In the '80s, the science of sport and wearable technology were new concepts. The ZX running series adopted these ideas with a visibly technical design that became a hallmark of its style. These modern streetwear shoes recall the retro-tech look of the original ZX 500. They're made of a mix of suede and lightweight mesh. Staying true to the innovative ZX spirit, they're cushioned for modern comfort with Boost, adidas' most responsive cushioning.
