This is your new running companion for days when the weather changes. Its flexible, lightweight design and responsive cushioning let you go from road to trail without stopping. A waterproof GORE-TEX layer and an ankle gaiter keep your feet dry so you're free to run through any puddles that come your way. The GORE-TEX layer on the upper prevents water from seeping into your shoes without sacrificing the comfort of the Peg Trail. Plus, updated materials around the ankle help keep water and debris out of the shoe. Less rubber along the outsole creates a smooth transition from road to trail while preserving the React midsole throughout. Plus, it wraps around the front of the shoe to provide additional durability. A generative traction pattern combined with rubber in the forefoot provides extra grip for technical trails while maintaining a smooth ride for the road. The Nike React technology is a lightweight, durable foam that provides a smooth, responsive ride. Its full-length design ensures stability when braving rocky terrain.
