When that happens to your heels it is a symptom of something happening inside you. i.e. it is not an isolated incident of just your heels drying out.

And the heel is a BIG indicator of kidney issues. You may have heard of crystals in the kidneys….well those same crystals also form in the heels. What happens to your heel is an indicator of what is happening to your kidneys.

Massage yr feet with coconut oil. Or castor oil.

For the kidneys, drink lots of water everyday, like 2 liters, on top of anything else you drink. And/or do a kidney cleanse. A kidney cleanse just drinking a special herbal tea every day for a month.
