- The infection spreads easily in warm, moist environments like gym locker rooms, public pools, and shared showers.
- Risk factors include sweaty feet, occlusive footwear, and close contact with contaminated surfaces.

What Is Athlete's Foot?
Athlete's foot — known medically as tinea pedis — is one of the most common fungal skin infections in the world. Despite its name, it doesn't only affect athletes. Anyone can develop it, regardless of age or activity level.
The infection is caused by a group of fungi called dermatophytes, which thrive in warm, damp environments. These organisms feed on the keratin found in skin, hair, and nails, making the feet — often confined in warm socks and shoes — an ideal breeding ground.
Athlete's foot affects an estimated 15 to 25 percent of people at any given time, making it one of the most prevalent skin conditions treated by both dermatologists and podiatrists.
Early Warning Signs of Athlete's Foot
Many people with athlete's foot initially mistake it for dry skin, eczema, or minor irritation. Recognizing the early signs is key to treating it quickly before it spreads.
Common Athlete's Foot Symptoms
- Itching, stinging, or burning sensations between the toes or on the soles of the feet
- Peeling, scaling, or flaking skin — particularly between the toes
- Redness, inflammation, or raw-looking skin
- Blisters that may ooze or crust over
- Dry, cracking skin along the heel or sides of the foot
- An unpleasant or musty odor
How to Tell Athlete's Foot Apart from Dry Skin
| Feature | Athlete's Foot | Dry Skin |
|---|---|---|
| Location | Typically between toes, soles | Anywhere on the foot, often heels |
| Itching | Intense, often worse after shoes removed | Mild or absent |
| Skin appearance | Peeling, scaling, or blistered | Rough, flaking, no blisters |
| Spreads over time | Yes, without treatment | Generally does not spread |
| Responds to moisturizer alone | No | Often yes |
Athlete's Foot Causes: How Does the Infection Develop?
Athlete's foot is caused by direct contact with the fungi responsible for the infection, most commonly Trichophyton rubrum. These fungi survive for extended periods on surfaces and in environments where people walk barefoot.
Common Places Where Athlete's Foot Spreads
The infection spreads most readily in locations where:
- Warm, moist surfaces are shared — locker rooms, swimming pool decks, communal showers, and saunas
- Shared footwear, socks, or towels create direct contact between an infected person and others
- Personal footwear traps heat and moisture, creating a favorable environment for fungal growth
Itchy Feet Fungus Risk Factors
Certain factors increase a person's likelihood of developing athlete's foot:
- Sweaty feet (hyperhidrosis): Excess moisture on the skin creates the perfect fungal environment. Lake Erie Podiatry also treats hyperhidrosis of the feet as part of its broader foot care services.
- Occlusive footwear: Shoes made of non-breathable materials trap heat and moisture.
- Walking barefoot in public areas: Pools, gyms, and shared bathrooms are high-risk zones.
- A weakened immune system: Those with diabetes or other immune-compromising conditions face higher risk.
- Sharing personal items: Towels, socks, or shoes used by an infected person can transmit the fungi.
What Happens If Athlete's Foot Goes Untreated?
Left untreated, athlete's foot does not typically resolve on its own — and the longer it persists, the more likely it is to cause complications.
Untreated infections can:
- Spread to the toenails, causing a separate condition called onychomycosis (fungal toenail infection), which is more difficult to treat
- Spread to the hands, particularly if the infected foot is scratched and then the hands touch other surfaces
- Cause bacterial secondary infections, especially if the skin becomes cracked or blistered and bacteria enter through the broken skin
- Lead to cellulitis, a potentially serious skin infection that requires medical treatment
Athlete's Foot Treatment Options
Treatment for athlete's foot typically begins with antifungal medications. The appropriate approach depends on the severity and location of the infection.
Over-the-Counter Options
Mild to moderate athlete's foot often responds well to topical antifungal creams, sprays, or powders available without a prescription. These products typically need to be applied consistently for two to four weeks, even after symptoms improve, to fully eliminate the fungus.
When to See a Podiatrist
Over-the-counter treatments don't always work — especially when the infection has spread to the toenails, recurs frequently, or does not improve after a few weeks of treatment. A podiatrist can:
- Confirm the diagnosis and rule out other conditions like eczema or psoriasis
- Prescribe stronger topical or oral antifungal medications
- Treat any secondary bacterial infection
- Address underlying issues like excessive foot sweating that contribute to recurrence
At Lake Erie Podiatry, toenail fungus is among the foot pain and skin conditions treated by Dr. Michael Ruiz, DPM, who brings over 20 years of podiatric experience to every patient visit.
Preventing Athlete's Foot: Practical Tips
Prevention is straightforward but requires consistent habits, particularly for those who frequent gyms, pools, or locker rooms.
- Wear sandals or water shoes in communal showers, locker rooms, and pool areas
- Change your socks daily — and more often if your feet sweat heavily
- Choose breathable footwear made of natural materials like leather or mesh
- Dry your feet thoroughly after bathing, paying close attention to the spaces between your toes
- Avoid sharing towels, socks, or footwear with others
- Rotate your shoes to allow them to dry out completely between uses
- Use antifungal powder in your shoes if you are prone to sweaty feet

Frequently Asked Questions
What is athlete's foot?
Athlete's foot is a fungal skin infection caused by dermatophytes — organisms that thrive in warm, moist environments. It most commonly appears between the toes and on the soles of the feet, causing itching, peeling, redness, and in some cases, blistering.
What are the early symptoms of athlete's foot?
The earliest signs of athlete's foot include mild itching or stinging between the toes, along with slight scaling or peeling of the skin. These symptoms are easy to overlook or mistake for dry skin, which is why awareness of the other associated signs — like redness, blisters, and burning — is important.
What are the most common athlete's foot causes?
Athlete's foot is caused by direct contact with the fungi responsible for the infection, typically in warm, humid shared spaces like locker rooms and public pools. Walking barefoot in these areas, wearing non-breathable shoes, and having chronically sweaty feet all increase the risk.
Can itchy feet fungus spread to other parts of the body?
Yes. Without treatment, athlete's foot can spread to the toenails, hands, and groin. If the skin becomes cracked or broken, bacteria can also enter and cause a secondary infection. Prompt treatment reduces the risk of these complications.
Is peeling skin between toes always athlete's foot?
Not necessarily — peeling skin between the toes can also result from contact dermatitis, eczema, or excessive moisture. However, if the peeling is accompanied by itching, burning, or redness, athlete's foot is a strong possibility. A podiatrist can confirm the diagnosis and recommend the most effective treatment.
