Nike Hyper Elite Gumbo All Star 2014 Dri-FIT fabric helps keep your feet dry and comfortable by wicking sweat away from your skin to the fabrics' surface, where it quickly evaporates. Dynamic arch support and thick ribbing provides a stabile, secure fit. Spandex adds stretch and compression throughout, and a left/right-specific design maximizes comfort. Multi-density cushioning on the heel and top of the foot adds comfort and durability in high-friction and high-impact zones. Fabric: Dri-FIT 70% polyester/24% nylon/4% cotton/2% spandexMachine wash
