How to cure dry heels? i use all kinds of cream even 100% pure petroleum jelly vaseline?

Try doing : What your doing and then wrapping your foot in Saran wrap, putting on a sock before bed time. You may see a difference. If not try a high concentration urea cream ( over 40percent) works very well with feet. This used to be by rx, now some are not rx but may be easier to find with rx.

Crisco: Use a good hydrating cream such as cisco shortening and cover with Saran wrap before going to sleep. You can also use 40% urea cream.
