Nike's Free RN Motion technology, which was first introduced in 2001, revolutionized the way athletes experience comfort by offering flexible cushioning. Building upon this innovative legacy, the Nike Free RN Motion FK 2017 Flyknit sneaker incorporates modern design elements. The upper of the shoe showcases a sleek tonal Binary Blue colorway, crafted from the foot-hugging Flyknit material that ensures flexible containment. Adding to its functionality, the shoe features a two-strap system across the midfoot to provide enhanced support. The foam midsole and auxetic outsole work seamlessly together to reinforce the flexible Free sole, amplifying its strength.
