Nike’s Free RN Motion technology was born in 2001, offering athletes the comfort of flexible cushioning. The Nike Free RN Motion FK 2017 Flyknit sneaker continues the legacy with updated design elements. Its upper is decorated in a tonal Binary Blue colorway, composed of foot-hugging Flyknit for flexible containment. The two-strap system across the midfoot provides additional support. A foam midsole and an auxetic outsole strengthen the flexible Free sole.
