Cracked heels which are clinically called heel fissures never ever look good, could be a real hassle but because they may in some cases result in more serious concerns if they are neglected you need to take them seriously. These are more common in individuals who have dry skin, are overweight and use footwear that have an open heel. The ideal way to address them is just giving your feet a bit more attention by starting with a moisturizing ointment on them at least twice a day to start with for the dry skin. Once a day after it has improved will probably be adequate. Consider moisturizers or ointments that have a thicker consistency. A lot of them consist of skin-softening agents, for example urea and salicylic acid which can help get rid of old skin debris.
If the cracked heels don't seem to be fixed with that frequent use of the cracked heel cream, next visit a foot doctor. They will certainly remove the thicker dead skin and then if you apply the lotion consistently after that, then that ought to help ensure that is stays under control. You might also give your feet additional attention before going to bed by soaking your feet for about 10 minutes in plain or soapy water. Just after drying the feet then carefully rub your heels with a foot file or something similar to help you take away the dry skin. Apply a heavier, oil-based cream after which cover with a pair of thin cotton socks or silicone gel heel cup at bedtime to help the moisturizing lotion work. In addition try and target the risk factors for the cracked heels. Reducing weight over the long term may help and try and avoid using footwear which are open in the heel area.
Most importantly, you should not ignore the dry cracked heels because you can develop deeper fissures in the skin which raise your potential for infection. If the above self-care measures really don't help, speak with your doctor about additional treatment methods you could have.
