Living in an extremely arid climate, my heels have been taking a beating. I found a little jar of Blue Goo Cracked Heel ointment at Walmart with a main ingredients of Emu oil.
It's a very orange colored ointment and will stain sheets and such, so a little goes a long way! I apply it to my heels at bedtime and rub it in deeply. I'm pleaseed with how well it works.When I use it at night, my heels are noticably softer in the morning. Good stuff!
