Nike Free 5.0

Nike Free 5.0 Version 3

Unlike conventional running shoes that limit your movement, the Nike Free 5.0 ($70 – $92) bends and flexes, offering a more natural foot strike. Its unique and innovative design improves balance, stride and posture by strengthening the feet and legs with the same natural range of motion experienced from running barefoot. The Nike Free 5.0 features a forefoot upper venting system, ultralight Phylite midsole and medial variable lacing system. [source]
