Cracked Heels: Why They Happen, What Helps and When to Seek Care
Cracked heels usually begin with something that seems minor: the skin around the heel becomes dry, rough and thickened. Over time, pressure from standing and walking can make that hardened skin split.
For many people, the problem can be managed with consistent skin care. But deep fissures are different from ordinary dry skin. They can hurt when you stand or walk, bleed, and create an opening through which infection can develop. People with diabetes, reduced sensation in their feet or poor circulation need particular caution because a small foot injury may be harder to notice or heal.
The most useful approach is not to try as many home remedies as possible. It is to soften and protect the skin while reducing the pressure and friction that keep causing it to split.
What Are Cracked Heels?
Cracked heels, also called heel fissures, occur when the skin around the heel becomes excessively dry, thickened or less flexible and then splits under mechanical stress.
The heel normally bears substantial pressure during standing and walking. When the skin along the edge of the heel becomes thick and less flexible, it may not stretch easily as the heel spreads under load. Small splits can then develop and gradually become deeper.
A mild case may look like:
rough or flaky skin;
a hard rim of skin around the heel;
fine lines or shallow cracks;
mild tightness or discomfort.
More advanced fissures may cause:
pain while standing or walking;
deeper splits;
bleeding;
redness around a crack;
swelling or increasing tenderness.
A cracked heel is therefore not always just a cosmetic issue. Once a fissure becomes deep, the priority is protecting the damaged skin and looking for factors that may prevent it from healing.
Why Do Heels Crack?
Cracked heels usually have more than one contributing factor.
Dry, thickened skin
Dry skin loses flexibility. If the skin also becomes thick and callused, it may be less able to accommodate the movement of the heel during walking.
Cold or dry weather, prolonged hot bathing and harsh cleansing can aggravate dry skin. The American Academy of Dermatology recommends keeping bathing relatively brief, using a gentle cleanser and moisturizing soon afterward.
Repeated pressure
Standing and walking place repeated mechanical stress on the heel.
People who spend many hours standing, particularly on hard floors, may be more susceptible. Excess body weight can also increase mechanical loading of the heel.
Open-backed footwear
Flip-flops and other open-heeled footwear do not hold the heel as securely as supportive shoes. The AAD specifically recommends avoiding open-heeled shoes when dealing with dry, cracked heels.
Barefoot walking on hard surfaces
Frequent barefoot walking can expose the heel to friction and pressure and may contribute to thickened skin.
Skin conditions
Persistent or unusual cracking may sometimes be associated with a skin disorder rather than simple dryness. Conditions such as eczema and psoriasis can affect the feet and cause scaling, thickening or fissuring. DermNet also lists hypothyroidism and diabetes among systemic conditions that may be associated with cracked heels.
This matters because treating the dryness alone may not solve the underlying problem.
Could It Be Something Other Than Simple Dry Skin?
Not every rough, cracked foot is simply a dry heel.
Consider professional assessment if the skin is:
unusually itchy or inflamed;
scaling extensively over the foot;
affected between the toes;
repeatedly cracking despite appropriate moisturization;
associated with significant redness or swelling;
developing sores rather than straightforward surface fissures.
For example, athlete's foot can cause scaling and irritation and requires antifungal management rather than simply applying more moisturizer. Keeping feet clean and dry, particularly between the toes, is part of managing this condition.
Likewise, recurrent thick plaques or severe inflammation may warrant assessment for eczema, psoriasis or another skin disorder.
What Actually Helps Cracked Heels?
For uncomplicated cracked heels, a simple routine is generally more useful than a long list of remedies.
1. Moisturize consistently
Moisturization is the foundation of care.
Apply a thick moisturizer to the heel soon after bathing, while the skin is still slightly damp. The AAD recommends products containing ingredients such as 10–25% urea, alpha-hydroxy acids or salicylic acid for dry, cracked heels.
Urea is particularly useful because it can both increase water content in the outer skin and soften thickened skin.
For very dry heels, a plain occlusive such as petroleum jelly can be applied at night. It helps reduce water loss from the skin. The AAD recommends petroleum jelly before bed and notes that socks can help keep it in place.
2. Protect the fissure
If a crack is painful, protecting it from repeated friction can make daily activity more comfortable.
The AAD notes that a liquid bandage can create a protective barrier over heel cracks.
A deep or bleeding fissure, however, should not simply be covered indefinitely without considering why it developed and whether professional assessment is appropriate.
3. Reduce further mechanical stress
Footwear is part of treatment, not merely a prevention measure.
Choose shoes that:
fit comfortably;
provide adequate heel support;
do not rub the affected area;
are not excessively worn;
do not leave the heel unsupported.
If your heels repeatedly crack despite good skin care, footwear and mechanical pressure deserve attention rather than simply adding another cream.
4. Be gentle with thick skin
If there is a thick callus around the heel, gentle smoothing may sometimes be appropriate.
A pumice stone or foot file can be used cautiously after bathing when the skin is softened. The aim is to reduce excessive thickened skin—not to remove as much skin as possible.
More scrubbing is not necessarily better.
Aggressive filing can damage the skin and make fissures worse. Cutting calluses with a razor, blade, scissors or other sharp instrument should be avoided.
People with diabetes, neuropathy or circulation problems should be especially cautious. NIDDK warns against cutting corns and calluses and recommends discussing foot problems with a healthcare professional when appropriate.
Which Ingredients Are Most Useful?
You do not need a complicated collection of foot products.
Urea
Urea is one of the most useful ingredients for dry, thickened heel skin. AAD guidance recommends creams containing 10–25% urea for dry, cracked heels.
It can be particularly useful when the problem involves both dryness and thickened skin.
Petrolatum
Petroleum jelly is a simple occlusive moisturizer. It helps reduce water loss and is especially practical as an overnight treatment.
Glycerin and other moisturizers
Moisturizers containing humectants such as glycerin can help increase water content in the outer skin.
Ceramide-containing products
Ceramides are components of the skin barrier and are commonly used in moisturizers formulated for dry or compromised skin.
Alpha-hydroxy acids or salicylic acid
These ingredients can help soften thickened skin, but stronger keratolytic products are not appropriate for every person. They can irritate sensitive or damaged skin if used too aggressively.
For most people, the simplest starting point is a moisturizer containing urea followed by an occlusive such as petroleum jelly when needed.
Do Natural Remedies Help?
Some household oils and plant-derived products can soften dry skin because they act as emollients. However, there is no need to treat every natural ingredient as a separate "remedy."
Coconut oil, shea butter and similar emollients may make dry skin feel softer, but the evidence and practical importance are not equivalent to the established role of regular moisturization and ingredients such as urea.
Honey, aloe vera and other home treatments should not be relied upon for deep fissures, suspected infection or wounds associated with diabetes.
The important question is not whether an ingredient is natural. It is whether it is appropriate for the condition, safe for the individual and supported well enough to justify using it.
What Should You Avoid?
Several common habits can keep cracked heels from improving.
Avoid aggressive scrubbing
Removing large amounts of hard skin can expose vulnerable tissue and create additional irritation.
Avoid cutting calluses yourself
Blades and scissors can cause wounds and infection. This is particularly important if you have diabetes or reduced sensation.
Avoid very hot or prolonged soaking
Long or hot bathing can worsen dryness. The AAD recommends limiting baths and showers to about 5–10 minutes and using warm rather than excessively hot water.
A brief warm wash is sufficient. You do not need a lengthy foot soak to make a moisturizer effective.
Avoid irritating products
Strongly fragranced products or products that sting damaged skin may increase irritation. A gentle, fragrance-free cleanser can be a better choice for sensitive skin.
Do not put moisturizer between the toes
The skin between the toes has different moisture needs from the heel. In people at risk of foot problems, excessive moisture between the toes can contribute to skin problems. NIDDK specifically advises keeping these areas dry.
A Simple Routine for Recurrent Cracked Heels
A practical routine can be kept very simple.
After bathing
Use warm rather than very hot water.
Cleanse gently.
Pat the feet dry rather than rubbing aggressively.
Apply a heel cream while the skin remains slightly damp.
Give particular attention to the thickened heel area.
At bedtime
Apply a generous layer of moisturizer.
If the heels are very dry, apply petroleum jelly over the moisturizer.
Wear comfortable clean socks if helpful.
During the day
Wear supportive footwear and avoid repeated friction against the heel.
If the skin becomes increasingly painful, red, swollen or open, stop treating the problem as simple dryness and consider professional assessment.
What Changes If You Have Diabetes?
This is one of the most important distinctions in the article.
Diabetes can affect the feet through nerve damage and reduced blood flow. Peripheral neuropathy may reduce the ability to feel pain or injury, while impaired circulation can make wounds harder to heal.
That means a person with diabetes should not approach a cracked or broken heel in exactly the same way as someone with uncomplicated dry skin.
NIDDK recommends checking the feet every day and seeking medical attention for concerning foot changes. It also advises against cutting corns and calluses and emphasizes appropriate footwear and foot care.
If you have diabetes, particularly if you have neuropathy, previous foot ulcers or circulation problems, ask your healthcare professional how to manage callused or cracked areas rather than relying on aggressive home exfoliation.
When Should You See a Healthcare Professional?
Seek professional evaluation if:
the fissure is deep or repeatedly bleeding;
pain is significant or makes walking difficult;
redness, warmth or swelling develops;
there is pus, drainage or an unpleasant odor;
the area is becoming increasingly painful;
a crack becomes an open sore;
the problem repeatedly returns despite appropriate care;
you have significant numbness or loss of sensation in the feet;
you have diabetes and develop a break in the skin;
you have poor circulation or another condition that affects wound healing;
you suspect eczema, psoriasis, athlete's foot or another skin condition.
NIDDK advises people with diabetes to contact their healthcare provider promptly for concerning foot changes such as cuts or sores that are not beginning to heal, or skin that becomes red, warm or painful.
Severe infection or rapidly worsening symptoms require prompt medical attention.
How Can You Prevent Cracked Heels From Returning?
Once the fissures improve, prevention is mainly about maintaining the skin barrier and reducing mechanical stress.
A practical maintenance plan is:
moisturize your heels regularly;
use a urea-containing cream if your heels remain thick and dry;
use petroleum jelly when extra occlusion is helpful;
avoid very hot, prolonged bathing;
choose supportive footwear;
avoid repeatedly walking barefoot on hard surfaces if this worsens your heels;
deal with early dryness before deep cracks develop;
avoid aggressive callus removal;
inspect your feet regularly if you have diabetes or reduced sensation.
If your heels repeatedly crack despite these measures, the goal should not simply be to find a stronger cream. Recurrent fissuring may justify looking for an underlying skin condition, medication-related dryness, mechanical problem or medical condition.
Key Takeaways
Cracked heels usually develop when dry or thickened skin is exposed to repeated mechanical pressure.
Consistent moisturization is more important than collecting numerous home remedies.
Urea-containing creams and petroleum jelly are practical evidence-supported options for dry, cracked heels.
Gentle care is preferable to aggressive filing, scraping or cutting.
Open-backed footwear and repeated mechanical stress can contribute to recurrence.
Persistent scaling, inflammation or itching may indicate another skin condition rather than simple dryness.
People with diabetes, neuropathy or circulation problems need extra caution because foot injuries can be harder to detect or heal.
Deep, bleeding, infected or non-healing fissures should be professionally evaluated.
