Supporting you through long runs, shorter training runs, and anything you can put them through, the Nike Air Zoom Structure 25 is a versatile shoe with a high stack of cushioning. A rocker shape to the midsole, and an Air Zoom unit offers a smooth transition through your stride, while a wider forefoot complements the wider base for stability, and comfort in one. A single layer mesh upper, and durable rubber sole offer breathable comfort and long-lasting traction.
