The Nike Free 5.0 EXT 'Medium Grey' offers a casual update to the brand's barefoot-inspired runner. This rendition features a Medium Grey mesh upper with suede paneling. A soft lining and visible Flywire cables add contrast in the brand's Cyber hue. The speckled, Cyber-colored Nike Free sole unit is made from lightweight Phylite, cut with strategically placed flex grooves to imitate a barefoot feel.
