The Vibram Five Fingers Men’s KSO Trek is a more rugged version of the 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.
KSO TREK IS BEST FOR: Light Trekking, Trail Running, & Travel.
A properly fit Vibram Five Fingers should fit like a glove. Each toe should be as close to the end of the pocket as possible without touching. The goal is to free your feet not to practice modern foot binding, leave that to the climbers.
Even though these shoes are sized in European sizes they are unlikely to match up with your boot size. Be sure to measure your feet!
How to Find Your Size:
- Stand with your heels flat against a flat wall
- Slide a ruler underneath each of your feet and measure from the tip of your longest toe to the wall
- Using the longer of the two measurements check out the sizing chart below to help find your size.
- You may not fit into Five Fingers footwear if the two measurements vary more than 1/6 of an inch or if your second toe is more than 1/6 of an inch longer than your big toe.
