Many times overly dry feet, especially cracked heels, are an issue of heredity. However, you can reduce these issues by moisturizing your feet in the morning and before bed. If possible, you should also wear socks to bed to allow the cream to work. You should also remove hardened skin with a pumice stone. Prior to using the pumice stone, be sure the skin has been softened somewhat by the moisturizer or by soaking your feet.
