Ultra-lightweight flexibility. The Nike Free Flyknit 4.0 running shoe continues the tradition of Flyknit with a woven upper that conforms to the foot for breathable, lightweight comfort with each stride. Flywire cables deliver support without extra weight, while the flexible Nike Free mid-sole/out-sole gives you natural range of motion over any distance.

A sleek, socklike fit perfects the featherweight design of a virtually seamless running shoe equipped with knit flywire cables for responsive performance support and hexagonal flex grooves for multi-directional agility. The revolutionary knit upper is built by a proprietary implement that creates little to no waste during production, so runners enjoy an efficient, eco-friendly fit.
