Nike Free 4.0 Flyknit Men Shoes for sale. Ultralight Support
The Flyknit bootie upper-a one-piece layer made entirely of polyester yarn-seamlessly integrates areas of stretch and structure, providing ultralight support and a contoured fit. Knit-in Flywire cables cradle the midfoot for added support where you need it most.
Ultimate Flexibility
New hexagonal flex grooves are hot-knife cut into the outsole, wrapping around the sidewall and integrating with the upper to enable more natural motion. Secondary hexagonal and horizontal cuts intersect the flex grooves for even greater flexibility.
