Some simple solutions for cracked heels

1) I find the easiest way for cracked heels is while bathing daily rub your heels with a pumice stone. Then after bath, dry well, apply moisturizing lotion or coconut oil. If you're living in cold climate, wear your socks at once.

2) Another simple solution is take a big juicy lemon, squeeze the juice, don't throw away the peel. Put your heel on each empty half of the lemon peel, seeing that it covers the cracked place well. Put on your socks, after 30 minutes, remove the socks. The acid from the lemon would have removed the dead skin cells and soften the skin. Your feet will have a nice fresh lemon smell !
