Nike's most natural ride to date, the NikeLab Gyakusou Free RN Motion Flyknit 2017 Men's Running Shoe features a supportive, contouring Flyknit upper and a revolutionary new midsole pattern that allows the shoe to expand, flex and contract with your foot during every step—so you can move more freely than ever before. Rich hues inspired by Gyakusou's colour palette elevate this performance favourite.
