Cracked heels that are technically labeled heel fissures never look good, might be a real nuisance but because they can sometimes lead to more severe issues if they are not treated you have to take them seriously. These are more common in all those who have dry skin, are overweight and wear shoes with an open heel. The simplest way to deal with cracked heels is just giving the feet additional attention by starting with a moisturizing cream on them at least twice a day to start with for the dry skin. Once a day after it has improved will most likely be adequate. Consider moisturizers or balms that have a thicker consistency. A lot of them include skin-softening agents, such as urea and salicylic acid which may help clear away dead skin cells.
In the event the cracked heels don't seem to be fixed with that regular use of the lotion, next see a podiatric doctor. They will remove the thicker dead skin and then if you make use of the cream habitually after that, then that should help maintain it manageable. You might give your feet a little bit more attention before you go to bed by soaking the feet for approximately 10 minutes in plain or soapy water. After drying the feet next lightly rub your heels with a foot file or something like that that will help get rid of the dry skin. Use a heavier, oil-based cream and then cover with a pair of thin cotton socks or silicone gel heel cup at bedtime to help the moisturizer work. Also try and address the risk factors for the cracked heels. Losing weight over the long term should help and try and steer clear of using shoes that are open in the heel region.
Most importantly, you should not neglect the dry cracked heels as you may develop deeper fissures in the dermis which in turn raise your chance of an infection. When the above self-care measures do not help, speak with your podiatrist concerning other treatments you could have.
