Want the barefoot running experience without the rocks between your toes? The Women's Nike Free+ 3.0 V4 provides the supreme flexibility you need for your runs and offers the style you want for every day. After learning that Stanford athletes had been training barefoot on a university golf course, three of Nike's most innovative employees set out to develop a shoe that simulated bare feet. After eight years of studying the biomechanics of bare foot running, the Nike Free was born. At only 5.8 ounces (women's size 7), this shoe offers lightweight support, flexibility for a more natural stride, and a sock-like fit that hugs your foot. 11 bright color options allow you express your individual style. Which one will you choose?
