Nike React Element 55 Men's Shoe - Black Borrowing design lines from heritage Nike running shoes such as the Internationalist, the Nike React Element 55 Men's Shoe embraces history and pushes it into the future. Nike React foam delivers lightweight comfort, while rubber outsole pods and reflective details offer a cutting-edge look that begs for a reaction. Cool Comfort A textile and synthetic upper, elevated with a high sheen, provides a lightweight look and feel. Robust taping and zig-zag stitching wind along the back of the upper for a cool, deconstructed vibe. Plush, Resilient Cushioning Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. A soft sockliner wicks moisture and contours to your foot to further amplify shock absorption. Next-Level Traction Extending to the midsole, springy rubber nodules are strategically placed at the front and heel of the outsole to deliver great grip.
