Cracked heels

Rhagades
Medically reviewed · Hottinger Podologie, ZurichUpdated: July 2026

Heel fissures (rhagades) are tears in thickened, dry callus, most often on the heel. Superficial cracks feel tight and burn; deep fissures reach into the dermis, hurt when walking and can bleed. They are then also a possible entry point for bacteria.

Common causes
  • Dry skin, more pronounced with age and in winter
  • Thick callus layers under constant load
  • Open shoes, excess weight, long standing
  • Contributing factors: diabetes, skin conditions, fungal infections
What you can do yourself

Consistent rich moisturising (for example with urea), keep callus gently thin with a file rather than a plane or blade, wear closed, well-cushioned shoes. What does not help: taping over the cracks and carrying on as before.

When to see a podiatrist

If cracks hurt, bleed, become inflamed or keep returning despite care. In the practice the thickened callus is reduced layer by layer, the fissures are treated, and you receive a care plan so it stays that way.

Did you know?

Fissures peak in winter: dry heating air draws additional moisture from the skin of the feet, although open summer shoes promote them as well.
