I was a skeptic about the whole barefoot shoe fad but once I tried these I was hooked. They are extremely comfortable for working out or just wearing around. I wear them whenever I do work on my car, wash it, do yard work, etc... Word of warning, your calf's will be crazy sore after the first few runs in these but you will get used to it after 3-4 runs. The sole is a bit thicker than vibram brand shoes so rocks/pebbles aren't really an issue.
