What causes cracks in the heels?

Open footwear, prolonged standing, friction, and hot showers can remove protective oils and make heel skin rough. The thick skin at the edge of the heel may then widen as you walk. Eczema, psoriasis, or a fungal infection such as Athlete's Foot can also cause scaling and cracking. Itching between the toes, peeling, or an unpleasant odour makes infection more relevant. Cracks that bleed or sting are breaks in the skin, so germs can enter more easily.

Wash gently with warm water, pat dry, and apply a rich moisturiser while the skin is still slightly damp. An emollient can soften the thick rim; cover it with cotton socks overnight. Wear supportive shoes that protect the heel and avoid cutting the hard skin with blades. A pharmacist or dermatologist can advise whether an antifungal product or a structured Emollient Therapy plan is appropriate.

Arrange medical advice if a crack is deep, repeatedly bleeding, increasingly painful, warm, swollen, or producing fluid. Seek prompt assessment if you have diabetes, reduced feeling in your feet, or poor circulation, because a small wound may need closer monitoring. Urgent care is appropriate for spreading redness, fever, or rapidly worsening pain.

Could this be eczema, psoriasis, or Athlete's Foot? Which moisturiser suits the thickness and location of the cracks? How should I protect a bleeding fissure while it heals?
