The Nike Pegasus Trail 4 GORE-TEX offers a supportive, yet springy feel that is perfect for road to trail adventures. The React midsole foam powers you forward, with a durable, lightweight, and responsive ride. An engineered mesh is perfected through runner informed data for a sturdy, yet breathable feel. An extra skin across the toes provides additional durability. An invisible fit GORE-TEX lining offers precipitation protection without sacrificing comfort. The outsole is also created with information from runners like you, to provide a generative traction pattern. This means you get targeted traction for stability over rocky trails, and a smooth ride over roads. Overlapping rubber on the forefoot adds durability.
