The Nike React Pegasus Trail 4 GORE-TEX is a versatile running shoe designed for unpredictable weather. It features a waterproof GORE-TEX lining to keep feet dry and a lightweight, responsive Nike React foam midsole for comfort and energy return. The outsole is engineered with less rubber for smooth transitions between road and trail and includes a generative traction pattern for grip on technical surfaces. Additionally, the shoe often includes a collar gaiter design to help prevent debris, water, and snow from entering.
