Fruit of three years of research and with a circular design, the new high performance running shoes of Salomon are completely recyclable: the upper in recycled polyester can be used to create other fabrics, while the bottom in TPU – which together with the geometry of the shoe helps propel runners forward with a quick transition – is combined with virgin TPU and allows for the production of Salomon alpine ski boots.
