I have been using Vibram Five Fingers for the last 4 years. I have put ~500 miles on 2 sets. I do not walk or run for sport or exercise, I am just active. I have put ~15 miles on these shoes. I wear them on Friday, the weekends and after work. When Friday comes, it's like my feet sing! I hate dress shoes, and if I could would wear these or my FFers every day.

Vibram soles are the only soles that I cannot wear out. I can wear out just about any brands of shoe's outer sole in ~10 months, and the inner sole is compressed and deformed at ~6 months. If the Vibram Five Fingers are "Gloves" these are "Mittens" for your feet. I have plenty of room to move around in them, and they do not squeeze my feet in random places like most of the shoes.

I am now going to try out some of the Black Leather ones, see how well they do for some Business Casual shoe.
