Foot Skin Cracking: What to Know

Fissures develop when stiff or dehydrated skin cannot flex comfortably, especially around the heel or pressure points. Friction, frequent washing, dry air, and open footwear may contribute. Atopic dermatitis can cause itch and inflammation, while psoriasis may produce thick scale that splits. Pain can come from the crack itself, and broken skin provides an entry point for infection; the presence of a fissure does not identify its cause.

Clean gently, pat dry, and apply a thick fragrance-free moisturiser while the skin is slightly damp. Emollient therapy can soften scale and support the skin barrier. Wear well-fitting shoes and cushioned socks, and avoid picking, sharp blades, and vigorous filing over an open fissure. If cracks recur despite consistent care, a clinician can assess for eczema, psoriasis, infection, or another contributor and choose a suitable prescription.

Arrange an assessment for deep, bleeding, very painful, or repeatedly infected cracks. Get prompt help if warmth, spreading redness, swelling, pus, fever, or red streaking develops. A crack that prevents normal walking, or one that does not improve with careful moisturising, needs a closer look.

Is the cracking caused by dryness, eczema, psoriasis, or infection? Which emollient and dressing suit the fissure? Should I change footwear or foot-care habits? What should I do if it bleeds?
