Cracked heels are one of the most common foot complaints — and one of the most preventable. Whether yours are mildly rough or deeply fissured and painful, understanding why they develop is the first step to fixing them for good. Here’s everything you need to know about causes, treatments, and long-term prevention.
What Causes Cracked Heels?
Cracked heels form when the skin on the heel becomes dry, thickened, and loses its elasticity. Under the pressure of walking and standing, thick dry skin splits instead of flexing. Several factors accelerate this:
1. Dry Skin (Xerosis)
The skin on your heels has very few oil glands compared to other parts of your body, making it prone to dryness. Cold weather, low humidity, and long hot showers strip away what little natural moisture is there. Without regular moisturising, the skin dehydrates and thickens as a protective response.
2. Prolonged Standing
Standing for long periods — especially on hard floors — puts sustained pressure on the heel pad. This causes the fat pad beneath the heel to expand outward, pushing against already-thickened skin and causing it to crack. Workers who stand all day (nurses, teachers, retail staff) are disproportionately affected.
3. Open-Backed Footwear
Flip flops and open-backed sandals allow the heel fat pad to expand sideways more freely. Without a shoe back to support the pad, the edges of the heel bear more stress with each step, speeding up cracking.
4. Excess Weight
Higher body weight places greater pressure on the heel fat pad, amplifying the mechanical forces that cause cracking.
5. Medical Conditions
Several health conditions are strongly linked to cracked heels: diabetes (neuropathy reduces sweat gland function), hypothyroidism (reduces oil production), psoriasis and eczema (accelerate skin thickening), and flat feet (alter heel weight distribution).
6. Not Moisturising
This is the single most preventable cause. Heels need dedicated moisture — body lotion applied to the legs rarely reaches the heel in sufficient quantities. Without a foot-specific moisturising routine, heels will progressively thicken and crack over time.
Stages of Cracked Heels
- Stage 1 — Dry and flaky: Surface skin is rough, slightly yellowed. No cracks. Responds well to moisturising alone.
- Stage 2 — Callus formation: Skin has thickened. Requires callus removal plus moisturising.
- Stage 3 — Superficial cracks: Visible fissures appear. Generally painless. Requires mechanical removal and intensive moisture therapy.
- Stage 4 — Deep painful fissures: Cracks extend into living skin, may bleed. Infection risk increases. May need medical attention.
How to Treat Cracked Heels at Home
Step 1: Soak to Soften
Fill a foot basin with warm water and soak for 15–20 minutes. Add Epsom salts, apple cider vinegar (mild exfoliant and antifungal), or a commercial foot soak. Softened skin responds dramatically better to treatment than dry skin.
Step 2: Remove Thickened Skin
After soaking, pat your feet dry. Use an electric callus remover on the thickened, callused areas around the heel rim and heel pad. For full technique, see our guide on how to use an electric callus remover. Work in slow circular motions. Electric tools are significantly more effective than pumice stones for cracked heels — they maintain consistent speed and pressure and reach into contoured heel areas that stones miss.
Step 3: Apply a Urea-Based Heel Cream
Immediately after removing dead skin, apply a rich heel cream containing urea (25–40% for severe cases, 10–15% for maintenance). Urea is a keratolytic — it breaks down the protein bonds in thick skin and draws moisture deep into the skin. Apply generously, cover with cotton socks, and leave for 30–60 minutes or overnight.
Step 4: Seal Deep Cracks (Stages 3–4)
For deep, painful fissures, use a liquid bandage or medical-grade heel balm to seal the crack. This protects the area from pressure and bacteria while it heals. Apply after your moisturising routine, before putting on socks.
How Often to Treat
For active cracked heels: repeat the full soak-remove-moisturise routine every 2–3 days until smooth. For severely cracked, painful heels that don’t improve within 2 weeks, consult a podiatrist.
How to Prevent Cracked Heels Long-Term
- Moisturise every evening: Apply a thick foot cream nightly before bed — this single habit prevents most heel cracking.
- Use your callus remover weekly: A quick 2–3 minute session once or twice a week prevents thick skin from reaching the cracking stage.
- Wear supportive footwear: Limit open-backed sandals and barefoot walking on hard floors.
- Stay hydrated: Dehydrated skin loses elasticity and cracks more easily.
- Use a humidifier in winter: Indoor heating dramatically dries ambient air.
- Address underlying conditions: If you have diabetes or thyroid issues, consistent foot care becomes even more important.
When to See a Doctor
For a complete foot care routine that keeps cracked heels at bay, see our step-by-step at-home pedicure guide.
See a podiatrist if your cracked heels are bleeding, show signs of infection (redness, warmth, discharge), are too painful to walk on, don’t improve after 2–3 weeks of consistent home treatment, or occur alongside numbness or tingling.
Frequently Asked Questions
How quickly can cracked heels be fixed?
Mild cracked heels can show significant improvement within 3–7 days of consistent treatment. Deep fissures typically take 2–4 weeks to fully heal.
Does Vaseline help cracked heels?
Yes — petroleum jelly seals moisture into the skin effectively. It works best applied at night over a urea cream, covered with socks. On its own it moisturises well but combine it with a keratolytic for full results.
Can cracked heels come back after treatment?
Yes, without a maintenance routine. The key is shifting from treatment to prevention: nightly moisturising and weekly light exfoliation prevent the thickening that leads to cracks.
What’s the best product for cracked heels?
The best combination is a urea-based heel cream (25–40%) for active treatment, and a rich shea butter-based balm for nightly maintenance. An electric callus remover used 1–2 times per week prevents thickening between sessions.
