How was the Mens Vibram Fivefingers TrekSport born? Some say Chuck Norris special ordered a pair of FiveFingers and this is what he recieved. That may be true but the best way to describe the TrekSport is to say they are the perfect marrige of the good looks of the regular KSO, the rugged performance of the Trek and the comfort of the popular Bikila. The TrekSport is carried on the back bone of the original Trek with its 4mm EVA midsole for plating protection and cleated 4mm Vibram performance rubber outsole for traction. The KSO heritage lives in the mesh upper and velcro strap. The Bikila's technology lies hidden unsuspectingly in the heel and toe with the achilles pad and reflective toes. All this comes in addition to the classic FiveFinger features: form fitting, hook and loop closure, and the name defining 5 toe design. The Mens Vibram FiveFingers TrekSport is the next evolution in the Fivefingers Legecy.
