Transitioning from the chunky aesthetic of the 90s, Nike responded to the barefoot running trend by developing the OG Free model in 2004. The women's Free 5.0 Flash edition showcases a minimal sock liner in Hyper Punch, corresponding with the tongue and traditional lacing system for a pop of color. Offering a breathable, lightweight fit, the grey mesh upper includes synthetic construction to support multi-directional movement while a cushioned midsole below sits atop a flex-grooved rubber outsole.
