Key Takeaways
You train hard, you eat well, you take recovery seriously. And then you pick up a fungal infection from a locker room floor that takes weeks to clear.
Athlete's foot is the occupational hazard nobody talks about in fitness circles. But it affects a significant proportion of people who train regularly. The conditions inside gyms and changing rooms are almost perfectly calibrated for fungal transmission. If you are a runner, a gym regular, or play any sport involving shared facilities, you are in the highest-risk group and standard hygiene advice rarely goes far enough.
This guide is not about diagnosing or treating an athlete's foot. We have detailed guides on what an athlete's foot is and how to treat it already. This is specifically about prevention for people whose training environment puts them at elevated risk every session. From Imperial Feet's professional foot care range, trusted since 2001.
Why Gym-Goers and Runners Are at Higher Risk of Athlete's Foot
The three conditions that allow dermatophyte fungi to establish on skin are warmth, moisture, and time. Active people generate all three in abundance inside shoes, in changing rooms, and in shared shower spaces.
Athlete’s foot is not just bad luck — it is predictable and preventable by controlling moisture, protecting your feet in shared spaces, and maintaining proper hygiene.Important
Enclosed athletic footwear generates internal temperatures of 35–40°C with humidity levels above 70%. Both are well within the growth range of Trichophyton rubrum, the pathogen responsible for the majority of athlete's foot cases. Sports shoes worn for 60–90 minutes generate significantly more moisture than street shoes worn all day.
High-repetition skin microtrauma. The small abrasions caused by socks, shoe edges, and repeated foot strikes create microscopic entry points in the skin barrier that fungi exploit. Runners in particular develop these micro-abrasions between the toes and around the heel consistently.
Shared surfaces in gyms, locker rooms, and pool changing areas are the primary transmission vector. Fungal spores can survive on surfaces for months at room temperature. Every barefoot step on a shared floor is a potential contact event.
The combination of sweaty, microtraumatised feet making regular contact with spore-contaminated surfaces. Then, being sealed back into shoes is why active people get athlete's foot at significantly higher rates than the general population.
Quick Recap: What Is an Athlete's Foot?
Athlete's foot (tinea pedis) is a fungal skin infection caused by dermatophytes. The same family responsible for nail fungus and ringworm. It presents as itching, burning, or stinging between the toes, peeling or flaking skin on the soles, and in more advanced cases, blisters or skin that looks macerated and white between the toes.

The short version for prevention purposes: the fungus enters through damaged or softened skin, multiplies in warm and moist conditions, and spreads through direct contact with infected surfaces. Prevention means interrupting each of those three steps.
Locker Rooms & Showers: The Biggest Risk Zone for Foot Fungus
Communal changing areas and showers are where most athlete's foot infections begin not during the workout itself.
Warm, wet surfaces with high foot traffic and no individual cleaning between users are ideal fungal environments. The fungal spore load on a gym shower floor at peak hours is not trivial.
What to do:
-
Always wear flip-flops or shower sandals on any communal surface. Pool surrounds, gym showers, changing room floors, hotel bathroom floors. This single habit eliminates the primary transmission route. The flip-flops do not need to be expensive. They need to be there.
-
Never share towels. Towels that have been in contact with infected feet transfer spores directly. Personal towels only, washed at 60°C after every gym session.
-
Dry between your toes immediately after showering before putting on socks or shoes. The space between the fourth and fifth toe is where the athlete's foot consistently establishes first. Residual moisture in that space for even 30–60 minutes creates a hospitable environment. Pat each toe space individually.
-
Do not assume the showers at your gym are low-risk just because they look clean. Surface cleaning with standard detergents does not eliminate fungal spores effectively. The only protection that matters is between your bare foot and the surface.
Never put sweaty feet back into damp shoes after training. Carry spare socks, dry your feet completely (especially between toes), and disinfect your shoes regularly to break the fungal cycle.Pro tip
Shoe and Sock Choices That Help Prevent Athlete's Foot
Your footwear decision before the workout directly affects your fungal infection risk during and after it.
-
Breathable uppers matter. Leather, mesh, and canvas allow moisture vapour to escape. Fully synthetic materials like plastic, rubber and faux leather seal everything in. For gym training and running, choose shoes with ventilated mesh construction wherever the performance demands allow it.
-
Moisture-wicking socks. Wool (merino in particular) and technical athletic fabrics wick sweat away from the skin surface. Cotton absorbs moisture and holds it against the skin fine for low-intensity use, but in a 60-minute run or gym session, cotton socks become saturated and stay wet.
-
Change socks immediately after training. Do not drive home in wet socks. Carry a spare pair, change in the changing room or in your car. The window between removing your shoes and putting on dry socks is when sweated, microtraumatised skin is most vulnerable.
-
Rotate your training shoes. Each pair needs 24–48 hours to fully dry between sessions. Wearing the same pair to back-to-back training days means putting your feet back into a still-damp interior which is essentially the same as a petri dish with laces. If you train daily, own two pairs.
Best shoes to prevent athlete's foot: The specific model matters less than the material. Mesh uppers, removable moisture-wicking insoles, and enough room in the toe box that toes are not compressed together.
Post-Workout Foot Care Routine | Build These Habits
The 5 minutes after training finishes are the most important window for fungal prevention. Most people spend them on their phone in the changing room. Spend them on this instead.
-
Remove shoes as soon as possible after training ends. Do not keep them on for the drive home or the post-workout coffee.
-
Wash feet thoroughly with soap in the shower. Specifically between every toe, not just letting water run over the feet.
-
Dry immediately and completely. As above, between each toe space. A dry, clean towel, personal use only.
-
Apply a protective foot balm or antifungal daily moisturiser before putting on clean, dry socks. Foot Balm Green contains Piroctone Olamine. A broad-spectrum antifungal and antibacterial active alongside Aloe Vera and Ginseng. Applied after training, it conditions and protects the skin at exactly the point when it is most vulnerable.
-
Put on clean, dry socks. Not the ones you trained in.
This routine takes four minutes. It is the single most effective thing most active people are not doing.
How to Disinfect Gym Shoes and Gear
This is the step almost everyone skips and one of the main reasons an athlete's foot keeps returning even when people treat it.
Fungal spores survive inside shoes for up to 12 months at room temperature. If you have had an athlete's foot and treated it successfully, the spores from that infection may still be living in your training shoes. The next time you put them on after a shower, you reinfect yourself.
-
Disinfect gym shoes with our antifungal shoe spray. Imperial Feet Anti-Fungal Shoe & Sock Spray. Spray 6–8 times inside each shoe after every session. Allow to dry before next use. The Benzalkonium Chloride, Camphor, and Zinc Ricinoleate combination kills fungal spores on contact inside shoe linings and fabric.
-
Spray your socks too before putting them in the wash, or before wearing freshly washed ones. Wash socks at 60°C minimum to kill spores in the fabric.
-
Replace insoles every 3–6 months if you train regularly. Insoles absorb the highest concentration of sweat and skin debris in the shoe and cannot be fully sanitised over time.
Gym bag hygiene: damp kit left in a closed gym bag creates an ideal fungal environment. Take everything out after training, air the bag, and wash kit promptly.
Signs You're Getting Athlete's Foot | Catch It Early
Prevention first, but if it has already started, catching it early makes treatment significantly faster.
Early signs: mild itching or tingling between the toes (especially fourth and fifth), slightly white or softened skin in the toe webs, a faint burning sensation after removing shoes.
At this stage, a targeted antifungal treatment applied consistently for 5–7 days typically resolves the infection before it spreads. Do not wait for visible peeling or blistering to confirm it and act.

Frequently Asked Questions | Athlete's Foot Prevention for Gym-Goers
Should runners wear socks in gym showers?
No, but flip-flops are far more effective than socks on wet surfaces. Socks become saturated and still allow direct contact between the sock fabric (which may already carry spores from training) and the shower floor. Flip-flops or shower sandals provide a complete physical barrier. Keep a pair specifically for gym use.
What are the best shoes to prevent an athlete's foot?
Breathable mesh uppers are the most important factor. They allow moisture vapour to escape during training, reducing the internal humidity that enables fungal growth. Combined with moisture-wicking socks, a ventilated shoe significantly reduces the risk compared to synthetic alternatives. Rotating between two pairs so each dries fully between sessions matters as much as the material choice.
How to prevent an athlete's foot in the gym?
Spray the inside of each shoe with an antifungal shoe spray 6–8 sprays per shoe, covering the toe box and insole. Allow to air-dry before next use. Use after every training session during and after any active infection, and 2–3 times per week for ongoing prevention. See the Anti-Fungal Shoe & Sock Spray for the specific formula used in professional settings.
Is an athlete's foot the same as just sweaty feet?
No, though they can look similar in early stages. Sweaty feet produce damp skin but no itching, peeling, or redness. Athlete's foot involves actual fungal colonisation; itching is the key differentiator. If the skin between your toes is itching or burning, not just damp, treat it as an athlete's foot rather than just a hygiene issue. Sweaty feet increase the risk of an athlete's foot but are not the same condition.
Can I still train if I have an athlete's foot?
Yes, with precautions. Continue wearing flip-flops in communal areas, change socks immediately after training, apply antifungal treatment consistently morning and evening, and spray your shoes after every session. Avoid sharing any footwear or towels. If the infection is spreading rapidly or involves broken skin, take a few days off high-intensity training that generates heavy sweat until it has settled.
