The adidas NMD_R1 "Gradient" is an impressive addition to the NMD_R1 collection. Done in black and white, the sneaker design is interesting with how it chooses to use the traditional colors. The upper is black and the branding and rubber heel enforcement are white. It's the gradient colored Three Stripes that switches things up, starting with white at the top and making its way to black at the bottom. The upper portion of the shoe is then supported by a full-length Boost cushioning midsole system, also following a gradient pattern from black up front to white by the heel.
