Vibram FiveFingers Men's Kso trek

Two factors stand out as distinguishing characteristics of the KSO Trek as compared to the standard KSO: the lugged sole, which includes 4mm EVA to protect against "stone-bruising," and the use of kangaroo leather as the main material. The Vibram Five Fingers Men’s KSO Trek is a more rugged version of our popular KSO. The kangaroo leather upper and sock liner feels soft against the foot, yet is strong and tear resistant, with outstanding breathability. A 4mm EVA midsole offers plating protection from stone bruising, and a lightly cleated 4mm Vibram performance rubber outsole delivers improved traction on trails and over more rugged terrain.
