Nike's mission is to take running shoes to a whole new performance level, which is why the brand asked runners what they want from their running shoes. The answer was unanimous: better cushioning, better energy return, lighter weight and high durability. Uniting these four qualities into a single material resulted in a revolutionary new cushioning foam: Nike React technology. This foam quickly reacts to every stride, guaranteeing a run more energised than ever. The material is also extremely light and its durability has been tested and proven by amateur and elite runners who, together, have covered over 25,000 km in React shoes.
