There’s a war that has been going on under your feet whether you know about it or not. Nike and adidas—and, to a lesser extent, other sneaker brands—have been jockeying for the comfort of your soles. In response to adidas’ Boost, Nike is proud to present React, which is a material that will first be seen in the brand’s Nike Epic React Flyknit sneakers. Nike claims the new material is a “softer, springier, lighter, and more durable foam,” which means these new racers are perfect for pounding the pavement or hitting the gym. While we have no idea how they quantify it, Nike also says the new React cushioning is 10% bouncier than the Nike LunarEpic Low Flyknit 2. Tested by athletes, the sneakers are set to drop on February 22.
