The Womens Vibram Fivefingers TrekSport Sandals combines the warm weather comfort of a sandal with the barefoot performance you've come to expect from Fivefingers. The open window design of the synthetic upper keeps air flowing through the TrekSport Sandal for excellent comfort and breathability. Once you slip your foot into these Fivefingers sandals, cinch down on the speed lace system to lock your foot in. Don't worry about having to wear these too loose, as the padded tongue cushions against lacing pressure. Reflective surfaces on this upper aid in visibility in low light situations. Underneath the TrekSport Sandals is the same Trek sole as the original TrekSports, with cleated TC-1 Vibram performance rubber outsole for exceptional traction on a variety of surfaces. This sole makes these Fivefingers perfect for strolling down your favorite trail to catching a quick round of golf with your buddies. And sandwiched between the outsole and your foot is the TrekSport Sandal's 4mm EVA midsole which delivers plating protection against stones and other ground hazards. Breathable but protective, the Womens Vibram Fivefingers TrekSport Sandals are the perfect shoe for your weekend getaway.
