Nike Pegasus Trail 5 GORE-TEX The winterized Pegasus Trail 5 provides wet-weather protection for trail running. A waterproof GORE-TEX upper, an all-terrain outsole and reflective details help you comfortably take on the elements. Combined with an Air Zoom unit and a ReactX foam midsole, it gives you responsive cushioning for an energized ride. Key Features: Waterproof GORE-TEX upper and 3-D print toe cap help keep water out so your feet stay dry. Nike Trail ATC outsole is made with 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 to prior React foam. The carbon footprint of ReactX is based on cradle-to-gate assessment reviewed by PRé Sustainability B.V and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered. Reflective detail on the side of the heel.
