You catch a glimpse of your heels and notice the rough, split skin along the edges, maybe even a crack deep enough to sting when you walk. It is uncomfortable, sometimes a little embarrassing, and easy to ignore until it hurts. The good news: most cracked heels respond well to simple care you can do at home.
Cracked heels, known medically as heel fissures, are most often caused by dry skin. With the right moisturizer and a consistent routine, mild cases usually improve within a few weeks. Here is exactly how to heal them, and how to know when it is time to see a clinician.
What causes cracked heels?
Cracked heels happen when the skin on your heels becomes too dry and thick to flex with the pressure of standing and walking. As that skin loses its suppleness, it splits, forming the fissures you see and feel. According to DermNet NZ, dry skin (xerosis) is by far the most common cause, and deep fissures can be painful to stand on and may even bleed.
Several everyday factors make cracking more likely. The skin at the edge of the heel takes the most pressure, especially when extra weight or hard surfaces are involved.
- Dry skin (xerosis), the underlying cause in most cases
- Carrying extra weight, which increases pressure and causes the heel fat pad to spread outward
- Standing for long hours on hard floors
- Open-backed shoes and sandals that let the heel skin expand and dry out
- Thickened skin or calluses (hyperkeratosis) that build up and crack
How to heal cracked heels at home
The cornerstone of treatment is simple: moisturize regularly. The American Academy of Dermatology recommends a heel cream containing 10 to 25 percent urea, applied right after bathing for the best absorption. In mild cases, moisturizing two to three times per day can resolve the cracking on its own.
Urea is the workhorse ingredient here. At concentrations above 10 percent, it acts as both a humectant (drawing in moisture) and a keratolytic (softening and removing hard, dead skin). DermNet NZ notes that 10 percent urea cream is the most commonly used product, with 25 percent reserved for severe fissures. Other helpful ingredients include lactic acid, alpha hydroxy acid, salicylic acid, glycerin, ceramides, lanolin, and petroleum jelly.
Mayo Clinic recommends an overnight routine that can speed things along: soak your feet for about 10 minutes, pat dry, gently exfoliate the thickened skin with a loofah or foot scrubber, then apply a heavy oil-based cream or petroleum jelly and slip on thin cotton socks to lock in moisture while you sleep.
- Moisturize at least twice a day, ideally right after a bath or shower
- Use a cream with 10 to 25 percent urea for thickened, cracked skin
- Gently smooth calluses with a pumice stone, loofah, or foot scrubber (don't overdo it)
- At night, apply petroleum jelly or a thick ointment, then cover with cotton socks
- Choose ointments over lighter creams, since they seal in more moisture
How long do cracked heels take to heal?
With consistent care, mild cracked heels often improve within a few weeks. The AAD notes that in mild cases, simply moisturizing two to three times per day can resolve the cracking. Deeper, more painful fissures take longer and may need a stronger urea product or professional treatment.
Consistency matters more than any single product. The skin on your heels rebuilds slowly, so daily moisturizing, even after things look better, helps prevent the cracks from returning. Urea-based keratolytic creams in the 10 to 20 percent range have shown efficacy rates of roughly 60 to 94 percent in clinical trials for heel fissures, which is why they are a dermatology staple.
How to keep cracked heels from coming back
Healing the cracks is only half the job. Keeping the skin soft and protected is what stops them from returning. Build moisturizing into your daily routine the way you would brushing your teeth, and pay attention to the pressure your heels take each day.
A few habits make a real difference over time.
- Keep moisturizing daily, even once the skin looks healed
- Wear closed, supportive shoes instead of open-backed sandals when possible
- Avoid standing barefoot on hard floors for long stretches
- Use a pumice stone or foot file regularly to keep calluses thin
- Stay hydrated and avoid long, very hot showers that strip the skin
When to see a doctor about cracked heels
Most cracked heels are a cosmetic and comfort issue you can manage at home. But some warrant professional care. The AAD and Mayo Clinic advise seeing a board-certified dermatologist or clinician if your cracks are severe, painful, bleeding, or simply not improving with self-care.
Diabetes raises the stakes considerably. A 2012 study of people with diabetes found that superficial foot and heel fissures had a prevalence of 9.0 percent and deep fissures 3.8 percent, with deep fissures linked to both nerve damage (autonomic neuropathy) and impaired circulation (angiopathy), raising the risk of infection and ulceration. If you have diabetes, reduced sensation in your feet, or any sign of infection, do not wait it out, get checked promptly.
- Cracks that are deep, painful, or bleeding
- Heels that fail to improve after a few weeks of consistent care
- Redness, swelling, warmth, pus, or other signs of infection
- Diabetes, poor circulation, or numbness in your feet
