Nike's Air Max Tailwind 4 '99 SP celebrates the running icon's 20th anniversary with a two-piece pack launched in November 2019. Nodding to its original look, this iteration is done in Sail-colored leather with a contrast neoprene collar, stitched underlays and commemorative embroidery on the tongue. 3M reflective accents flash under low light. A molded midsole with bursts of Max Air tech and a rubber Waffle outsole grant durable support.
