The KSO is arguably our most successful FiveFinger to date, mainly due to its versatility. We added this back into the mix 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 Vibram XS Trek performance rubber soles are razor-siped for sure grip.

MEASURING & SIZING
Due to the unique design of Vibram FiveFingers, if you’re new to our shoes there’s a proven method to ensure you get the correct size.

Place a ruler or measuring tape
against a wall

Place your heel against the wall measuring the length of your foot.
Be sure to take the measurement of your longest foot and the longest toe (which is sometimes not your big toe).

Use the table below to find your correct size.
Note if you fall between sizes you should alway pick the larger size.
Picking the right size KSO EVO
This minimal design of the KSO EVO ultises a low stretch mesh upper combined with welded protective elements. If you already own a pair of five fingers, the EVO fit is slightly snugger than most. To achieve a relaxed fit we would suggest going to the next size up. To achieve a snugger performance fit stay at your size. If you have never worn FiveFingers before and are working off the sizing chart, if you are on or just over the matching size for your foot measurement we would recommend chooing the next size up.
