I have part of this problem as well, though the itching only happens occasionally. Usually, it's just the dry skin. You're probably going to get a host of answers here. Frankly, I've never really tried to cure it, but I have heard that a colloidal silver spray works, but you have to spray your shoes, not just your feet. Taking oregano oil internally might help, as might pao d'arco, but it also might not. It hasn't for me.
