Go the distance with cushy confidence in every step. Building on the foundation of its predecessor, this shoe expands on its laceless design by adding secure support that feels like it "disappears" on your foot. More foam means better cushioning, keeping you comfortable as you run. Smooth and Responsive Nike React technology delivers an extremely smooth ride. It provides support for the 3 phases of a runner's stride—flexibility at toe-off, a smooth ride at mid-stance and cushioning at contact.
