For a cushioned, natural ride, meet the Nike Free 4.0 Flyknit Men's Running Shoe, the next generation of natural motion comfort. By removing the lateral seam, its one-piece upper conforms to your foot and moves with the integrated Flywire cables for an incredibly adaptive fit. Hexagonal flex grooves let your foot move naturally. Lower-profile cushioning and rounded heel encourage natural footstrike. Strong, lightweight Flyknit upper provides a contoured, supportive fit.
