Extreme heel cracks: what to know

Heel fissures form when dry, thickened skin loses flexibility and splits under pressure. Open-backed shoes, prolonged standing, dry air, frequent hot bathing, and friction can make the edges harder and deeper. Athlete's Foot may also cause scaling or cracking, especially between the toes and along the sole.

Pain while walking, bleeding, or a crack that catches on fabric suggests more than simple surface dryness. Diabetes, reduced circulation, eczema, psoriasis, or medicines that dry the skin can affect healing, so the wider health picture matters.

After washing, pat the feet dry and apply a thick fragrance-free moisturiser while the skin is still slightly damp. Cover a painful fissure with a clean dressing to limit friction, and choose closed, well-fitting footwear with soft socks. A short soak can soften hard skin, but avoid prolonged soaking and do not cut or shave the thickened edges. A clinician or pharmacist can recommend Emollient Therapy and check whether fungal treatment is needed.

Arrange an assessment for deep, recurrent, bleeding, or very painful cracks, especially if home care is not helping. Seek prompt care for increasing redness, warmth, swelling, pus, red streaks, fever, or difficulty walking. If you have diabetes, poor circulation, reduced sensation, or immune problems, ask for advice early because a small opening can need closer monitoring.

Ask whether the fissures are driven by dryness, Athlete's Foot, eczema, or another condition. Ask which moisturiser, dressing, and footwear changes suit your skin, and what signs should prompt a return visit.
