Because it’s sandal season, the foot condition is now front of mind, and I wanted to get to the, ahem, bottom of it. So, I reached out to a board-certified dermatologist for answers.
“The technical name for cracking heels and feet is called keratoderma,” explains Joshua Zeichner, MD, director of cosmetic and clinical research in the dermatology department at Mount Sinai Hospital in New York City. It's telltale sign is a thickening of the skin (typically on the soles or palms), and there are several things that can cause the condition.
If it starts happening during childhood, it’s often genetic, but as an adult, it could have more to do with your surroundings than your genes. “In some cases, people may develop it later in life as a result of hormonal changes or environmental stressors,” says Dr. Zeichner. However, chronic skin conditions can put you more at risk, too. “People may also develop dry, cracked heels in conditions like eczema and psoriasis,” Dr. Zeichner tells me.
While it's important to figure out what's causing your dry, cracked heels for future reference, once they're in a certain condition, you really only have a single path forward. “When the heels are cracked and peeling, it means that the skin barrier is disrupted, so the skin loses hydration, becomes inflamed, and is at an increased risk of developing infections," says Dr. Zeichner. “Good skin care can help minimize this or prevent it from developing in some cases."
More on that: The best way to deal is by keeping your heels clean and moisturized. Wash your feet with a gentle cleanser that'll knock out bacteria without stripping feet such as Dr. Bronners Pure Castile Liquid Soap ($18) and moisturize them with a lotion that includes ingredients such as colloidal oatmeal (AKA oatmeal suspended in aqua) such as Aveeno Daily Moisturizing Lotion ($8) —it’s popular in products made to soothe dry skin. As a final step, seal all of the skin-loving and moisture-boosting ingredients into your heels with a super-rich balm such as Honest Organic All Purpose Balm ($13), which helps to form an occlusive barrier so none of the good stuff can escape.
And should none of the above leave you well heeled? "Make sure to visit a board-certified dermatologist for professional treatment," advises Dr. Zeichner. They'll be able to help you put your best foot forward.
