The KSO is arguably our most successful FiveFinger to date, mainly due to its versatility. We added this back into the mix a few years back to celebrate the rebirth of a legend. When you're scrambling up a rocky bluff or bounding along a riverbank, the last thing you want is gravel and grit seeping into your FiveFingers. So why not Keep Stuff Out! The KSO has a snug fit, one of our most minimal sole constructions for maximum ground feel, and a breathable, quick drying upper. The KSO also features a thin, abrasion resistant stretch polyamide and breathable stretch mesh that wraps your entire foot to do just that. A single hook-and-loop closure helps secure the fit. Non-Marking XS Trek performance rubber soles are razor-siped for sure grip.
Vibram ® XS TREK is a technical compound that allows great overall performance qualities, in particular flexibility and wet traction. Highly responsive to the various demands of life, XS TREK will carry you from the trail to the urban playground and even to indoor activities, due to its non- marking features.
