Nike ZoomX foam delivers Nike Running’s greatest energy return yet, and NEXT% adds more ZoomX for responsive comfort on race day. VaporWeave material up top is an engineered woven mesh that’s light and breathable while giving a secure, comfortable fit. Updated laces loop through lightweight side sashes that eliminate the need for an arch band—helping to reduce shoe weight and relieve pressure on the top of your tendons. Full-length carbon fiber plate in the midsole helps prevent energy loss in toe bends. Wider toe area gives a roomier fit and helps engage forefoot muscles. Lengthwise flex grooves on outsole enhance multi-surface traction in a variety of weather conditions. The translucent grid pattern looks fast.
