Cracked heels are a common foot-care problem in adults, especially when the skin around the heel becomes unusually dry, thick, and less flexible. Small cracks may initially look like a cosmetic concern, but deeper heel fissures can become painful, bleed, and potentially allow bacteria to enter the skin.
The good news is that most mild cracked heels can improve with consistent moisturizing, gentle skin care, appropriate footwear, and protection of the damaged skin. However, persistent or severe cracks may sometimes be associated with conditions such as athlete’s foot, eczema, psoriasis, diabetes, or hypothyroidism and may require medical evaluation.
What Are Cracked Heels?
Cracked heels, medically known as heel fissures, occur when the skin around the heel becomes dry, thickened, and less elastic. As the heel bears weight during standing and walking, the thickened skin can split and form visible cracks.
The problem often begins with a rough or hardened rim around the heel. Over time, continued pressure and dryness can cause these small fissures to become deeper and more painful.
Cracked heels can range from:
- Mild surface lines
- Rough, flaky heel skin
- Thick calluses
- Deep fissures
- Painful cracks that bleed
Common Causes of Cracked Heels in Adults
1. Very Dry Skin
Dry skin is one of the most common contributors to cracked heels. The heel area can become particularly dry because it has relatively little natural oil production compared with many other areas of the body.
Cold or dry weather, frequent washing, and prolonged exposure to water can further contribute to dryness.
2. Thick Calluses
When repeated pressure causes the skin around the heel to become thick and hardened, it may lose flexibility. Eventually, the rigid skin can split when the heel expands under body weight.
3. Open-Back Shoes
Flip-flops, backless sandals, and other footwear that does not adequately support the heel may contribute to cracking. These shoes can allow the heel area to spread outward during weight-bearing.
4. Long Periods of Standing
People who spend many hours standing, particularly on hard surfaces, place repeated pressure on their heels. This can encourage callus formation and increase the mechanical stress that contributes to fissures.
5. Hot or Long Showers
Long, hot showers and baths can remove some of the skin's natural oils and worsen dryness. The American Academy of Dermatology recommends limiting baths and showers to about 5–10 minutes and using gentle cleansing products.
6. Athlete's Foot
A fungal infection known as athlete's foot can cause dry, scaly, peeling skin and may sometimes affect the heels. If cracking is accompanied by itching, scaling, or peeling elsewhere on the foot, a fungal infection may be worth considering.
7. Eczema or Psoriasis
Certain inflammatory skin conditions can cause persistent dryness, scaling, thickening, or cracking. Eczema and psoriasis are among the conditions that can affect the feet and contribute to heel fissures.
8. Certain Medical Conditions
Persistent or unusually severe cracked heels can sometimes occur alongside conditions such as diabetes or hypothyroidism. People with diabetes need to be especially careful because reduced sensation or other foot complications can make injuries harder to notice and heal.
Symptoms of Cracked Heels
The symptoms can vary depending on how severe the condition is. Common signs include:
- Dry, rough heel skin
- Flaking or peeling
- Thickened skin or calluses
- White, gray, yellowish, or darker areas of hardened skin
- Fine lines or small cracks
- Deep fissures
- Heel tenderness
- Pain while standing or walking
- Bleeding from deeper cracks
When fissures become deep, normal activities such as walking or standing can become uncomfortable. Severe cracks may also provide an entry point for bacteria and increase the risk of infection.
How to Treat Cracked Heels at Home
For mild-to-moderate dry cracked heels, a consistent routine can make a significant difference.
1. Moisturize Regularly
Apply a thick moisturizer to your heels at least twice a day, particularly after bathing. The American Academy of Dermatology recommends products containing ingredients such as 10–25% urea, alpha hydroxy acids, or salicylic acid for dry, cracked heels.
These ingredients can help soften thickened skin while improving moisture retention.
2. Apply Petroleum Jelly at Night
Before going to bed, apply a layer of plain petroleum jelly to the heels. Wearing clean cotton socks afterward can help keep the product in place overnight.
3. Gently Remove Excess Dead Skin
After soaking the feet briefly in warm water, gently use a foot scrubber or pumice stone to remove some of the thickened dead skin.
Do not aggressively scrape the heel. Avoid razors, scissors, or cutting tools because removing too much skin can cause injury and infection. Professional debridement may be appropriate for severe callus buildup.
4. Protect Deep Cracks
A liquid bandage or appropriate protective dressing can help cover fissures, reduce discomfort, and create a barrier against external contaminants.
5. Choose Supportive Footwear
Avoid frequently wearing worn-out shoes or footwear that leaves the heel exposed. Properly fitting shoes can help reduce excessive pressure and friction around the heel.
6. Keep a Consistent Foot-Care Routine
Treating cracked heels once or twice is often not enough. Continue moisturizing regularly even after the skin looks better to help prevent the problem from returning.
What Ingredients Help Cracked Heels?
When choosing a heel cream, look for ingredients designed to soften, hydrate, or protect thickened skin.
Urea
Urea is commonly used in foot creams because it helps hydrate and soften thick, rough skin. Products with different concentrations are available depending on the severity of dryness.
Alpha Hydroxy Acids
Ingredients such as lactic acid can help loosen and exfoliate excess dead skin while supporting smoother skin texture.
Salicylic Acid
Salicylic acid can help soften and remove thickened skin. It may cause irritation in some people, so it should be used according to product directions.
Petroleum Jelly
Petroleum jelly works primarily as an occlusive barrier, helping reduce moisture loss from the skin. It can be particularly useful as part of an overnight heel-care routine.
Can Cracked Heels Be Prevented?
Yes. Regular foot care is often easier than treating deep fissures after they develop.
Try these preventive habits:
- Moisturize your heels every day.
- Apply cream soon after bathing while the skin is still slightly damp.
- Avoid excessively hot and lengthy showers.
- Use gentle, fragrance-free cleansers.
- Avoid walking barefoot for prolonged periods on rough surfaces.
- Limit frequent use of open-backed footwear.
- Wear properly fitting, supportive shoes.
- Gently manage calluses instead of cutting them.
- Check your feet regularly for new cracks.
- Keep feet clean and dry.
When Should You See a Doctor?
Mild dry heels can often be managed at home, but professional advice is important when the problem is severe, persistent, or associated with other symptoms.
See a healthcare professional if:
- Cracks are deep or repeatedly bleeding.
- You develop increasing pain.
- The skin becomes red, swollen, warm, or increasingly tender.
- There is drainage or pus.
- You develop fever or feel unwell.
- Home treatment does not produce improvement.
- You have diabetes or reduced sensation in your feet.
- You suspect athlete's foot, eczema, psoriasis, or another skin condition.
Deep fissures can become infected, and people with diabetes require particular attention to foot injuries because complications can be more serious.
Cracked Heels and Diabetes
People with diabetes should not treat significant heel cracks as merely a cosmetic issue. Foot sensation can be reduced in some people with diabetes, meaning an injury may go unnoticed. Cracks can also become infected.
If you have diabetes and notice a new, deep, bleeding, painful, or infected-looking heel fissure, seek medical advice rather than relying solely on home treatment.
Common Mistakes to Avoid
Some popular approaches can make irritated heel skin worse.
Avoid:
- Cutting thick heel skin with a blade
- Aggressive scraping
- Very hot water
- Prolonged soaking
- Ignoring deep or bleeding fissures
- Wearing uncomfortable or poorly fitting footwear
- Applying potentially irritating products to open wounds without professional advice
Gentle, consistent care is generally safer than aggressive attempts to remove every bit of hardened skin.
How Long Does It Take for Cracked Heels to Heal?
Healing time varies according to the depth of the fissures and the underlying cause. Mild dryness may improve relatively quickly with regular moisturizing, while thick calluses and deeper cracks can take longer.
If the skin repeatedly cracks despite consistent care, the underlying cause should be investigated rather than simply applying more moisturizer.
Final Thoughts
Cracked heels in adults are common, but persistent or deep fissures should not be ignored. Dry skin, callus buildup, pressure, open-backed footwear, fungal infections, and certain skin or medical conditions can all contribute to the problem.
A simple routine of regular moisturizing, gentle exfoliation, protective footwear, and early attention to new cracks can help restore smoother and healthier-looking heels. For deep, painful, bleeding, infected, or persistent cracks—particularly in people with diabetes—professional medical assessment is important.
