The Nike Free 2025 brings you miles of comfort with Flyknit that delivers even more zoned stretch and breathability than before. The outsole pattern adjusts to your every step for a dynamic ride, top to bottom. Benefits - Flyknit on upper delivers zoned stretch and support. Grooves on the sole allow for flexibility and let you move freely. Dual-density midsole provides flexible cushioning. Dynamic heel feels stretchy for a snug, adaptive fit. Texture under the toe and heel enhances traction in these high-abrasion zones.
