If you’ve ever found yourself discreetly scratching your foot against the carpet, or trying to relieve the itch in your trainers mid-workout, you’ll know that athlete’s foot is no joke. The peeling skin, redness, and smell aren’t great... but it’s the itch that really drives people mad.
So, why does athlete’s foot itch so much? And more importantly, how do you stop it without resorting to desperate “scratch it with a fork” tactics? Let’s dig in.
What Is Athlete’s Foot?
Athlete’s foot, or tinea pedis, is a common fungal infection caused by dermatophytes - microscopic fungi that love warm, damp places. Think sweaty trainers after your gym session, or between your toes after a long run. Perfect fungal Airbnb.
These fungi feed on keratin, a protein in your skin, hair and nails. As they break down your skin barrier, your body’s immune system leaps into action, releasing chemicals like histamines. These histamines inflame the skin and irritate your nerve endings, which is why your brain screams, “SCRATCH!” .
The British Association of Dermatologists explains that this inflammatory response is what leads to redness, scaling, and, yes, the itch.
Why Does It Itch So Much?
-
Immune response: Your body detects fungi and floods the area with histamines, which make nerve endings fire itch signals.
-
High nerve density in feet: Your feet are packed with sensory nerves, so the reaction feels extra intense.
-
Skin damage: Fungal activity and scratching break down the skin barrier, fuelling even more inflammation.
-
Moisture & friction: Hot, sweaty socks and tight shoes keep the cycle going.
The result? A vicious itch–scratch–itch cycle. Scratching feels good for a second but damages the skin, spreads the fungus, and often makes the itching worse. Ouch.
How to Stop Athlete’s Foot Itch
Here’s the game plan:
1. Wash and dry thoroughly
Use warm water and mild soap daily, paying attention to the spaces between your toes. Pat dry (not rub). Moisture is fungus fuel!
2. Antifungal treatment
The only way to actually stop the itch is to kill the fungus. Over-the-counter creams can work (if you're okay with the potential ick of synthetic ingredients), or you can try a different solution like Funga Shield, our all-natural antifungal powder. It doesn’t just fight the fungus, it also keeps your feet dry, cutting off the environment fungi love, and without any artificial nasties. Win-win, right?
3. Moisture control
-
Switch out cotton socks for moisture-wicking blends or merino wool.
-
Rotate your trainers to let them fully dry.
-
Use powders (yep, like Funga Shield) in socks and shoes to absorb sweat.
4. Repair the damage
Once the infection starts clearing, your skin may still feel dry, cracked, or sore. Keep up the work until it's completely gone - remember adding moisturiser too soon will just aggravate the problem and empower the fungus for another round.
5. Don’t scratch (seriously)
Scratching spreads the infection to other areas... like your groin (hi, jock itch). If you’re desperate, apply gentle pressure, use a cold compress, or distract yourself instead.
Prevention: Keep It From Coming Back
- Wash and dry feet daily (use a hairdryer on a cool setting if needed).
- Fresh socks every day (no excuses).
-
Never go barefoot in gyms, pools, or communal showers (NHS advice).
-
Keep toenails short and clean (fungi love to hide there).
- Spray or sanitise shoes to avoid reinfection.
When to See a Doctor
See your GP if:
-
Symptoms don’t improve after two weeks of treatment.
-
The infection spreads to hands, nails, or groin.
-
Your feet develop pus, severe cracks, or oozing (signs of bacterial infection).
-
You have diabetes - in which case all foot infections need extra care.
Athlete’s foot itches because your immune system is waging war against fungi on your skin. The itch is basically your body’s “danger signal.” But scratching won’t solve it (in fact it'll make it worse) - treatment will.
Fight back with Funga Shield and keep your feet clean, dry, and protected. Your feet carry you through your workouts, your runs, your hikes, and everything else - they deserve to be itch-free, healthy, and strong.
Because nothing should stand between you and smashing your fitness goals. Not even the Itch Monster. Now, go get it!

Frequently Asked Questions
Why does athlete’s foot itch so badly?
Athlete’s foot itches because fungi invade the skin and trigger your immune system to release histamines. These chemicals irritate nerve endings, making your brain send powerful “scratch me now” signals.
How can I stop athlete’s foot itch immediately?
Quick relief comes from washing and drying feet thoroughly, using antifungal treatments like creams or powders, and soothing the skin with natural products such as Funga Shield. Cool compresses can also help calm the urge to scratch.
Is it bad to scratch athlete’s foot?
Yes! Scratching may feel good for a second, but it damages the skin, spreads the fungus to other areas (including potentially your groin), and increases the risk of bacterial infection.
Can athlete’s foot go away on its own?
Unlikely. Athlete’s foot usually persists or worsens without treatment. Antifungal products like Funga Shield are needed to eliminate the fungus and stop the itch.
How do I prevent athlete’s foot from coming back?
Keep feet clean and dry, wear moisture-wicking socks, rotate shoes, and avoid walking barefoot in communal showers or gyms. Regular use of antifungal powders like Funga Shield as a preventative can also reduce the risk of reinfection.
