It can sometimes causes fluid-filled blisters.
Causes of athlete's foot
You can catch athlete's foot from other people with the infection.
You can get it by:
- walking barefoot in places where someone else has athlete's foot – especially changing rooms and showers
- touching the affected skin of someone with athlete's foot
You're more likely to get it if you have wet or sweaty feet, or if the skin on your feet is damaged.
Treatment for athlete's foot

When to see a GP
See a GP if:
- treatments from a pharmacy don't work
- you're in a lot of discomfort
- your foot is red, hot and painful – this could be a more serious infection
- you have diabetes – foot problems can be more serious if you have diabetes
- you have a weakened immune system. For example, you've had an organ transplant or are having chemotherapy
Your GP may take a small sample of your affected skin cells.
The sample will be sent to a laboratory to be tested in order to identify the exact type of fungi that is causing your infection. This will help them to prescribe the most appropriate treatment.
They may also refer you to a skin specialist called a dermatologist for more tests and treatment if needed. Your GP may also prescribe a steroid cream and anti-fungal tablets.
Self-management of athlete's foot
To treat athlete's foot and prevent it returning:
Dry your feet after washing them, particularly between your toes. Dab them dry rather than rubbing them.
Use a separate towel for your feet and wash it regularly.
Take your shoes off when at home.
Wear clean socks every day. Cotton socks are best.
Do not scratch affected skin – this can spread it to other parts of your body
Do not walk around barefoot – wear flip-flops in places like changing rooms and showers
Do not share towels, socks or shoes with other people
Do not wear shoes that make your feet hot and sweaty
Keep following this advice after finishing treatment. This will help stop athlete's foot coming back.
