Foot fetish: Simple guide to winning the battle against foot odour

Our feet deserve the same love and care we lavish on the rest of our body. Yet they often come last in our self-care routine, and we pay the price in stench. After a long day, slipping off shoes and socks can unleash that greasy, sweaty odour.

Recent data shows around 16 per cent of adults in the US report foot odour issues, while 12 per cent of British adults admit to the same problem.

Medically known as bromodosis, foot odour occurs when bacteria feast on sweat and dead skin cells, producing pungent byproducts. Feet are a breeding ground loaded with sweat glands and often tucked away in warm, moist shoes and socks.

Conditions like fungal infections such as athlete's foot can worsen the smell, turning a simple stink into a full blown hygiene hazard.

At the heart of the odour is isovaleric acid, a nasty-smelling compound produced when Staphylococcus epidermidis breaks down leucine in sweat. Research in the Canadian Journal of Microbiology also found that Bacillus subtilis contributes to strong foot odour.

According to the Institute for Preventive Foot Health, consistent hygiene habits can significantly reduce foot odour. Cleaning between the toes and thoroughly drying feet is also very important.

If odour persists despite good hygiene, consult a podiatrist or a general practitioner. Bacterial or fungal infections, underlying conditions like diabetes or kidney disease, and even some medications can cause or intensify odour.

Foot odour doesn't have to be a life sentence. With a bit of attention and care, you can tackle the stink and let your feet breathe easy again.

Here's a simple guide to reset your feet:

1. Breathable footwear:
   Shoes made of non-breathable materials trap moisture and encourage bacterial growth. Opt for leather or canvas instead. Avoid plastic shoes. Rotate your footwear to allow time for each pair to dry, and regularly disinfect the insides.
2. Daily hygiene routine:
   Wash your feet every day using antibacterial soap, focusing between the toes. A quick rinse won't cut it. If odour is persistent, soak your feet in warm water with Epsom salt for 10 to 20 minutes. Keep toenails clean and trimmed to avoid trapping dirt and bacteria.
3. Keep feet dry:
   Always dry your feet thoroughly after bathing or swimming. Odour thrives in moisture, so this is one of the most important steps.
4. Exfoliate weekly:
   Dead skin is a feast for bacteria. Use a scrub or pumice stone once a week to remove it and stop bacteria in their tracks.
5. Smart socks:
   Wear socks made of moisture-wicking materials like cotton or wool. Change them daily or more often if your feet sweat heavily.
