Cracked Heels: what it usually means
Also searched as: heel fissures, dry cracked heels, split heels, heel cracks · Updated 19 Aug 2026 · Educational — not medical advice
The short answer: Cracked heels are usually caused by dry skin, prolonged standing, or wearing open-backed footwear, and mild cracks typically heal within a few weeks with regular moisturizing. Thickened, dry skin around the heel rim is often the first sign before visible splits appear. Deep, painful cracks that bleed, or cracked heels in someone with diabetes, need prompt care to prevent infection.
See a doctor promptly if…
Deep cracks that bleed or cause significant pain need prompt medical evaluation.
Cracked heels in someone with diabetes should be checked regularly to prevent infection.
Signs of infection, such as redness, warmth, or discharge, need urgent care.
Cracks that don't improve after consistent moisturizing and care for several weeks warrant a doctor's review.
Common causes
- Dry skin — Low humidity, frequent hot showers, or naturally dry skin reduces the heel's flexibility, leading to cracks.
- Prolonged standing — Extended time on hard surfaces increases pressure on the heels, contributing to thickened, cracked skin.
- Open-backed footwear — Sandals and shoes without back support allow the fat pad to expand sideways, promoting cracks.
- Excess body weight — Extra body weight increases pressure on the heels, worsening dryness and cracking.
- Underactive thyroid — Hypothyroidism can cause generalized dry skin, including thickened, cracked heels.
- Diabetes — Reduced circulation and nerve sensitivity can worsen dryness and delay healing of heel cracks.
What helps
- Moisturize the heels daily with a thick, urea- or petroleum-based cream, especially after bathing.
- Use a pumice stone gently on damp skin — but if you have diabetes, neuropathy, or poor circulation, skip self-filing entirely and have a clinician or podiatrist manage thickened skin, because small wounds can become serious.
- Wear closed-back, cushioned footwear to reduce pressure and friction on the heels.
- Stay hydrated and avoid prolonged very hot showers that strip natural skin oils.
Which doctor to consult
Most cracked heels respond to regular moisturizing; see a dermatologist for deep, painful, or non-healing cracks, especially with diabetes.

Questions people ask
Why do my heels crack more in certain seasons?
Cracked heels are often more common in dry, cold weather or in hot climates with frequent open-footwear use, both of which reduce skin moisture and flexibility. Consistent moisturizing and appropriate footwear year-round can help minimize seasonal flare-ups of heel cracking.
Are cracked heels more serious for people with diabetes?
Yes, diabetes can reduce circulation and nerve sensation in the feet, which slows healing and increases the risk of cracked heels progressing to infection without being noticed. Regular foot checks and prompt care for any cracks are especially important for people managing diabetes.
What ingredients in moisturizers work best for cracked heels?
Creams containing urea, salicylic acid, or petroleum jelly are particularly effective for cracked heels because they soften thickened skin and lock in moisture. Applying them consistently, especially at night with socks afterward, tends to give the best results for healing dry, cracked skin.
