Athlete's foot

Tinea pedis
Medically reviewed · Hottinger Podologie, ZurichUpdated: July 2026

Athlete's foot (tinea pedis) is a contagious fungal infection of the skin of the feet, most often between the toes. The skin itches, reddens, flakes or turns whitish and soggy. Untreated, the fungus likes to spread to the nails, where it becomes far more stubborn.

Common causes and risks
  • A warm, moist climate in closed shoes
  • Barefoot zones: pools, saunas, changing rooms, hotel carpets
  • Sweaty feet, narrow spaces between the toes
  • Diabetes and circulatory disorders increase the risk
What you can do yourself

Dry your feet thoroughly after washing, especially between the toes. Change socks daily and wash them hot, alternate and air your shoes, wear bathing shoes in barefoot zones. Over-the-counter antifungals work well when used consistently; continue for a few days after symptoms fade.

When to see a podiatrist

If the areas weep, hurt or fail to heal, if nails are discoloured as well, and always with diabetes: softened, cracked skin between the toes is a classic entry point for bacteria. We assess the findings, care for the skin and advise on preventing relapse.

Did you know?

Fungi love exactly the climate that reigns inside shoes: warm, moist, dark. The most effective therapy therefore starts not in the tube but with drying the spaces between your toes.
