The Nike Women’s Air Zoom Structure 24 Shoes Running Shoes are designed to provide a responsive and secure fit while you’re on the road. These shoes feature a crash pad under the heel for a cushioned and smooth transition from heel to toe, as well as an engineered mesh upper for durability. Additionally, the shoes have a softer and more durable lining around the heel and ankle, and a moulded heel that securely hugs your foot. The lace-up closure provides a snug and comfortable fit, while the Zoom Air unit in the forefoot offers responsive cushioning. The data from hundreds of runners was used to inform the crash pad placement at the heel and create a shoe that supports runners who tend to overpronate. The durable rubber sole is built for mileage and features grooves in the forefoot for flexibility and vertical grooves down the side for stability.
