What should you know about thick skin peeling off heel?

A heel can develop a hard outer layer when repeated loading and rubbing exceed the skin's ability to stay flexible. As that layer dries, it may flake or lift, especially around a crack. Itch and fine scale on the sole or between toes can occur with Athlete's Foot. Persistent sharply bordered scale can occur with Psoriasis, and tender peeling after intense exposure can follow Sunburn. These appearances overlap, so the distribution and symptoms matter more than the loose skin alone.

Rinse with lukewarm water, pat dry, and use a rich moisturiser on intact skin. Choose supportive shoes and socks that limit rubbing, and change damp socks promptly. Leave attached skin in place; do not rip it away or shave the heel. A clean dressing can protect a shallow crack from friction. Avoid sharing towels if a fungal infection is possible, and seek advice about treatment rather than layering several products on irritated skin.

Arrange a clinical review when peeling returns repeatedly, spreads beyond the heel, or causes persistent itch, pain, bleeding, or deep cracks. Seek prompt care for pus, increasing warmth, swelling, spreading redness, fever, or trouble bearing weight. If you have diabetes, circulation problems, or reduced sensation, have any open heel area checked early.

Could this be Athlete's Foot, Psoriasis, Sunburn, or pressure-related dryness? What should I apply to cracks, and how can I prevent friction while the cause is being assessed?
