Vibram FiveFinger KSOs
The second installment in the FiveFingers lineup, The KSO (for “Keep Stuff Out”), is arguably one the most popular models to date. Though they feature a slightly thicker soles than the Classics and Sprints with the addition of a 2mm EVA footbed, these have been the go-to shoe since their introduction in 2008. With the introduction of a closed top and the security of a hook and loop strap, the KSO’s have been the most robust addition to the lineup.

- Runners
- Athletes
- Hikers (on milder terrain)
- People who want a minimalist casual shoe, but don’t care for the open-top design of the Classic
- Boaters/Watersport enthusiasts
You Shouldn’t Buy These FiveFingers If…
There’s not much your KSO’s can’t handle, but there are these few exceptions:
- You’re a hardcore hiker: As with the Classics and Sprints, the razor-siped soles don’t provide much traction on exceptionally muddy or rocky terrain.
- You live in more extreme or wet climates: The KSO’s take the weather better than the Classics or Sprints, but don’t insulate from heat/cold all that well. Also, if it’s wet out, so are your feet.
