Cracks in the skin around the heel may be both unpleasant and painful. This condition is because of the thick or dry skin, on and around the periphery of the heels. The skin on your feet is typically more dry and dehydrated compared to the skin elsewhere on the rest of the body probably since there are no sebaceous glands in the thicker skin on the bottom of the foot. For that reason, your skin around the heels could lose flexibility and resilience as a result of that insufficient moisture. Because of the pressures of being on the feet, that dried-out skin can begin to split and it can result in ugly, painful cracked heels which may occasionally bleed. There are a number of factors which increase the risk for this including higher loads, increased weight, unsuitable footwear (particularly footwear which are open at the back), inherited genes, unhygienic problems and poor self-care, as well as nutritional inadequacies.
To prevent cracked heels, always try to use well fitted enclosed footwear that allow your feet to breathe and avoid footwear which are open at the back. It is important to keep well hydrated by drinking at the very least two litres of water each day because that can help. Exfoliate the skin frequently and moisturise every day with a decent cream. When it is more serious, this should probably be done twice a day in the beginning. There are some suggestions that omega 3 and zinc nutritional supplements might help (however they do need to be used with the other treatment options and not on there own). It would also help to stay away from excessive exposure of the feet to water or damp conditions. It is important that you clean your feet with tepid to warm water as opposed to very hot water. If these types of approaches tend not to help, then see a expert podiatrist. They can remove the thicker callused skin and provide further advice on the way to self manage.
