Despite its name, athlete’s foot does not require you to be an athlete. This condition mostly affects men. It can be more common in some people, while others can resist it easily. The fungus that grows on the skin’s top layer or inside of it causes athlete’s foot. It thrives in warm, humid conditions, so the area between the toes is ideal for spreading and surviving.
In fact, as of 2025, athlete’s foot—medically known as tinea pedis—remains one of the most prevalent superficial fungal infections worldwide, affecting an estimated 15–25% of the adult population. The condition’s incidence has seen a notable uptick recently, driven by evolving lifestyles, increased participation in fitness activities, and lingering effects from the post-pandemic era, where heightened home workouts and shared gym spaces contributed to a 4.8% compound annual growth rate (CAGR) in the global athlete’s foot market from 2023 to 2025. This surge illustrates the value of understanding not just how you get athlete’s foot, but also how to prevent and treat it effectively in today’s fast-paced world.
Diagnosing Athlete’s Foot?
Tinea pedis, often known as athlete’s foot, is a fungal infection that affects the feet. As a result, blisters, stinging, and burning can occur on the feet and between the toes. Trichophyton rubrum, Epidermophyton floccosum, and Trichophyton mentagrophytes are just a few of the fungi that may be found in nature. Although the illness is not life-threatening, it can be quite unpleasant.
Diagnosis typically begins with a clinical examination by a healthcare provider, who will assess the characteristic symptoms like scaling, itching, and fissuring. For confirmation, especially in atypical cases, a potassium hydroxide (KOH) preparation or fungal culture may be performed. In 2025, advancements in dermatology have introduced point-of-care molecular testing kits that can identify the specific fungal strain within minutes, improving accuracy and speeding up treatment initiation. This is particularly useful in high-risk groups, such as military personnel, where prevalence reaches 17% due to shared living quarters and rigorous physical demands. Early diagnosis is key, as untreated tinea pedis can lead to secondary bacterial infections or spread to other areas like the nails (onychomycosis), affecting up to 50% of chronic cases.
What Causes Athlete’s Foot
As we’ve already stated, an athlete’s feet are caused by a fungal infection. The following are secondary causes:
- Damp socks
- Tight shoes
- Humidity
- Contact skin-to-skin with infected persons
- The infected person may share shoes, socks, and towels with others.
- Weak immune system
These factors create the perfect microenvironment for dermatophytes—fungi that feed on keratin in the skin—to proliferate. In humid climates or during sweaty activities, moisture trapped in footwear can increase risk by up to 30%, according to a 2024 epidemiological study. Additionally, individuals with compromised immunity, such as those with diabetes or undergoing chemotherapy, face a 2-3 times higher susceptibility. Post-pandemic shifts, including more indoor fitness routines without proper ventilation, have exacerbated this, contributing to a 5-7% rise in reported cases among urban adults in 2024-2025.
Other emerging contributors include the widespread use of synthetic, non-breathable athletic wear and the resurgence of communal spaces like gyms, where indirect contact via floors or equipment spreads spores. For children, school locker rooms and sports programs have led to prevalence rates as high as 15.6% in some regions, suggesting that there must be age-specific awareness.
Is the Foot of an Athlete Contagious?
It has the potential to spread quickly to the hands. Tinea manuum, often known as itching, is a skin condition. It can happen if you put your feet in contact with diseased skin and don’t wash them afterward. This might result in a dry, itchy, and reddish region on the skin.
If you touch contaminated regions on your foot or other parts of your body, you might transfer the infection to others. It is critical to treat athlete’s foot infections as soon as possible and wash your hands after contact with the infected region.
Athletes’ feet can be contracted by walking barefoot in moist places such as the floors surrounding swimming pools, showers, and gyms, or by exchanging towels, mats, and other footwear. If you go out in public, wear flip-flops, shower shoes, or swim shoes to keep the sickness from spreading. Unless the feet are kept dry and covered with socks, it is pretty easy to get the disease.
Yes, athlete’s foot is highly contagious, with spores surviving on surfaces for weeks in damp environments. Transmission occurs via direct contact or fomites (inanimate objects like towels), and autoinoculation—spreading from feet to hands or groin—is common in 20-30% of cases. In shared households or sports teams, outbreaks can affect multiple individuals if hygiene protocols lapse. Recent 2025 guidelines from the World Health Organization emphasize isolating contaminated items and using antifungal disinfectants on floors to curb spread, especially in high-density settings like military barracks or fitness centers.
What Are the Signs of Athlete’s Foot?
- Skin that is flaky and scaly
- The skin between the toes can be whitened and softened.
- The skin of the feet can become crusty, irritated, and fissured.
- Itching, burning, and stinging between your toes.
- Itchy blisters and vesicles on the soles of the feet.
- Excessive dry skin.
- The feet are red.
- Toenails that are thick, discolored, and ragged.
- If severe conditions are present, bleeding may occur from cracked skin.

These symptoms often manifest interdigitally (between toes) in mild cases but can progress to moccasin-type (sole involvement) or vesicular patterns in more severe infections. In 2025, dermatologists note a rise in atypical presentations, such as hyperkeratotic variants resistant to standard topicals, linked to evolving fungal strains. Pain from fissures can impair mobility, particularly in older adults or those with comorbidities, where symptoms overlap with conditions like eczema or psoriasis, necessitating differential diagnosis.
How Can I Tell If I Have Athlete’s Foot?
Although it is easy to tell if you have athlete’s feet from your symptoms, your doctor can diagnose the condition for any person who is concerned. He may request a skin test to determine if a fungal infection is the cause.
The most common skin lesion potassium-hydroxide test involves your doctor removing a small amount of infected skin from the area and putting it in potassium hydroxide (KOH). The KOH kills normal cells but leaves the fungal cells unaffected, making them easy to view under a microscope.
Beyond the KOH test, options now include Wood’s lamp examination for fluorescing fungi or PCR-based assays for rapid identification. Self-assessment tools, like apps that analyze foot photos against AI-trained models, have gained popularity in 2025, boasting 85% accuracy for preliminary screening, though professional confirmation remains essential.
Treatment Options for Athlete’s Foot in 2025
While the original article focused on causes and symptoms, effective management is crucial for resolution and prevention of recurrence, which affects 40-50% of patients without proper follow-up. Topical antifungals remain first-line: Allylamines like terbinafine (Lamisil), applied twice daily for 1-2 weeks, cure 70-80% of cases, outperforming azoles in speed. For hyperkeratotic types, newer agents like 1% luliconazole, applied for up to three months, show superior efficacy in recent trials, reducing symptoms by 90%.
Over-the-counter options include tolnaftate powders, but a Phase 2 trial in late 2025 is evaluating a novel tolnaftate stick formulation for easier application in active lifestyles. Severe or refractory cases may require oral itraconazole or fluconazole for 2-4 weeks, monitored for liver function. Home remedies like tea tree oil or vinegar soaks lack robust evidence and may irritate skin, per Cleveland Clinic’s 2025 advisory—stick to proven therapies.
Combination therapy, pairing topicals with keratolytics (e.g., urea creams) to soften thick skin, is increasingly recommended. The tinea pedis treatment market, valued at USD 1.3 billion in 2023, is projected to grow at 4.3% CAGR through 2032, reflecting demand for innovative, user-friendly products like antifungal socks and sprays.
Prevention Strategies: Staying One Step Ahead
Preventing athlete’s foot is simpler than treating it. Beyond the basics, incorporate daily habits like rotating shoes to allow drying (24-48 hours) and using moisture-wicking socks made from bamboo or merino wool, which reduce fungal growth by 50% compared to cotton. Antifungal foot powders in shoes and treating footwear with sprays weekly can eliminate spores.
In communal areas, flip-flops are non-negotiable. For families, designate separate towels and launder them in hot water (60°C+) with antifungal additives. Post-pandemic, enhanced hygiene from remote work has lowered some risks, but rebound gym attendance has spiked cases—aim for breathable environments and post-workout foot soaks in diluted antifungal solutions.
When to See a Doctor
Seek medical attention if symptoms persist beyond two weeks of OTC treatment or spread to nails or groins, or if you have diabetes, as uncontrolled tinea pedis raises infection risks by threefold. Red flags include fever, pus, or swelling indicating cellulitis.
