Bikila Vibram FiveFingers Review

Don't judge a shoe by its coveringVibram recommends that if you're new to running barefoot, you should gradually acclimate to the shoes.

I typically run three to five miles about three or four days a week. So, to acclimate, for the first week I cut my distance in half. After my first few runs, I noticed a few things. First, my lower calves were sore, a sign that I was exercising a slightly different muscle group. Second, my feet were a little bit tender.
