Yeah, I know. Odd topic. I was wondering though how others walk barefoot. For some reason, when barefoot I'd always walk on the balls and toes, but not with the heel. Often, since I can spread all my toes, I'd be splay-footed for increased balance and traction. Gotta tell ya though, stubbing that little toe does cause one to see how much that lil critter contributes to balance.
I guess that habit of mine goes back to my childhood, since there was this patch of stickers between our house and the public swimming pool on the prison farm. Balls and toes tend to thicken up quicker from wearing shoes and not, like the heel. Howsoever, getting those tines stuck in the tender parts by the arch can be rather painful. Hence the balancing act. Not to mention that almost all mammals do the same thing. It's perspective that makes their hind legs look backwards.
