The Nike Free was conceptualized for a barefoot-feel after designers witnessed Stanford athletes opting to train shoe-free. The Nike Free 5.0 GS 'Vivid Blue' is a kids' sized take that arrives with a lightweight mesh upper with synthetic paneling. Flywire cables integrate with the laces, both in tonal Vivid Blue, to provide added stability to the ride. Below, a Free sole unit is deeply cut to allow for natural flex.
