The Pegasus Trail 5 provides wet-weather protection for trail running. A waterproof GORE-TEX upper, an all-terrain outsole and reflective design details help you comfortably take on the elements. With a ReactX foam midsole, it gives you responsive cushioning for an energised ride. This special design sends you to the South Kaibab Trail in the Grand Canyon, as part of our ongoing #IYKYK series. Waterproof GORE-TEX upper and 3D print toe cap help keep water out so your feet stay dry. The Nike Trail ATC outsole is made from an all-terrain compound that's great even in wet weather. Sturdy, high ankle cuff helps keep debris and trail rubble from entering your shoe. What's new? All-new ReactX foam midsole is 13% more responsive than previous React technology. Crafted for performance and planet, ReactX foam is engineered to reduce its carbon footprint by at least 43% in a pair of midsoles due to reduced manufacturing process energy compared with prior React foam. The carbon footprint of ReactX is based on cradle-to-gate assessment reviewed by PRé Sustainability B.V. and Intertek. Other midsole components such as airbags, plates or other foam formulations were not considered.
