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 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.
