Allowing athletes to feel their run, the Nike Free silhouette has been a go-to training shoe since 2004. The updated women's 5.0 version brings added benefits to the barefoot feel including a flexible mesh upper with structural synthetic overlays for support. Lace-through Flywire cables are visible through the ventilation windows, providing a customized lockdown for extra miles. Keeping the motion-forward vibe going underfoot, flex grooves are implemented in the sturdy rubber outsole.
