Getting rid of cracked heels comes down to two things: softening the thickened skin that’s already there and keeping it moisturized so it doesn’t crack again. Most cases resolve within a few weeks of consistent home care, though deep or bleeding fissures may need professional treatment. Here’s how to approach it at every stage.
Why Heels Crack in the First Place
The skin on your heels is naturally thicker than anywhere else on your body, and it bears your full weight with every step. When that skin dries out, it loses flexibility. Instead of stretching under pressure, it splits. Calluses make the problem worse because that extra layer of dead skin is rigid and resists bending, so cracks form along the edges of the heel where force is greatest.
Common triggers include walking barefoot or in open-backed shoes, standing for long hours, low humidity, hot showers, and aging (skin produces less oil over time). Less commonly, cracked heels signal an underlying condition like hypothyroidism, diabetes, or autoimmune disorders that reduce moisture production. Diabetes deserves special attention: nerve damage in the feet can shut down sweat glands, leaving the skin significantly drier than normal and more prone to fissures that heal slowly.
Remove Thickened Skin Safely
You can’t moisturize through a thick callus. The dead skin acts as a barrier, so the first step is thinning it down. There are two approaches: physical and chemical.
Pumice Stones and Foot Files
Soak your feet in warm water for 5 to 10 minutes first. This softens the dead skin so it comes off more easily and reduces the risk of tearing healthy tissue underneath. Wet the pumice stone (never use it dry) and rub in circular motions with light pressure for about 2 to 3 minutes per heel. Stop immediately if the skin feels sensitive or sore. You’re removing dead layers, not grinding down to fresh skin.
Once a week is enough for most people. Clean the stone after each use and boil it monthly to prevent bacteria from building up. Never share it with anyone else.
Chemical Exfoliants and Foot Peels
Chemical foot peels use acids (typically glycolic or lactic acid) to dissolve the bonds holding dead skin cells together. You apply the mixture to your feet, and five to seven days later the old skin sheds on its own, revealing softer skin underneath. These work well for widespread calluses and rough patches but aren’t appropriate for heels that are actively cracked or bleeding, since the acids will irritate open skin.
For a gentler ongoing approach, look for creams containing urea. Urea is the gold standard ingredient for cracked heels because it does double duty. At lower concentrations (10 to 20%), it pulls moisture into the skin. At higher concentrations (20 to 40%), it actively breaks apart the protein bonds in dead skin cells, loosening calluses so moisture can penetrate deeper. For most people with cracked heels, a cream in the 20 to 40% urea range is the sweet spot. If you have diabetes, stay in the 20 to 25% range to avoid over-exfoliating fragile skin, and avoid anything above 40%, which is intended for professional use only.
Lock in Moisture Overnight
The most effective time to treat cracked heels is right before bed. After filing or applying a urea cream, layer a thick occlusive moisturizer (petroleum jelly works perfectly) over your heels and pull on a pair of cotton socks. The petroleum jelly creates a physical seal that traps moisture against your skin and prevents it from evaporating. It also keeps the healing environment moist, which speeds up repair of cracked tissue.
This overnight routine sounds simple, but it’s the step that makes the biggest difference. A thin moisturizer applied in the morning evaporates within hours. A thick occlusive layer sealed under socks has all night to work. Most people notice softer, less painful heels within 3 to 5 days of doing this consistently, with significant improvement by 2 to 3 weeks.
Daily Habits That Prevent Recurrence
Cracked heels come back if you stop caring for them, so building a low-effort maintenance routine matters more than any one-time treatment.
- Moisturize daily. Apply a urea-based cream (10 to 20% for maintenance) or a thick moisturizer to your heels after showering, when skin absorbs it best.
- Limit barefoot walking. Going without shoes, especially on hard floors, increases pressure on the heel pad and accelerates callus formation.
- Choose supportive, closed-back shoes. Open-backed sandals and flip-flops let the fat pad under your heel spread sideways, which puts more stress on the skin edges where cracks form.
- File weekly. A quick 2-minute session with a pumice stone once a week keeps calluses from building back up.
- Stay hydrated. Chronically dry skin often reflects insufficient water intake, especially in dry climates or during winter.
When Cracked Heels Need Medical Attention
Shallow surface cracks that don’t bleed are a cosmetic and comfort issue you can handle at home. Deep fissures that bleed, ooze, or cause pain when you walk are a different situation. Open cracks create an entry point for bacteria, and heel infections can escalate quickly into cellulitis, a spreading skin infection that causes swelling, warmth, redness, and pain around the affected area.
Signs that a heel crack has become infected include increasing pain, pus, expanding redness, and fever or chills. A swollen, growing rash without fever warrants a visit to your doctor within 24 hours. If you develop a fever alongside a rapidly spreading rash, that’s an emergency.
People with diabetes should be especially cautious. Reduced sensation from neuropathy means you may not feel a crack worsening, and impaired circulation slows healing. If you have diabetes and notice any heel fissures, a podiatrist can safely debride the callus and recommend a treatment plan calibrated to your skin’s needs. Using a pumice stone or high-concentration urea cream without professional guidance carries a real risk of creating wounds that won’t heal easily.
What About Stubborn Cracks That Won’t Heal
If you’ve been consistent with moisturizing, filing, and overnight occlusion for 3 to 4 weeks and your heels aren’t improving, the cracks may be driven by something beyond dry skin. Hypothyroidism slows skin cell turnover and reduces oil production. Sjögren’s syndrome impairs moisture production throughout the body. Bone spurs in the heel can change how pressure distributes across the skin, creating persistent cracking in specific spots.
A podiatrist can evaluate whether the issue is purely skin-deep or structural. For severe calluses, professional debridement with specialized tools removes far more dead skin in one session than weeks of home filing. For fissures that keep reopening, medical-grade adhesive or liquid bandage products can hold the edges together while new skin grows in from underneath.
