The adidas NMD_R1 "Grey Black" delivers a subdued, neutral take on the lightweight lifestyle runner. The breathable knit upper features a dark grey finish on the vamp and heel, contrasted by a black quarter panel with grey three-stripe branding. A coated black Boost midsole, reinforced with matching black EVA plugs for added stability, rides on a durable grey rubber outsole to complete the simple two-tone aesthetic.
