Run like you're barefoot in the revolutionary Nike Free 7.0 Runing Shoe for Men. This dynamic shoe helps you build extra foot and leg strength while you train. On the Nike Free 7.0 Running Shoe, synthetic lightweight mesh upper combined with overlays promises a comfortable, supportive fit, while a compression molded EVA midsole with Nike Free sipes provides advanced foot strengthening. Strategically placed BRS 1000 in outsole enhances durability. Studies suggest that barefoot runners develop stronger feet. Natural motion builds strength, and strength means speed. Deep cuts in the outsole mean your feet flex and move the way they would if you were barefoot.
