Technologies
-
Flyknit
The Nike Flyknit technology uses ultra-strong fibers to create lightweight pieces that provide targeted areas of support, elasticity, and breathability.
Nike React
Nike React cushioning provides extraordinary responsiveness. When your foot touches the ground, the foam responds to the impact of your step by returning to its shape. The more energy you put into your step, the greater the energy return will be.
