Nike Structure 24 Men。The Nike Structure 24 has you ready to hit the road. We tested hundreds of runners to design the crash pad under your heel that creates a cushioned, smooth transition from heel to toe. Those insights also created an airy upper with breathability right where you need it. Cushioned responsiveness A Zoom Air unit in the forefoot offers responsive cushioning. Every step helps create energy return to help drive you forwards. It\'s combined with a foam midsole for a firm, yet smooth and stable feeling as your foot hits the ground. Backed by data Data from hundreds of runners helped inform the crash pad placement at the heel. It helps provide extra cushioning for heel-to-toe transitions, supporting runners that tend to overpronate. That info was also used to put cooling exactly where you need it on the upper. Flexible and tough The durable rubber sole is built for mileage. Grooves in the forefoot to create flexibility and vertical grooves down the side help create stability. Mesh is engineered for durability. Laces can be cinched down for a secure feel. A softer and more durable lining around the heel and ankle helps keep socks from bunching up when you run. Comfy tongue helps pad the laces. Moulded heel securely hugs your foot. Weight: Approx. 312g (men\'s size 9) Offset: 8mm (Forefoot: 19mm, Heel: 27mm) Color: White/Hyper Royal New in Box
