Building on the celebrated legacy of the NMD, the NMD S1 maintains the sock-like knit upper, accented by transparent mesh paneling. Thick textured laces lock down the upper while underfoot the eye-catching midsole explodes outward. With purple detailing, this chunky midsole shrouds an irresistibly comfy BOOST midsole, while a tan rubber outsole with trefoil lugs completes the look.
