the Women's Air VaporMax 2 Flyknit 'Work Blue' injects Nike's fall collection with sky-inspired color. Equipped for a lightweight feel and unlimited flexibility, this state-of-the-art runner strips away bulky overlays and uses a one-piece Flyknit upper to provide the foot with a natural range of motion. The Flywire cables that are integrated with the laces offer support, as do the fused synthetic skins at the heel and toe.
