You put your feet through a lot with your intense runs, so show them some support with the Nike Men's Air Zoom Structure 18 Running Shoe. It features a triple density foam for increased stability along with ultra responsive, high speed cushioning to help you go faster, longer. A new firmer foam along the heel and medial midfoot prevents excessive pronation for reduced foot fatigue, while Dynamic Support technology uses lightweight wedged foam to support your foot, greatly enhancing stability without adding weight. Zoom Air cushioning absorbs impacts and rebounds back into position, launching you into your next step and creating a quick, crisp feel. The engineered mesh upper provides ventilation where you need it most to keep your feet cool, and the Dynamic Flywire wraps the midfoot to create a secure, glove like fit. Phylon and Cushlon foams are fused together in the outsole for lightweight traction and cushioning, and deep flex grooves allow a smooth stride.
