I used to have really badly cracked feet, especially around the heels. It was painful, and sometimes my feet would bleed. Then I had foot surgery and afterwards I had to wear orthotics/braces and orthopedic shoes all the time, with white cotton socks. i used to go barefoot almost all the time.
my foot doctor says going barefoot is one of the worst things you can do to your feet. now my feet are soft and pretty. it is amazing.
i seldom use any cream or lotion on them. it took several months, but it really did work.
