What should you know about thickened skin under foot?

The sole bears repeated pressure, so calluses and corns can form on weight-bearing points or where footwear rubs. Dry skin may split, particularly around the heel, and repeated scratching can create a thicker, leathery surface. Itch and scale between or beneath the toes can suggest a fungal problem, while Atopic Dermatitis can also cause itchy, inflamed, thickened skin. A wart, foreign body, pressure imbalance, or another condition can resemble a callus. The exact site and surface matter when choosing treatment.

Wash the foot gently and dry it carefully, including between the toes. Apply moisturiser to dry, intact sole skin, but avoid leaving heavy product between the toes. Wear well-fitting shoes and clean socks, and change footwear if a seam or hard edge is causing pressure. Do not cut, burn, or aggressively file the thickened area. If walking is painful or the skin is cracked, arrange professional advice before using medicated pads or strong acids.

Seek prompt care for warmth, spreading redness, swelling, pus, bleeding, severe pain, or a foot wound that is not closing. Have a new dark or irregular spot, a rapidly enlarging patch, numbness, or a persistent ulcer assessed. If you have diabetes, poor circulation, reduced sensation, or immune suppression, contact a clinician early rather than treating a break in the skin yourself.

Ask whether the area is a callus, corn, wart, dermatitis, infection, or another issue; whether pressure distribution or footwear is involved; and which product is safe for your skin. Describe pain while walking, itch, scale, odour, cracks, drainage, and any change in footwear or activity.
