Optimize your outdoor performance. Building on the success and versatility of the KSO and KSO Trek, FiveFingers presents the TrekSport for outdoor enthusiasts. It's designed with rugged, high-performance materials to help maximize your outdoor experience. We've used abrasion-resistant Coconut Active Carbon in the upper for natural breathability, 4mm EVA in the midsole for plating protection, and we've added a lightly cleated 4mm Vibram® performance rubber outsole for extra traction on a variety of terrain.
KSO IS BEST FOR: Fitness, Running, Trekking, & Travel
