Cracked heels — also known as heel fissures — are one of the most common and frustrating foot problems people face. While they may seem like a purely cosmetic concern, cracked heels can cause real discomfort and, in more serious cases, lead to pain, bleeding, and even infection. Understanding what causes them and what you can do about them is the first step toward smooth, healthy feet.

What Causes Cracked Heels?

The skin on the heel is naturally thicker than elsewhere on the body, which makes it prone to dryness and cracking when it loses moisture. Several factors contribute to this condition.

Dry skin is the most common culprit. When the skin on the heel becomes too dry, it loses its elasticity and begins to crack under the pressure of standing, walking, and daily movement. Cold weather, low humidity, and prolonged exposure to hot water can all strip the skin of its natural oils.

Prolonged standing puts continuous pressure on the fat pad under the heel, causing it to expand sideways. If the surrounding skin isn’t supple enough to accommodate this expansion, it cracks.

Footwear plays a significant role. Open-backed shoes and sandals allow the heel to be exposed, which leads to increased moisture loss and more friction. Thin-soled shoes also increase pressure on the heel without adequate cushioning.

Medical conditions such as diabetes, hypothyroidism, eczema, psoriasis, and athlete’s foot can all contribute to cracked heels. Diabetics in particular need to be vigilant, as reduced circulation and nerve damage can mean that cracks go unnoticed and worsen quickly.

Obesity increases the pressure on the heel pad, accelerating the cracking process. Meanwhile, aging naturally reduces the skin’s ability to retain moisture, making older adults more susceptible.

Understanding your personal risk factors is key to choosing the right treatment and prevention strategy.

How to Treat Cracked Heels

Fortunately, the vast majority of cracked heel cases can be treated effectively at home with consistency and the right products.

1. Moisturise Regularly and Thoroughly

The cornerstone of treating cracked heels is moisturisation. Apply a thick, emollient-rich foot cream twice daily — once in the morning and once before bed. Look for creams containing urea (10–25%), glycerin, shea butter, lanolin, or salicylic acid. Urea is particularly effective because it not only hydrates but also softens and gently exfoliates thickened skin.

For best results, apply moisturiser immediately after bathing while the skin is still slightly damp to lock in moisture. At night, apply a generous layer of cream and then put on a pair of clean cotton socks. This “soak and seal” method can dramatically improve the condition of cracked heels within days.

2. Soak and Exfoliate

Soaking your feet in warm (not hot) water for 15–20 minutes softens the hardened skin, making it easier to exfoliate. After soaking, gently use a pumice stone or foot file on wet skin to remove dead, thickened cells. It’s important to be gentle — over-filing can cause irritation or bleeding. After exfoliation, dry the feet thoroughly, paying particular attention to between the toes, and immediately apply moisturiser.

Avoid soaking your feet for too long or using very hot water, as this can actually dry out the skin further and make the problem worse.

3. Use Liquid Bandage for Deep Cracks

For heels that are already deeply cracked or bleeding, a liquid bandage or skin glue can be applied directly to the fissures. This helps hold the skin together, allows healing to begin, and prevents painful opening of the wound during movement. Products such as medical-grade cyanoacrylate glues are available over the counter and can provide significant relief.

4. Wear Supportive, Enclosed Footwear

Switching from open-backed shoes and sandals to closed, well-cushioned footwear reduces both moisture loss and lateral pressure on the heel. Look for shoes with a thick, cushioned sole and a snug (but not tight) heel cup. Avoid walking barefoot on hard surfaces such as tiles or concrete, which increase pressure and promote dryness.

5. Hydrate from the Inside Out

Drinking adequate water throughout the day supports overall skin health. While topical treatment is essential, hydration from within plays a supporting role in maintaining skin elasticity.

When to See a Doctor

While most cracked heels respond well to home treatment, there are situations where professional medical attention is necessary.

If your heels are deeply cracked, bleeding, infected, or painful to walk on, see a podiatrist or GP. A podiatrist can safely remove thickened skin using professional instruments and prescribe stronger treatments such as prescription-strength urea creams or heel balms.

People with diabetes or poor circulation should seek professional advice at the first sign of cracking. Because diabetics may not feel pain normally, a small crack can become a serious ulcer or infected wound without warning. Regular podiatry appointments are strongly recommended for this group.

If cracked heels are recurring despite diligent home care, a doctor may investigate underlying conditions such as thyroid dysfunction, eczema, or nutritional deficiencies (particularly zinc and omega-3 fatty acids) that could be contributing to the problem.

Long-Term Prevention

Once your heels have healed, the goal shifts to prevention. Establish a daily foot care routine that includes moisturising after each shower, gentle weekly exfoliation, and wearing appropriate footwear year-round. Keep a foot cream on your bedside table so that the nightly routine becomes second nature.

Maintaining a healthy weight, staying hydrated, and managing any underlying health conditions are all important long-term strategies. During winter months or in dry climates, consider using a humidifier in your home to help maintain ambient moisture levels and reduce skin dryness overall.

Conclusion

Cracked heels are common, but they are far from inevitable. With a consistent routine of moisturising, gentle exfoliation, protective footwear, and adequate hydration, most people can achieve and maintain smooth, healthy heels. For those with more severe cases or underlying health conditions, professional care is just a step away. The feet carry us through every moment of our lives — they deserve a little extra attention.
