I just got my first pair of Vibram "Five Fingers" shoes over the weekend while perusing Rutabaga.  So far, they seem to be working rather good.  I would recommend against wearing them in any workplace that contains tripping or slipping hazards, though.  So waiters or waitresses, avoid wearing these shoes at work -- wait until your time off.
