Athlete’s foot, medically known as tinea pedis, is a common fungal infection that primarily affects the feet but can also appear in other areas of the body. Although it is a treatable condition, many people delay seeking help due to embarrassment or lack of knowledge, which can worsen the infection and even facilitate its transmission to others.
In this article, you will understand what athlete’s foot is, how it develops, its characteristic symptoms, common myths, and the best ways to treat and prevent it.
What is athlete’s foot?
Athlete’s foot is an infection caused by dermatophyte fungi that feed on keratin present in the skin. These fungi thrive in warm, moist, and poorly ventilated environments — conditions commonly found on the feet, especially between the toes. It is highly contagious and can spread through direct contact with infected skin or contaminated surfaces such as gym floors, locker rooms, public showers, and swimming pools.
Causes and risk factors
The main cause of athlete’s foot is exposure to environments that promote fungal growth. Some risk factors that increase the likelihood of infection include:
Wearing closed shoes for long periods
Excessive sweating on the feet
Inadequate hygiene or improper drying between the toes
Walking barefoot in damp public places
Sharing socks, shoes, or towels
Weakened immune system
Although more common on the feet, athlete’s foot can also appear on the hands, elbows, and even underarms, especially in people who are in frequent contact with infected skin.
Symptoms of athlete’s foot
The most common signs include:
Intense itching, especially between the toes
Redness and peeling of the skin
Painful cracks or fissures
Burning or stinging sensation
Foul foot odor
Small fluid-filled blisters (in more severe cases)
If not properly treated, the infection can spread to other areas of the body or develop into secondary bacterial infections.
Can athlete’s foot be mistaken for other conditions?
Yes! Some skin conditions may be confused with athlete’s foot, such as dyshidrotic eczema, contact dermatitis, palmoplantar psoriasis, and even common skin tags (or acrochordons) — those small folds of skin that usually appear on the armpits and neck. However, skin tags have no relation to fungi or HPV, contrary to popular belief. That’s why a proper medical diagnosis is essential to avoid confusion and inappropriate use of medications.
Is athlete’s foot a sexually transmitted disease? Can it be transmitted through kissing?
❌ No. Although it is highly contagious through contact with infected skin or contaminated surfaces, athlete’s foot is not a sexually transmitted disease (STD). It is also not transmitted through kissing, as the fungus prefers warm, moist areas like the feet. However, it can be spread by sharing personal items like towels or shoes.
How to treat athlete’s foot
Treatment is simple but must be followed carefully. Key approaches include:
Antifungal creams and ointments, such as those containing clotrimazole, terbinafine, or miconazole
Antifungal powders to help keep the skin dry
Oral antifungal medications for more extensive or resistant cases
Proper foot hygiene: wash and dry thoroughly, especially between the toes
It’s important to complete the entire treatment course, even if symptoms disappear early, as the fungus may still be present on the skin.
Myths and facts about athlete’s foot
“Athlete’s foot only happens in the summer.”
Myth. While heat and humidity promote the infection, it can occur any time of year — even in winter — especially if feet are kept enclosed in tight shoes.
“It’s just a cosmetic issue.”
Myth. Although not a serious condition, athlete’s foot is an infection that can cause pain, discomfort, and complications if left untreated.
“Bleach helps cure athlete’s foot.”
Myth. Using harsh substances like bleach is not recommended and can worsen the skin lesions or cause burns.
How to prevent athlete’s foot
Prevention involves simple daily habits:
Keep your feet clean and dry
Dry well between the toes after bathing
Avoid walking barefoot in locker rooms, public showers, and pool areas
Wear flip-flops or shower shoes in such places
Choose cotton socks and change them daily
Rotate footwear to prevent moisture buildup
Never share shoes, towels, or socks
Let shoes air out after use
Conclusion
Athlete’s foot is a common, uncomfortable, and often overlooked condition. Knowing how to identify its symptoms, avoid risk factors, and seek proper treatment is essential to prevent complications. Debunking myths is also crucial to reduce stigma and promote prevention. If you’re unsure or have a persistent infection, consult a dermatologist for a proper evaluation and personalized guidance.
