I can relate... the cracks in my heels are awful and it has been going on for years. I think warm weather makes it worse and it actually hurts to walk. I have tried all kinds of stuff. I did ask my dermatologist about this last month and she gave me a prescription for something call Aluvea. I think it is actually for eczema, but it is starting to work. She told me I can get rid of this, but it is going to take a long time. We'll see.
