Reliable responsiveness and extra stability make the Nike Air Zoom Structure 24 the perfect everyday running shoes to hit your goals. Backed by data from hundreds of runners, the heel crash pad is engineered for smooth transitions from heel to toe. This same information is used for the mesh upper which deliver stretch and breathability in key zones. Your foot is kept stable through runs with the foam midsole and vertical grooves in the rubber outsole helping to prevent the foot from rolling when striking the ground. The Air Zoom unit delivers the responsiveness for a fun underfoot sensation.
