A smoother ride keeps you cushioned and comfortable across runs. The Nike React Miler 3 uses runner data across its design to help deliver a more comfortable running experience. The React midsole is crafted in a rocker shape, helping support feet, cushioning landings and smoothly transitioning to a responsive sensation when lifting feet off the ground. Data applied across the upper places engineered mesh in key zones for extra breathability. On the outsole it sees rubber placed in crucial zones to help deliver a smooth transition from heel to toe.
