Women's NIKE® REACT INFINITY RUN FLYKNIT 3 :: Like running on air, your updated Women's Nike React Infinity Run Flyknit 3 running shoes feature more cushioning around the heel and ankle for a softer, smoother ride. Nike added Flyknit technology in the upper creating specific zones of breathability, flexibility and containment so your foot feels secure, while still free to move naturally. For even more support, the Flyknit 3 carries you through your route thanks to a wider bottom that offers enhanced stability each time you touch down.
