Athlete’s foot is a common skin infection of the feet caused by a fungus. The fungus causes an itchy, red or flaky rash between the toes or soles of the feet that can become cracked and painful. Athlete’s foot is also known as tinea pedis, which means ‘tinea of the foot’.

Although the name suggests otherwise, you don’t have to be an athlete to develop athlete’s foot – the fungus can infect anyone.

The fungus grows in areas that are warm and humid, particularly the skin between the toes and sometimes the soles of the feet.

Fungal infections of the feet have affected people for centuries, with the condition first described in the late 1800s and early 1900s. They have become more common over the last several hundred years due to the increased use of shoes that don’t allow the feet to breathe, which creates an ideal environment for the fungus to grow.

Causes of athlete’s foot

There are a number of species of fungus that can cause athlete’s foot. The most common species (called Trichophyton) can be found in warm or humid environments, which includes many places in Australia. Wearing poorly ventilated shoes and sweaty socks can allow the feet to become a breeding ground for the fungus.

The fungus can spread from person to person through walking barefoot on contaminated floors in places like shared showers, changing rooms, or swimming pools. The fungus can also survive in socks and clothing, or on used towels.

Athlete’s foot symptoms

The symptoms of athlete’s foot affect the feet, particularly the toes. Any toe can be affected, but the skin between the outermost toes (the fourth and fifth toes) is most commonly involved. Fungal infections can sometimes spread to the soles of the feet.

Symptoms of athlete’s foot can include:

Symptoms in advanced stages

For most people, the condition is an uncomfortable but temporary nuisance. However, if athlete’s foot is not treated, the condition may become more serious.

In advanced stages, some of the following symptoms may occur:

Because athlete’s foot can lead to cracks in the skin, bacteria are able to enter the skin and cause bacterial infections. The skin may become severely inflamed (called cellulitis), although this is more common in particular people, such as the elderly and people with diabetes, weakened immune systems, or chronically swollen legs, or those who have had veins removed from their legs (such as for heart bypass surgery).

Other sites of fungal infections

Fungal infections can also affect other areas of the body where conditions are warm and humid, such as the groin (‘jock itch’), the scalp or skin folds (such as under the breasts).

Risk factors for athlete’s foot

There are a number of risk factors for athlete’s foot including:

Diagnosis of athlete’s foot

Athlete’s foot is usually diagnosed on the basis of its typical symptoms. However, tests may be necessary in some cases if your doctor is uncertain about the cause of foot problems, or to rule out other skin conditions (such as psoriasis or dermatitis).

Tests can include:

Basic treatments for athlete’s foot

There are a number of simple steps you can take to help treat (and prevent) athlete’s foot:

Medical treatments for athlete’s foot

Antifungal treatments help to relieve symptoms and clear the infection. These treatments can include:

Antifungal creams, gels, ointments, sprays or powders – these medicines are available over the counter from pharmacies or by prescription and are applied to the feet and in between the toes. It’s important to use these medicines according to their instructions:

Antifungal tablets – your doctor may prescribe a course of antifungal tablets if you have severe athlete’s foot that covers a large area, or if it has not responded to antifungal products applied to the skin. Tablets might also be recommended if the fungal infection has spread to the toenails.

When should I consult my doctor?

Early treatment can ensure athlete’s foot is correctly diagnosed and treated to prevent complications. For most people, keeping feet clean and dry – plus applying antifungal products to the skin – will be enough to clear the infection. However, you should see your doctor if your symptoms don’t get better despite treatment, or if there is any redness, increased swelling or bleeding. You should also seek medical advice if you have any of the underlying health conditions described earlier (e.g. diabetes, a weak immune system or chronic swelling of the legs).
