What should you know about really cracked heels?

Heel fissures form when thick, dry skin loses flexibility and splits under pressure. Open cracks may sting while walking and can catch on socks or bedding. Dry skin, long periods of standing, open-backed shoes and hot showers can all contribute. Athlete's Foot may also cause scaling or splitting, especially if itching or peeling affects the spaces between the toes. Cracked skin is not automatically a sign of infection, but warmth, swelling, drainage or spreading redness needs attention.

Wash with lukewarm water, pat dry, then apply a thick emollient while the skin is still slightly damp. Cover the heels with cotton socks overnight. A foot file can gently smooth loose thickened skin after bathing; do not cut the cracks with blades or remove living skin. Choose closed, well-fitting shoes and avoid walking barefoot on hard floors. A clinician can recommend Emollient Therapy or check for fungal involvement when home care is not enough.

Arrange prompt medical care for a deep or bleeding fissure, pus, increasing pain, spreading redness, warmth, swelling or fever. Seek earlier assessment if you have diabetes, reduced sensation, poor circulation or a weakened immune system, because a small foot wound may need closer monitoring. Book a dermatology appointment when repeated cracking continues despite consistent moisturising or when severe scaling affects both feet.

Could this be Athlete's Foot or another skin condition? Which moisturiser and strength are suitable for my heels? Is the fissure deep enough to need a dressing or prescription treatment? How should I protect my feet if I have diabetes or reduced sensation?
