Athlete's Foot (Tinea Pedis) in Martial Arts

Train barefoot on shared mats for a few years, like I have, and athlete's foot stops being bad luck and starts being an occupational hazard. It's common, usually minor, and very manageable — but it's also easy to pass around and easy to let drag on. Here's the plain-English version: general information, not medical advice, and not about any product we sell, fact-checked against trusted sources and the doctors we work with.

What it is

Athlete's foot (tinea pedis) is a common fungal infection of the feet, in the same dermatophyte family as ringworm and jock itch. The NHS describes itchy, scaly and sometimes cracked or sore skin, classically between the toes, though it can affect the soles and sides of the feet too (NHS: Athlete's foot). The same fungus can travel to other warm, damp areas, which is how a foot problem becomes a groin problem if you're not careful with the order you dry and dress in.

Why martial artists are prone

Warm, damp, communal floors plus barefoot training are close to ideal conditions for the fungi behind it. The walk from the mat to the showers to the changing room is a tour of exactly the surfaces it likes. The mats themselves are a factor, which is part of why clubs clean them — see how to clean and disinfect training mats — but your own routine off the mat matters just as much.

How to recognise it

The familiar version is itchy, flaky, sometimes cracked skin between the toes — often starting in the gap between the smallest toes — that can sting or feel raw. It can also show up as dry, scaly patches on the soles and sides of the feet, or as small blisters. The itch and the between-the-toes flaking are the usual giveaways, but a pharmacist or GP can confirm it, since plain dry skin and other conditions can look similar to the untrained eye.

Habits that help

• Wash and, crucially, dry your feet thoroughly after training, especially between the toes — damp skin is the whole game. There's a full routine in the post-training shower routine.
• Wear clean, dry socks, and let trainers air out and dry between uses; rotating footwear helps.
• Consider footwear off the mat in communal areas like changing rooms and showers.
• Don't share towels, and dry your feet last so you're not carrying anything from your feet to the rest of your body.

What to do if you get it

A pharmacist is a sensible first stop and can advise on managing a typical, mild case. Keep up the drying-and-clean-socks basics while it clears, because re-exposing damp feet to the same conditions is exactly how it lingers or comes straight back. If a training partner has it, the shared-mat reality means the room's general hygiene matters too, not just yours.

Don't pass it around

Active, flaking athlete's foot on a shared mat isn't ideal for anyone. You usually don't need to stop training for a mild case, but keep your feet clean and dry, cover any broken or weeping skin as advised, and get it looked at if you're unsure. The same courtesy applies as with any skin issue: if in doubt, ask a coach.

Common questions

Can I train with athlete's foot?

A mild case usually doesn't mean stopping, but you're training barefoot on a shared surface, so keep your feet clean and dry, cover broken or weeping skin as advised, and get it sorted rather than letting it linger. If it's badly cracked or weeping, it's worth checking with your coach and ideally a pharmacist first.

Why does it keep coming back?

Usually because the conditions never change: damp feet, trainers that don't dry out, or re-exposure on a communal floor. The fix is rarely one thing applied once — it's the boring drying-and-clean-socks routine kept up consistently, plus airing footwear between sessions and not living in the same damp trainers.

Can the mats give it to me, or just other people?

Both. Shared, warm, damp floors are part of how the fungus spreads, which is why mat cleaning matters — but you can pick it up from surfaces as well as from other people. That's why the prevention habits work on both ends: clean mats from the club, and dry, clean feet from you.

When to see a doctor

Speak to a pharmacist or GP if foot skin is cracked, painful, weeping, spreading or simply not settling with the basics. Take extra care and seek advice sooner if you're diabetic or have circulation problems, as foot issues need closer attention in those cases. Anything that looks infected — increasingly red, hot and painful — is also worth getting checked promptly.
