The Free RN GS 'Obsidian' was created for grade school kids with a lightweight construction consisting of engineered mesh in a stealthy colorway agreeing with the shorter days of its November 2017 release. Flywire cables integrate with the laces for a lockdown fit without adding extra bulk. Under the foot, soft foam with diagonal outsole sipes encourage natural motion, delivering a barefoot-like sensation inspired by shoeless Stanford athletes training on the campus golf course.
