What should you know about crack heel remedy at home?

A heel fissure is a split in dry or thickened skin. Moisture helps the outer layer become more flexible, while a dressing shields the split from rubbing and dirt. Cracks may be more stubborn when the heel is exposed in sandals, when shoes rub, or when the skin is affected by Dry Skin or Athlete's Foot. Home measures are suitable for a small, uncomplicated crack, not for a deep wound or a foot with reduced sensation.

Clean the foot with lukewarm water and a gentle cleanser, then pat it completely dry. Apply a thick emollient to the heel and repeat as directed on the product label; keep slippery product off the floor. Cover an open split with a clean dressing and change it when wet or dirty. Wear closed, well-fitting shoes and clean socks that reduce friction. Avoid blades, strong acids, and aggressive scraping. If scale persists or spreads, ask a pharmacist or clinician whether it needs treatment beyond moisturising.

Arrange medical care if the crack becomes more painful, red, warm, swollen, or wet, or if you notice pus, fever, or a bad smell. Seek prompt assessment for a deep or bleeding fissure, difficulty walking, or symptoms that do not settle with careful care. People with diabetes, poor circulation, neuropathy, or immune problems should obtain personalised foot advice before treating a persistent open crack at home.

Is home treatment appropriate for the depth of this crack? Which emollient and dressing should I use? Could a fungal infection be involved? How should I protect my foot if sensation or circulation is reduced?
