I was afraid to order these online because I worried about them not fitting. I must have measured my feet on 5 occasions based on the directions on the Vibram Fivefingers website. I got the same result every time. When they arrived, I thought I'd never get them on. Since they cover the entire foot and wrap around the base of your ankle, it was quite a challenge. I actually was sweating like crazy and very frustrated. Once I got them on, I was in love. They are so comfy. The next time I put them on, I put some lotion on the heal of my foot.....this makes them go on quick and easy. The instructions on Vibram site for measuring for size worked out perfect for me.

Before buying these, I owned a pair of Fila Skeletoes 2.0. I love the Filas also. However, the Vibrams are much more attractive. The Vibrams feel like the same thickness when I am just walking around the house, but I noticed the difference when running. With the Vibrams, I can feel rocks and cracks on the ground. It is more of a "barefoot" running experience. I am not sure if I like the feel of running in my Filas or Vibrams better, but I wanted to note the difference.

I have a painful bunion on one foot. This makes running in ordinary running shoes extemely painful. There is no pain at all for me in these. There was no "breaking in" period with these shoes. I went for a run the first time in them (2 days after they arrived) and I got no rubbing or blisters on my feet. I wear them without socks. The toe area of my foot is quite wide and the back of my foot is average to narrow. I worried that the shoes may be too tight in the toe area, but they fit fine. The fabric stretches. These are amazing.
