NMD takes running designs from the past and mixes them up with cutting-edge technologies from the present. The result? Ultimate comfort. Everything about the sleek design of these shoes has a purpose, from the foot-hugging upper and plush BOOST midsole to the 3-Stripes overlays and midsole plugs that add support. Wherever you go, every step feels like a good one. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic — reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
