Fissures are splits in the skin, most commonly seen on the heel. They occur when your feet are dry and become flaky and rough, causing the skin to split apart. Interestingly, fissures can also occur when your skin is too moist and not properly ventilated, because the excess moisture can lead to bacteria and fungus that weakens and cracks the skin.
Fissures are most common in patients who go barefoot or wear open shoes often, as well as those who do not properly dry their feet or who sweat excessively or wear improperly ventilated shoes.
Symptoms: Signs of fissures include hard, dry, and cracking skin, as well as thicker skin around the edges of the heel. If the fissures are severe, it can be painful to put weight on your heels.
Non-Surgical Treatments: The best approach for treating fissures depends on how they developed.
If your fissures are caused by dry skin, moisturizer and antibiotic ointment can help fissures to heal and also prevent infection. Wearing shoes that cover your heels can also prevent infection from developing. If your fissures are severe, your doctor might tape them and remove rough patches.
If your fissures are caused by moist skin, drying feet properly, wearing cotton socks with shoes, and using antifungal powders and lotions can help.
