You better believe bare feet are sexy. Both pictures on the right excite me to no end. The only way high heels turn me on is when they take 'em off!
I think Playboy magazine started the heel thing . It came out in 1953. I guess if you like high heels and own most of the industry everyone gets heels.
I've never understood the porn industry (not that I ever watch that kinda stuff) - the beautiful starlet is always nude with the exception of high heels. You're not truly naked unless you're feet are bare also. Bare feet all the way.
