This is not the first time we've used sustainable materials in our collection. Over the past few years, we've used several materials in the construction of our sustainable shoes and accessories, including recycled metal, recycled knit, recycled nylon, recycled neoprene and recycled jersey, all of which are certified according to the Global Recycled Standard (GRS). Among many benefits, the use of such materials required fewer resources than that of new fibers and generated fewer CO2. They also diminished the environmental impact that come with garment waste. Additionally, we developed CleanStep, an exclusive technology that helps clean & filter polluted water using thermoplastic rubber derived from algae biomass.
