Better Fit: This version of Flyknit has added stretch yarns for an even more snug, foot-hugging fit, especially in the heel.
Breathability: Inspired by the Flyknit Racer, the Flyknit design features more open knit on the sides to let air flow freely and keep feet cool.
Lightweight: The soft, lightweight sole mimics your foot's natural movement through its innovative pattern. It expands and contracts with every landing and push-off.
