Nike Free Trainer 3.0

Running barefoot is great, if you don’t mind risking rusty nails and jagged rocks. Otherwise, there’s Nike’s Free Trainer 3.0. These lightweight kicks (roughly 9 ounces) are as close to going shoeless as it gets, offering flexibility and breathability thanks to a polyurethane-reinforced mesh. Other features include a sock-like fit, low-profile Phylon midsole and flex grooves to provide the sole with extreme articulation.
