Cracked Heels (Heel Fissures) – Beyond the Cosmetic Problem
You've probably noticed the cracks—unsightly fissures running across your heels that seem to worsen as Florida's dry season progresses. While many people dismiss cracked heels as merely a cosmetic concern, the reality is quite different. Heel fissures can become painful, lead to infection, and indicate underlying foot conditions that deserve proper attention. At Central Florida Foot & Ankle Institute, Dr. Carli Hoover helps patients understand what causes cracked heels and how to treat them properly before they develop into serious problems.
What Are Heel Fissures?
Heel fissures are deep cracks in the skin on your heel. The cracks typically run perpendicular to the skin surface and can range from shallow, barely noticeable splits to deep, painful fissures that penetrate through multiple layers of skin. Depending on their severity, they can cause pain, bleed, become infected, or expose deeper tissue layers.
Unlike cracked skin elsewhere on your body, heel fissures are particularly common and problematic because your heel experiences enormous pressure with every step you take. Your heels bear 50 percent of your body weight while walking and must absorb substantial impact forces. Additionally, the skin on your heels has fewer oil glands than skin elsewhere on your body, making it naturally drier and more prone to cracking.
Why Your Heels Crack: Multiple Contributing Factors
Dry Skin (Xerosis)
Dehydrated skin is the foundation for heel fissures. In Florida, despite our humidity, indoor air conditioning and various environmental factors can dry your skin significantly. Heels are particularly vulnerable because the skin there naturally has fewer sebaceous glands—the glands that produce protective oils—compared to other body areas.
As you age, your skin produces less of the natural oils that keep it supple and prevent cracking. This is why heel fissures become more common with advancing age.
Foot Mechanics and Pressure Distribution
Your heel's structural characteristics make it prone to fissuring. The skin on your heel must stretch and compress with each step. If your foot mechanics place excessive pressure on specific areas of your heel, or if your heel pad is thin or doesn't function optimally, the repeated stress can cause the skin to crack.
Foot Structure Issues
Certain foot structures increase fissure risk. If you have flat feet (pes planus) or high-arched feet (pes cavus), your heel may bear pressure differently, concentrating stress in certain areas. This unequal pressure distribution can accelerate fissure formation.
If you overpronate (your foot rolls inward excessively) while walking, the position of your heel when it contacts the ground changes, and pressure distribution shifts toward the inner edge of your heel, increasing fissure risk.
Plantar Fasciitis Connection
The plantar fascia—the thick ligament running along the undersurface of your foot from your heel to your toes—connects to your heel bone. When your plantar fascia becomes tight and inflamed (plantar fasciitis), it increases stress on your heel. This increased mechanical stress accelerates heel fissure formation. Many people with plantar fasciitis also develop heel fissures.
Weight and Activity
Your body weight significantly affects heel pressure. Carrying extra weight increases the force through your heel with every step. Similarly, increased activity—particularly walking or standing on hard surfaces—increases the mechanical stress causing heel fissures.
Floridians who are very active—whether that's training for athletics in the summer heat, working on their feet during our warm season, or staying active throughout the year—may be more prone to heel fissures due to increased activity levels.
Footwear Choices
Open-back shoes like sandals and flip-flops, while comfortable in Florida's climate, can contribute to heel fissures. Without support around the heel, the heel pad spreads laterally with each step, stretching the skin and increasing fissure risk. Backless shoes also fail to contain moisture, allowing heels to dry out more rapidly.
Conversely, tight shoes that rub excessively can also cause problems, though usually more localized to specific areas of the heel.
Medical Conditions
Certain underlying conditions increase heel fissure risk significantly. Diabetes, particularly if your blood sugar control isn't optimal, reduces your skin's ability to heal and increases skin dryness. Hypothyroidism, psoriasis, atopic dermatitis, and other skin conditions are associated with increased fissuring.
Environmental Factors
While Florida's climate is warm and humid, spending time in air conditioning, which dries indoor air, can paradoxically increase skin dryness. Harsh soaps or certain foot products can strip away natural skin oils. Walking barefoot on hard, dry surfaces increases fissure risk.
Symptoms Beyond Cosmetic Concerns
Pain
Unlike shallow cracks, deep heel fissures hurt. The pain typically feels like a sharp, burning sensation, particularly when you're on your feet or bearing weight. Pain often worsens toward the end of the day after you've been standing or walking. The pain can be severe enough to limit activity or affect your gait.
Bleeding and Infection Risk
Deep fissures can bleed, creating visible blood stains on your socks or shoes. More concerning is the infection risk. Fissures create openings in your skin barrier that allow bacteria to enter. If you have diabetes or any condition affecting your immunity or sensation, infection risk is substantially elevated.
Infected heel fissures can develop cellulitis (a spreading skin infection) or abscess formation, creating serious medical complications. Some patients require systemic antibiotics or drainage procedures for infected fissures.
Functional Limitations
Severe heel fissures can limit your ability to walk comfortably, wear certain shoes, or participate in water-based activities. Many people with painful heel fissures alter their gait to reduce heel pressure, which can cause secondary knee, hip, or back pain.
Diagnosis: Understanding Your Fissures
Dr. Carli Hoover diagnoses heel fissures through clinical examination. She'll assess the depth of your fissures, evaluate whether they're bleeding or infected, and look for signs of underlying skin conditions or infections.
She'll evaluate your foot structure and mechanics to understand whether biomechanical factors are contributing to your fissures. She'll assess whether your feet are dry due to environmental factors or whether you might have an underlying medical condition causing xerosis.
If you have diabetes or other medical conditions, Dr. Hoover will take extra care to monitor for signs of infection and provide specific guidance based on your medical history.
Treatment Approaches
Prevention and Early-Stage Management
Moisturization: Regular moisturizing is fundamental. Use creams containing urea or alpha-hydroxy acids (AHAs), which help soften hardened skin. Avoid lotions; creams and ointments are more effective. Apply moisturizer immediately after bathing when skin is still hydrated.
Pumice Stone Use: Gently remove dead skin using a pumice stone during or after bathing when skin is soft. Overly aggressive removal or using a pumice stone on non-softened skin can worsen fissures.
Hydration: Drink adequate water and avoid excessive caffeine or alcohol, which can dehydrate your skin.
Footwear: Wear supportive shoes with enclosed heels when possible. Avoid backless shoes that allow lateral heel spreading. Choose shoes with adequate heel cushioning. If you prefer open-back shoes, look for styles with heel straps that provide containment.
Activity Modification: Reduce time spent barefoot on hard, dry surfaces. Avoid standing or walking excessively on hard floors.
Active Fissure Treatment
Professional Skin Removal: Dr. Hoover or our clinical staff can safely remove dead skin from your heels, reducing fissure depth and improving appearance. This is done carefully, particularly in patients with diabetes or other conditions affecting wound healing.
Heel Creams and Treatments: Specialized heel creams containing keratolytic agents help soften and remove dead skin. Some contain ingredients like salicylic acid that break down dead skin more effectively than standard moisturizers.
Bandaging and Taping: For painful fissures, we apply supportive tape or wrapping that stabilizes the heel skin and reduces movement of fissure edges, promoting healing and reducing pain. These techniques work particularly well for fissures that are bleeding or at high infection risk.
Heel Cups or Inserts: Custom or over-the-counter heel cups provide cushioning and reduce heel pad expansion, both helping healing and reducing pain. Proper heel support is particularly important if plantar fasciitis is contributing to your fissures.
Orthotics: If your foot mechanics are contributing to your fissures—such as excessive pronation or high-arched foot structure—custom orthotics correct your biomechanics and distribute heel pressure more evenly. This addresses the root cause rather than just treating symptoms.
Treatment for Severe or Infected Fissures
Severe, deep fissures or infected fissures require more aggressive intervention. We may apply protective coverings, prescribe topical antibiotics, or in cases of significant infection, recommend oral antibiotics.
For severe fissures that aren't healing despite appropriate care, surgical approaches like heel pad injection or surgical closure may become appropriate, though these are rarely needed.
Managing Underlying Conditions
If your heel fissures are related to diabetes, thyroid disease, psoriasis, or other medical conditions, optimizing management of those conditions helps your skin heal and prevents recurrence. We coordinate care with your primary care physician or dermatologist as needed.
Patients with diabetes require particularly careful foot care, and we provide specific guidance about infection prevention and appropriate treatments.
Long-Term Prevention
Once your fissures have healed, preventing recurrence requires ongoing attention. Daily moisturizing, appropriate footwear, regular skin maintenance, and managing any biomechanical or medical conditions that contributed to your fissures keeps your heels healthy.
Many patients benefit from continuing to use specialized heel creams or performing regular gentle pumicing to prevent dead skin accumulation. Maintaining proper hydration and avoiding excessive dry environments helps preserve skin health.
When to Seek Professional Care
Schedule an appointment if you develop heel fissures that don't improve with home care after a few weeks, if your fissures are painful or bleeding, if you have signs of infection, or if you have diabetes and develop any heel changes. Early professional intervention prevents complications and promotes faster healing.
