What Does Athlete’s Foot Smell Like? Understanding the Unpleasant Odor and How to Stop It
Share
Ever slipped off your shoes and been greeted by a sour, funky cheese-like odor? You're not alone—and that smell might indicate a common condition known as athlete’s foot. Understanding this odor is crucial, not only to your comfort but also your foot health.

What is Athlete’s Foot?
Athlete’s foot, scientifically known as tinea pedis, is a common fungal infection that affects the skin on your feet. It typically thrives between your toes and can spread to your soles, causing redness, itching, peeling, and, yes, that notorious smell.
Simple Ways to Describe Athlete’s Foot Smell
The smell of athlete’s foot can vary significantly, but it's typically unpleasant and noticeable. It often resembles the smell of sour milk or cheese left out too long, which many people describe as funky or pungent. Others find the scent more reminiscent of dampness, like wet socks or shoes that have been left to sit for days. Sometimes the odor can even take on a musty characteristic, similar to mildew or a stale locker room.
Here’s a quick summary of common descriptions of athlete’s foot smell:

Why Does Athlete’s Foot Smell?
The smell associated with athlete's foot occurs due to fungi and bacteria breaking down sweat and dead skin cells on your feet. Dr. Kosta Antonopoulos, DPM, FACFAS, explains:
"The unpleasant smell comes when the perspiration isn’t allowed to evaporate... fungus thrives in warm, moist environments like what sweaty feet provide. So, if the bacteria on your foot isn’t what causes foot odor, fungus might be the culprit." (Central Park Sole)
This fungal breakdown releases volatile compounds, creating the strong odor you notice.
Why Does the Smell Vary?
The severity and type of smell can vary based on several factors:
- Type of fungus involved: Different fungal strains produce different odors.
- Hygiene practices: Poor foot hygiene intensifies odor.
-
Moisture levels: Excessive moisture from sweat increases fungal activity.
However, not everyone experiences odor. If your athlete’s foot is mild or in an early stage, you may have no noticeable smell.
Dr. Dendy Engelman, a board-certified dermatologist, explains:
"Athlete's foot can cause feet to smell sour or similar to a funky cheese, but some people may notice no smell at all." (Business Insider)
Those cases typically occur when fungal growth is minimal or caught early.
How to Prevent Athlete’s Foot and Reduce Odor
Complete the Treatment Cycle
Always follow treatment instructions thoroughly and complete your antifungal medication cycle, even if symptoms disappear earlier.
Keep Your Home Fungus-Free
Clean your showers and floors weekly and avoid walking barefoot, as fungi thrive on moist surfaces. Learn more about preventing athlete’s foot at home.
Rotate Your Shoes
Alternating shoes daily allows each pair sufficient time to dry completely, significantly reducing fungal growth potential.
Invest in Antifungal Socks
Regular socks don’t fully eliminate fungi—even after washing. At typical washing temperatures (around 86°F), more than 80% of fungi can survive. Antifungal socks use special materials to actively reduce fungal presence and prevent reinfections. Curious about the benefits? Check out our guide: Are antifungal socks worth it?

Understanding the unpleasant odor of athlete's foot and taking proactive steps—like wearing antifungal socks and maintaining proper foot hygiene—can drastically reduce your chances of dealing with athlete's foot. Incorporating these practices into your daily routine ensures you’re tackling both the odor and underlying fungal issues head-on.
