Leather foot?

If someone (Not me) wanted really resistant foot, what to do?Leather foot?
Hang out barefoot alot. When I was a kid, I have some serious callouses built up on my feet from walking around barefooted adjectives the time.
It helps when it's resembling 100 degress outside. Your feet will burn at first (move promptly!) but after a while, they'll build up callouses. Beware, though, calloused feet are style of ugly (even by foot standards...)
Hope this help!
Just walk outside barefooted. It may hurt at first stepping on pebbles and the approaching but soon you will develop resistant feet.
