Our feet is a magnificent piece of anatomy that shoes only hinder. I would walk around barefoot if it was socially acceptable. Vibrams are the next best thing.
Here is an excerpt from a website about running barefoot.
"
Why run WITH shoes?
Were you born with shoes?
Did you grow shoes on your feet as a response to running?
What makes you believe that shoes are necessary?
Were you created, or did you evolve, to run with shoes?
What a cruel trick God, or nature has played on us, if we are so helpless that we could not run until we invented shoes!
But, seriously folks, from the moment when you first stand, walk, or run barefoot, your bare soles are going to immediately, precisely, and emphatically feel the ground. This is going to have a profound effect on the way you choose to walk or run. For most people who have lived with their feet inside shoes for long periods of their lives, its going to result in walking or running more gently much, much more gently."
