Quick answer: Dry cracked heels (heel fissures) occur when the skin on the heel becomes thick and dry, then splits under the pressure of weight-bearing. Contributing factors include dry skin, prolonged standing, open-back footwear, obesity, and systemic conditions like diabetes or hypothyroidism. Treatment involves regular urea-based moisturizers, gentle debridement, and protective footwear.
Cracked heels are one of the most common foot problems we see — and one of the most neglected. What starts as dry, rough heel skin that looks cosmetically unpleasant can progress to deep, painful fissures that bleed, become infected, and significantly impact daily activities. For diabetic patients in particular, cracked heels are a serious wound-care concern that can escalate rapidly.
Dr. Tom Biernacki, DPM explains why heel fissures form, what makes them worse, and the most effective treatment and prevention strategies at Balance Foot & Ankle.
Why Do Heels Crack?
The heel skin is under unique mechanical stress — it bears the concentrated weight of the entire body with every step, and the fat pad beneath it spreads outward under load. When the surrounding skin is dry and thickened, it can’t flex adequately with this spreading motion and splits. The process starts with xerosis (abnormal skin dryness) or hyperkeratosis (abnormal skin thickening) building up on the heel perimeter, and progresses to fissures (splits) when the brittle skin can no longer withstand the stress.
Key takeaway: The combination of heel callus formation plus open-back footwear (flip flops, sandals, clogs) is the most common driver of heel fissures. Open backs allow the heel fat pad to spread unconstrained with each step, dramatically increasing lateral skin tension and cracking.
Contributing Factors
- Dry skin (xerosis) — reduced natural oil production, harsh soaps, low humidity environments
- Open-back footwear — allows unconstrained heel fat pad spread, increasing skin tension
- Prolonged standing — continuous pressure and friction accelerate callus and fissure formation
- Obesity — increases downward pressure on the heel fat pad, amplifying lateral spreading forces
- Diabetes — autonomic neuropathy reduces sweat gland function, causing extreme foot skin dryness; peripheral neuropathy impairs early sensation of fissures
- Hypothyroidism — severely dry, rough skin across the body, including the feet
- Psoriasis — hyperkeratotic plaques on the heels prone to fissuring
- Age — skin becomes less elastic and produces less oil with age
Dry Cracked Heel Treatment
Urea-Based Creams
Urea cream (20–40%) is the most effective topical treatment for dry cracked heels. Urea is keratolytic (it chemically softens and dissolves thickened skin) and humectant (it draws water into the skin). Apply 20% urea cream to clean, damp heels twice daily — after a shower is ideal, when the skin is softened. For thick callused heels, 40% urea cream or an occlusive overnight treatment (thick cream + cotton socks over it) dramatically accelerates improvement. Results are typically visible within 1–2 weeks of consistent use.
Mechanical Debridement
Gentle mechanical removal of thickened callus — using a pumice stone or foot file after soaking — reduces the volume of dry skin before moisturizer application, allowing better penetration. Soak the feet for 10 minutes in warm water first to soften the callus, then gently file in one direction (not back-and-forth). Do not use razor blades or scalpel blades on your own feet — professional debridement at our clinic is safe; home razor use carries significant infection risk, especially in diabetics.
Footwear Modification
Eliminating open-back footwear is often the single most impactful change for recurrent heel fissures. Replace flip flops and backless clogs with enclosed, cushioned footwear — particularly at home on hard floors, where most heel callus develops. A small heel cup or silicone heel pad inside shoes provides additional support and prevents the fat pad from over-spreading.
Liquid Bandage for Deep Fissures
For fissures that are actively bleeding or painfully open, a liquid bandage (cyanoacrylate tissue adhesive) applied into the crack provides immediate pain relief by sealing the wound, allows normal weight-bearing, and protects the split during healing. This is particularly valuable for patients who need to remain active. Apply after drying the fissure edges; multiple applications may be needed as the crack heals.
Professional Debridement
For severely thickened, fissured heels — particularly in diabetic patients — professional debridement using sterile instruments in our clinic safely removes the buildup that home pumice can’t address. We also apply medical-grade keratolytic agents and can assess for any signs of infection at the fissure base.
⚠️ When to see a podiatrist:
- Diabetic patient with any heel crack, especially deeper than superficial skin (high ulceration risk)
- Fissure that is red, warm, or has pus at the base (infected — needs antibiotic treatment)
- Heel crack extending through to bleeding tissue
- Cracked heels that don’t respond to 4 weeks of daily moisturizing (possible psoriasis or systemic cause)
- Extremely dry skin across the entire body with fatigue and cold intolerance (hypothyroidism screen)
Frequently Asked Questions
What is the best cream for cracked heels?
Urea-based creams (20% for maintenance, 40% for severe cases) have the strongest evidence for heel fissure treatment. Effective OTC options include Eucerin Roughness Relief Cream, AmLactin, and CeraVe Healing Ointment. Apply to damp skin after bathing, cover with cotton socks overnight for maximum absorption. Consistency is more important than brand — apply twice daily without skipping.
How long does it take to heal cracked heels?
Superficial fissures typically resolve in 1–2 weeks with consistent moisturizing and footwear changes. Severely thickened heels with deep fissures may take 4–8 weeks to fully improve. Without addressing the contributing factors (open footwear, prolonged standing), fissures recur reliably — so prevention with daily moisturizing and enclosed footwear is essential after healing.

🧴 Topical Repair Cream: Doctor Hoy's Natural Pain Relief Gel
For painful cracked heels with inflammation and discomfort, I recommend Doctor Hoy's Natural Pain Relief Gel alongside your urea cream regimen. The arnica and camphor formula reduces pain and inflammation so you can tolerate the moisturizing process. Apply directly to the cracked, inflamed areas 3–4x daily. This is what we use in our clinic for heel fissure management.

👟 Arch Support Insoles: PowerStep Pinnacle
Chronically dry, cracked heels are often caused by excessive weight load and flat-footed biomechanics that spread the heel pad outward, causing fissuring. PowerStep Pinnacle insoles provide the medial arch support that reduces abnormal heel loading — addressing the mechanical cause, not just the symptom. The OTC orthotic I recommend most in our clinic.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
Severely cracked heels (heel fissures) require a two-step approach: physical debridement followed by intensive hydration. Step 1: Soak the foot for 15 minutes in warm water, then use a pumice stone or foot file to mechanically reduce the callus rim — it’s the thick, dry callus at the fissure edges that prevents healing. Attempting to moisturize without debridement is like trying to hydrate through a wall of concrete. Step 2: Immediately after drying, apply urea 20–40% cream (prescription strength has better evidence than OTC versions) and seal it with a breathable sock or occlusive bandage overnight. Urea is both a humectant and a keratolytic — it draws moisture in AND softens the thickened skin. In severe cases where fissures have broken through to the dermis and are bleeding or infected, a podiatrist can apply a liquid bandage (cyanoacrylate) to close the crack and allow pain-free walking while healing proceeds. Address the root cause: poorly fitting footwear that causes medial heel shear, open-back shoes that allow heel spread, or systemic dryness from diabetes, hypothyroidism, or dermatological conditions.
