After suffering last summer running completely barefoot on sharp gravel, I decided to order a pair of Five Fingers KSO and try them out. I'm pleased to report that they are the greatest thing since sliced bread. Running in these things gives almost all the benefits of running completely barefoot without much of the pain.
I tried them out on the Turnagain Arm Trail a week or so ago before all the snow had melted. I found out quickly that they are not waterproof at all and running over snow and ice turned my toes numb in about a half mile.
Overall they worked great though and I've used them quite a few times since then. The Turnagain Arm Trail has a lot of roots and ankle twisting terrain so take it slow if you run here barefoot until your calves and ankles become stronger.
There are several models of Five Fingers and I went with the KSO which stands for Keep Stuff Out. Not exactly an original name but they do work fairly well keeping stuff out. I put a link below for the most popular model of Five Fingers but if you're in Alaska and you're running trails or doing some peak running you should consider the KSO.
If you do order some Five Fingers don't get them from Amazon. For some reason, probably because of the barefoot running popularity explosion they really jacked up the price. REI still has them for a reasonable price.
