The Nike Free RN Flyknit 2018 features a classic color combination on the innovative running shoe in women's sizing. The recrafted Free RN silhouette mimics the feeling of barefoot running while providing stellar protection for the foot. The sock-like fit is updated with more stretch, while the lightweight sole supports the foot's natural movement with a state-of-the-art auxetic tri-star pattern. Dressed with a lightweight Flyknit upper shaded in black, the side Swoosh makes its presence known in white.
