Pure and simple style, refined. These juniors' adidas NMD_R1 shoes combine a grey pebble outsole pattern with a sleek knit upper. They're made with BOOST for instant comfort and incredible energy return. 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. adidas NMD R1 Junior
