The adidas NMD_R1, first introduced in 2015, draws inspiration from technical outerwear and incorporates elements from past adidas models. This particular version, dubbed the 'Grey Red', revamps the knit upper by adding a relief of the Three-Stripes, along with tonal branding on the tongue and heel, and a two-tone pull tab. To enhance its striking appearance, a vibrant Shock Red EVA plug accents the design. Furthermore, the Boost midsole offers excellent responsiveness, while the hexagonally cut rubber outsole ensures natural flexibility.
