The Vibram Five Fingers KSO Trek is a more rugged version of the KSO.  The kangaroo leather upper is soft and luxurious against your bare feet, yet strong and tear resistant with amazing breathability.  These shoes are comfortable, functional and so stylish that many people wear them to work. 

The Trek has a 4mm EVA lugged outer sole which gives improved traction on trails and rugged terrain.  Despite this extra thickness and cleated sole you still get a great deal of ground feedback, making it a fantastic 'barefoot' shoe for outdoor wear.
