Cracked Heel Infection: What to Know

Dry, thick heel skin may split under pressure, creating a small opening. Infection becomes more concerning when the surrounding skin grows red or hot, the swelling increases, pain changes from soreness to throbbing, or fluid and pus appear. A crust alone does not confirm infection. Fungal skin problems such as Athlete's Foot can also cause scaling and fissures, while simple Dry Skin may crack without infection. Look at the whole foot, including between the toes, and notice whether the area is spreading or becoming harder to walk on.

Gently rinse the area with clean water, pat it dry, and cover an open fissure with a clean dressing that does not stick to the wound. Avoid picking the edge, cutting thick skin, or applying strong acids to broken skin. Keep socks clean and change them when damp; choose footwear that reduces rubbing at the heel. Once the skin is closed and infection is not suspected, regular Emollient Therapy can soften surrounding dryness. Do not share towels or footwear if a fungal rash is possible.

Arrange prompt medical care if redness, heat, swelling, discharge, or pain is increasing, or if a red area is extending beyond the crack. Seek urgent help for fever, feeling faint or very unwell, rapidly spreading redness, or severe difficulty walking. Get advice earlier if you have diabetes, reduced sensation, poor circulation, or a weakened immune system, because a small heel wound may need closer assessment.

Ask whether the changes fit bacterial infection, fungal disease, or inflammation; whether the wound needs a specific dressing; and which moisturiser is suitable near the affected skin. Mention when the crack began, any drainage, recent foot treatments, and health conditions that affect healing.
