Cracked heels, corns and warts: Summer foot problems you shouldn’t ignore

South African summers can be tough on feet, with hot pavement, going barefoot and wet conditions creating a breeding ground for various issues. Podiatrist Lynsey Hammond noted that foot care is often treated as a cosmetic issue, but it's actually about comfort, movement and everyday life. Podiatrist Dennis Rehbock offered advice on common summer foot problems and when to seek professional help.

Heat, humidity, and open footwear cause sweaty feet, which can lead to fungal infections like athlete's foot. Dry skin around the heels becomes more common when people wear sandals or go barefoot. Thickened skin, known as corns and calluses, often develop from ill-fitting shoes and require professional treatment if painful or persistent.

Cracked heels, or heel fissures, are a concern when they extend into the dermis, causing bleeding or infection. General advice is to file heels gently with an emery board and apply a urea-containing foot cream after bathing. Severe fissures should be treated by a podiatrist.

Despite occasional benefits, walking barefoot can pose risks for those not accustomed to it, especially if they have reduced sensation in their feet. Hot surfaces can burn feet, particularly for those with peripheral neuropathy. Plantar warts, caused by HPV, can be picked up in communal showers and pools, affecting children and teenagers. Over-the-counter treatments may help, but a podiatrist may use more advanced methods like electrocautery or cryosurgery.

People with diabetes face heightened risks due to poor circulation and nerve damage, which can lead to infections and ulcers. Regular podiatry check-ups and good foot care are crucial for diabetics. Warning signs that professional help is needed include changes in skin color, discolored nails, lesions, lumps, or unexplained changes. Always consult a professional when in doubt.
