The Nike Free 3.0 v4 works like an extension of your foot. This ultra flexible shoe bends naturally with each step, while the thin but soft midsole offers a close feel for the ground. The Nanoply upper stretches and supports where needed, giving a sock-like feel, and allows the shoe to be worn sockless for an even more one-with-the-road experience.
