The Nike Air Zoom Structure 25 shoes are ideal for road and forest trail running. They provide a high level of stability on the inside of the foot thanks to pronation support that limits inward tilting of the foot. Designed for overpronation runners, this shoe remains very comfortable thanks to a liner that perfectly hugs the shape of your foot for custom support. The upper is made of lightweight, breathable woven mesh. So your feet stay cooler for longer. You also benefit from enhanced comfort thanks to the soft Cushlon 3.0 foam cushioning, lined with the Air Zoom unit. The forefoot area is a little wider to give your toes more room for your runs. What's more, the waffle rubber outsole gives you plenty of grip on any terrain, road or forest path. This is truly a shoe for all running distances, as stable as it is comfortable.
