Nike Free 3.0 v4 - Women's View All ColorsThe Nike Free 3.0 Women's Running Shoe is the closest to barefoot that Nike has offered to date. Designed for flexibility and foot strengthening, it also delivers the underfoot protection and traction of a shoe.
Fit:The Nike Free 3.0 has a full inner sleeve made of mesh for a sock-like fit that hugs the foot yet still allows for easy on and off. The seamless, composite upper features larger perforations for more flexibility where it's needed and smaller ones in areas that demand more support.
FlexibilityFlex grooves along the length and width of the midsole enhance flexibility and help maintain stability, while diagonal grooves through the arch enhance flexibility and help increase foot strength. The low-profile midsole doubles as an outsole, dramatically reducing overall shoe weight.
