The Nike Air Zoom Structure 18 improves upon its predecessor with a triple-density Dynamic Support midsole. A new firmer foam along the heel and medial midfoot helps reduce excessive pronation, while Dynamic Support technology uses lightweight wedged foam to support your foot, dramatically increasing stability without adding weight.
Nike Zoom Air cushioning in the forefoot delivers a crisp, quick ride. Embedded in the Zoom Air bag are tiny fibers that flex into power position on impact, launching your step and setting up your next one. The result: pure, explosive, unrelenting speed.
Engineered Mesh throughout the upper provides comfortable ventilation and support where you need it most. For added support, asymmetrical Dynamic Flywire wraps the midfoot to create a secure, glove-like fit.
