Barefoot is (technically) without shoes, you are right. But for those wanting the "barefoot" experience, more and more running shoe makers are coming up with "barefoot" shoes, just enough coverage to protect your feet from the road I guess. Anyway, because I am reading Chirunning by Danny Dreyer right now, I cross referenced his name with barefoot running and got his opinion on the subject on his blog.
