall i liked the comfort and the reliability that the sole provides. An updated sole design make the Torrent 2 more comfortable than its predecessor. With a Lug depth of 4mm and a better placing of the lugs, Hoka did a great job. The marbled sticky rubber outsoles with its multidirectional lugs provide a grip that can face a lot of challenges. Besides all the technical features, the Torrent is a pretty good looking shoe i must say. The new Torrent in its natural habitat. Mud and dirt is what this shoe likes and where it feels home. A proper update the Torrent line that i cherished now during the last few weeks. A shoe that moves fast and gives a great feel for the trail combined with cushioning that saves the legs. A delicate combination on technical trails well executed.
