Sporty sock trainers by BOSS with structured-knit uppers and a lightweight EVA sole with a rubber bottom. Featuring subtle branding at the tongue, side panel and backtab, these trainers are detailed with elasticated and webbing accents. For our RESPONSIBLE products, we always use at least 60% more sustainable raw materials. This pair is partly made with REPREVE fibers. REPREVE is a leading branded fiber made from recycled materials including PET bottles. Billions of plastic bottles go into landfills every year, and REPREVE transforms them in yarns for a better tomorrow.
