Bottom of Foot Skin Cracking: Causes and Care

The heel and other weight-bearing areas can become thick and less flexible, allowing splits to form with walking or friction. Atopic dermatitis may leave skin dry, inflamed, and prone to fissuring. Psoriasis can produce thick scale and cracks, sometimes with changes on other skin or the nails. Moisture inside footwear may soften surrounding skin while friction repeatedly stresses the crack.

Wash gently, pat dry, and apply a plain moisturiser to intact dry skin. Emollient Therapy can help soften and support the skin barrier when recommended. Wear cushioned, well-fitting shoes and avoid walking barefoot over rough surfaces. Do not cut the thick edge, use harsh acids, or pull at loose skin. Keep any open fissure clean and covered with a suitable dressing.

Arrange a review when cracks are deep, recurrent, bleeding, or painful enough to alter your walking. Get prompt help for spreading redness, warmth, swelling, drainage, fever, or a wound that is not closing. If you have diabetes, reduced circulation, or reduced sensation, have a foot crack assessed rather than treating it aggressively at home.

Ask whether the fissures fit Atopic Dermatitis, Psoriasis, or mechanical dryness; which Emollient Therapy is appropriate; and whether infection or another foot condition needs to be ruled out.
