I have been wearing minimalist shoes for about 3 years now. I was unable to run before, but can now run reasonable distances (up to half marathon) usually off road. I now find any built up supportive shoe too uncomfortable for words! I personally don't particularly like five fingers. None have enough grip to use confidently off road in all conditions, they have to fit just so and if you have odd shaped feet like me they probably won't be comfortable. At the moment Vivo barefoot seem to work best for me. I wear Ra's to work, evos as an everyday shoe, and neo trails for running and waalking. In the winter I size up and wear knee length sealskins which keep me toasty warm. Living in the SW snow and ice is not an issue, but if I did go somewhere it was a possibility, I would try Kahtoola running crampons, which seem to work for Anton Krupricka, who runs in them in some pretty wild conditions!
