To heal cracked heels, moisturise at least twice daily and coat dry heel skin with petrolatum before bed. If the rim is thick and hard, a 10–25% urea cream can soften it. Protect a painful split with a liquid bandage. Don’t cut the callus or put keratolytic acids into an open crack. Reduce heel pressure with closed-back, well-fitting shoes. Most simple cases should show progress within two to four weeks. Bleeding, infection signs, diabetes, poor circulation or numb feet change the plan.
What works for cracked heels, ranked by evidence
Highest confidence goes to consistent moisturising, not a specific brand. It replaces water in dry outer skin and slows further water loss. Urea, lactic acid and salicylic acid can also loosen thick surface scale. That can make a hard heel more flexible, but stronger isn’t always better.
Parker, Scharfbillig and Jones reviewed 22 experimental studies for the Journal of Foot and Ankle Research in 2017. Urea appeared in 14 studies, making it the most researched active. The studies varied widely and were mostly poor to moderate in quality. The reviewers could not name one ingredient as clearly superior.
A later trial helps put the marketing into perspective. Parker and colleagues randomised 41 adults with simple foot dryness to 25% urea cream or a basic paraffin moisturiser for 28 days. Thirty-four finished the study. Both groups improved, with no statistically significant difference between them. It tested dry skin, not infected or deep wounds.
Moderate confidence goes to urea when thick callus is part of the problem. It isn’t the only choice, and price doesn’t prove better healing. Liquid bandage and footwear changes have less direct trial evidence, but each addresses a clear problem: protection or pressure.
Match the treatment to what you see
| What you see | Best next step | What it can change | Main limit |
|---|---|---|---|
| Dry, rough heel with fine surface lines | Use a thick, fragrance-free moisturiser at least twice daily. Add petrolatum before bed. | Raises surface hydration and reduces water loss. | It won’t remove a heavy callus quickly. |
| Hard, thick rim with shallow closed cracks | Choose one heel cream with 10–25% urea, an alpha hydroxy acid or salicylic acid. | Softens retained scale as it moisturises. | It may sting irritated skin. Keep it out of open fissures. |
| A clean, painful split without infection signs | Use a liquid bandage as labelled, then moisturise the surrounding heel. | Shields the split and reduces painful movement. | It protects the crack but doesn’t fix callus or pressure. |
| Cracks that return with sandals or long periods standing | Switch to supportive, closed-back shoes while the skin heals. | Limits sideways spread of the heel pad and repeated splitting. | Shoes won’t correct an inflammatory or fungal skin condition. |

A simple routine that covers moisture and pressure
Wash or soak your feet in warm water for no more than ten minutes. Use a mild, fragrance-free cleanser, then pat them dry.
Within five minutes, spread a thick moisturiser over the heel.
If the heel has a hard rim but no open wound, use one keratolytic product there. Follow its label. Don’t stack urea, salicylic acid and a foot peel.
If intact callus stays thick, gently rub the softened skin with a pumice stone or foot file. Stop before it feels tender. Never use a razor, blade or callus plane at home.
Before bed, apply petrolatum over dry heel skin and wear clean cotton socks. The socks mainly keep the ointment on your feet and off the sheets.
During the day, wear shoes that fit and hold the heel. Avoid barefoot walking and open-backed shoes until the cracks close.
The American Academy of Dermatology Association gave similar advice in 2022. It recommends short washing, moisturiser containing 10–25% urea or another keratolytic, petrolatum at night and liquid bandage over cracks. Mayo Clinic’s 2025 guidance also recommends gentle exfoliation after a short soak, followed by heavy cream or petrolatum. DermNet’s cracked-heel overview explains that a dry callused rim splits as pressure spreads the heel pad sideways.
If dry, reactive skin affects more than your feet, our guide to repairing a damaged skin barrier explains gentle cleansing and moisturising. Heel callus still needs its own pressure and exfoliation plan.
What the fissure trial actually found
Gin and colleagues’ 2017 trial enrolled 167 people with diabetes and a deep, open heel fissure. Participants used either a cream containing urea, glycerine and petrolatum or its placebo for four weeks.
Complete healing occurred in 46.3% using the test cream and 33.3% using placebo. That primary difference was not statistically significant. Yet only 6.4% using the cream still had a deep open fissure, versus 24.1% using placebo. Dryness and broader fissure scores also improved more with the test cream.
The result supports a combined moisturising formula, not urea alone. Its diabetic population also limits how far we can apply those numbers to everyone. Still, it gives a useful timescale: judge progress over weeks, not one night.
What won’t solve the whole problem
Petrolatum is good at reducing water loss, but it doesn’t thin a thick callus. A keratolytic can soften callus, but it doesn’t close a moving fissure by itself. A liquid bandage shields a split, but it doesn’t treat the dry rim around it. Shoes reduce mechanical strain, but they don’t treat psoriasis, eczema or athlete’s foot.
Aggressive removal is the common mistake. Cutting callus can create a deeper wound and a route for infection. Strong foot peels can also irritate already split skin. If you exfoliate, keep it gentle and only work on intact callus.
How long should cracked heels take to improve?
Use two weeks as an early checkpoint and four weeks as the main one. The fissure trial detected meaningful differences by two weeks, while the moisturiser trials assessed their main results at four weeks. Your crack’s depth, ongoing pressure and underlying cause can change that pace.
Take one clear photo before treatment, then another in the same light after two weeks. Look for shallower edges, less surrounding callus and less pain while standing. This is a simple progress check, not a medical assessment.
If the heel is clearly improving, continue until the skin is smooth and closed. Then maintain it with daily moisturiser and suitable shoes. If there’s little change after two to four weeks, a podiatrist or dermatologist can check the cause and remove thick callus safely.
When home care is the wrong next step
Get prompt medical advice for spreading redness, warmth, swelling, pus, fever or rapidly worsening pain. A bleeding crack also needs assessment if it is deep or won’t close.
If you have diabetes, reduced feeling or poor circulation, treat an open heel crack as a wound. Contact your diabetes foot team, podiatrist or clinician rather than filing it or experimenting with acids. Nerve damage can hide pain, while reduced blood flow can slow healing.
Book an assessment if the pattern looks unlike simple dryness. DermNet’s 2018 tinea pedis review describes fungus as often asymmetrical. It may cause itchy scale between the toes or across the sole. Eczema and psoriasis can look similar, so appearance alone cannot confirm the cause. Moisturiser won’t treat an infection.
