Cracked heels that are technically termed heel fissures never look good, is usually a real nuisance but as they could in some cases lead to more severe problems if they are not dealt with you have to take them seriously. They are more common in those who have dry skin, are overweight and use shoes that have an open heel. The ideal way to deal with them is just giving the feet additional attention by beginning with a moisturizing ointment on them at least twice a day to start with for your dry skin. Once a day after it has improved will probably be enough. Seek out moisturizers or balms which have a thicker consistency. Some of them include skin-softening agents, for example urea and salicylic acid that can help clear away dead skin cells.
If the cracked heels don't seem to be helped by that frequent use of the ointment, next visit a podiatric physician. They will certainly remove the thicker dead skin and then if you apply the lotion routinely after that, then that ought to help ensure that is stays in check. You could also give your feet some additional attention before going to bed by soaking your feet for about 10 minutes in plain or soapy water. Just after drying the feet after that carefully rub your heels with a foot filer or something like that to help remove the dead skin. Use a heavier, oil-based lotion and then cover with a pair of thin cotton socks or silicone gel heel cup at bedtime to help the moisturizer work. In addition try and target the risk factors for the cracked heels. Losing weight in the long run can help and try and steer clear of wearing footwear that are open in the heel area.
Most importantly, do not neglect the dry cracked heels because you can develop deeper fissures in the skin that increase your potential for infection. In the event the above self-care methods tend not to help, discuss with your doctor concerning additional treatment methods you could have.
