Athlete Foot
Also known as Tinea pedis, Fungal foot infection
This article is general health information for the selected condition. It is not a diagnosis and does not replace clinical judgement. If you have questions or need treatment advice, please consult a qualified healthcare professional.
What is athlete foot?
Athlete foot is a fungal skin infection, usually starting in the moist skin between the toes. It is easily treated with antifungal cream but returns readily if the feet stay damp. It matters beyond the itch because the cracked skin is a common entry point for bacteria causing cellulitis, particularly in people with diabetes or leg swelling.
Causes
- Dermatophyte fungi thriving in warm moist skin
- Walking barefoot in changing rooms and pools
- Sweaty feet in occlusive footwear
- Sharing towels, socks or shoes
- Not drying between the toes
Symptoms
- Itchy, flaky or scaly skin between the toes
- Cracked or peeling skin
- Redness and soreness
- Stinging or burning
- Blisters in some cases
- Thickened discoloured toenails if it spreads
Risk factors
- Frequent use of communal showers or pools
- Wearing trainers or boots for long periods
- Excessive foot sweating
- Diabetes
- Weakened immune system
- Previous episodes
Diagnosis
- Clinical diagnosis from appearance and distribution
- Skin scraping for microscopy where the diagnosis is unclear
- Nail clipping sample if nails are involved
- Assessment for cellulitis if the foot is red and swollen
Treatment
- Topical antifungal cream such as terbinafine or clotrimazole
- Continue treatment for one to two weeks after skin clears
- Antifungal powder in shoes to reduce recurrence
- Oral antifungal for extensive or resistant infection
- Separate longer treatment if toenails are infected
Self care
- Dry thoroughly between the toes after washing
- Change socks daily and choose breathable materials
- Alternate shoes so each pair dries out fully
- Wear flip flops in communal showers and changing rooms
- Do not share towels, socks or footwear
- Keep using the cream for the full course, not just until itching stops
When to see a doctor
Book an appointment if:
- No improvement after two weeks of antifungal cream
- The infection keeps returning
- Toenails become thick, crumbly or discoloured
- You have diabetes and any foot skin problem
- The foot becomes red, hot, swollen or painful
- Weakened immune system
Some symptoms need emergency care rather than an appointment. See the warning signs listed above.
Prevention
- Dry feet properly, particularly between the toes
- Wear sandals in communal wet areas
- Rotate footwear and use antifungal powder if prone
- Change socks daily and after exercise
- Treat infected household members at the same time
Outlook
Athlete foot clears within two to four weeks of proper antifungal treatment, but recurrence is very common if feet stay damp or the full course is not completed. Nail involvement is more stubborn and needs months of treatment. Treating it properly is worthwhile because it reduces the risk of recurrent cellulitis.
Common questions
Why does it keep coming back?
Usually because treatment stopped as soon as the itch settled, leaving fungus behind, or because the feet remain damp in the same shoes. Continue cream for one to two weeks after the skin looks normal and treat the footwear as well.
Why does it matter if I have diabetes?
Cracked skin between the toes lets bacteria in, and reduced sensation means an infection may go unnoticed until it is advanced. Any foot skin problem with diabetes deserves prompt attention.
