Launched in April 2009, the Air Yeezy ‘Zen’ was the first of three colorways that made up the first collaborative release from Kanye West and Nike. An overall new silhouette with details borrowed from the Nike archives, the design employs a mostly neutral colorway with vibrantly hued accents throughout. The patent leather midfoot strap comes in a unique texture while the toe cap features premium suede. Underfoot, the nondescript rubber outsole glows green in the dark.
