Breaking new ground for both Nike Free and Flyknit technologies is the new Nike Free Hyperfeel releasing tomorrow. This natural extension of foot anatomy is the first Free-soled Flyknit offering paired with this new groove pattern, which appears to be outside of the traditional numbering system. The Hyperfeel is also the first Free shoe with LunarLon cushioning. All of this engineering in a barefoot runner lives up to the ‘Nature Amplified’ tagline, and both guys and gals will have two colorways to choose from at launch. Check out all the options below and grab your pair from Nike Running retailers on September 5th.
