Nike Free 5.0 Running Training Shoes for Women. Black with white color. I purchased and wore them quite a bit so in fair used condition. I normally wear a size 11 shoe and these are size 12 because I recommend sizing up. Natural motion: the defining feature of these running shoes is the flexible outsole with laser, cut, hexagonal grooves, allowing your foot to move, bend, and flex naturally. Support: the Shoes use Flywire technology, which is are strong, lightweight cables that loop through the laces to provide a secure, lockdown fit around the mid foot. Lightweight Design: renowned for being extremely light these shoes offer a second skin fit with a breathable mesh upper. Cushioning: the 5.O on the Nike “Free Scale” represents a midpoint between a completely barefoot experience (0.0) and a traditional, heavily cushioned running shoe (10.0).
