Still one of our most tested shoes, the Nike React Infinity 3 was engineered to help you pursue your running goals in comfort. A breathable upper helps your foot feel contained but flexible, while increased cushioning around the heel and ankle provide a supportive sensation. The unique rocker-shaped sole allows for a smooth, stable ride on long and short routes. A Secure, Breathable Flex Flyknit throughout the upper creates specific zones of breathability, flexibility and containment for a feel that is cool and secure without being restrictive. Flywire technology provides support through the midfoot. Smooth and Steady Nike React technology provides a soft, responsive sensation. Shaped like a rocker, the sole has been engineered to provide support during all 3 phases of a runner’s stride. It feels flexible when you push off the ground, has a smooth ride as your foot moves forward and cushioning for when your foot hits the ground. A wider bottom allows for more stability on contact. Cushioned Feel, Higher Stacks High-rise cushioning is placed directly under your foot so you're closer to the foam for a truly responsive experience.
