Experiencing smelly feet, known medically as bromodosis, is quite common. This condition can be uncomfortable and potentially embarrassing. I once treated a patient whose spouse insisted he remove his shoes and socks at the entrance and use a bacterial wipe before entering their home. He sought my assistance to resolve the issue.
It can be challenging to notice your own foot odor, but others certainly will. A helpful tip is to take a whiff of your feet and then imagine the smell amplified by ten. That’s how strong the odor can be for those around you.
Feet become odoriferous because bacteria thrive in dark and moist environments. Remarkably, an average foot is home to approximately 3.5 million bacteria colonies per square centimeter, along with about 24 fungal colonies.
As these microorganisms proliferate, they decompose dead skin and oils on your feet, releasing a range of potent odors. No demographic is immune; everyone experiences foot odor at some point.
Additionally, bacteria can accumulate on your shoes. A study by the University of Arizona found that an average of 421,000 bacteria units, including E. coli, were present on the soles of shoes from ten participants, while 2,887 units were detected inside the shoes.
Unpleasant foot odor typically results from inadequate hygiene, but it may also signal underlying issues such as:
Hyperhidrosis: This genetic condition affects about 6% of the population and leads to excessive sweating. Feet are already equipped with 250,000 sweat glands per pair, producing up to half a pint (1.2 cups) of sweat daily. Hyperhidrosis exacerbates this, creating an even more conducive environment for bacteria, which can lead to a stronger, vinegar-like smell.
Athlete’s Foot: Known as tinea pedis, athlete's foot is a fungal infection that leads to a red, itchy rash on the feet. It can spread to others and to different areas of your body, so it's important to avoid sharing shoes or socks. This condition often has a smell reminiscent of stinky cheese and can be treated with over-the-counter antifungal medications like Lotrimin AF or Lamisil AT, with improvements typically seen in two to four weeks.
Bacterial Infection: Pitted keratolysis, caused by an overgrowth of the bacteria Kytococcus sedentarius, affects 10% to 15% of people. This condition is marked by small pits on the soles and a mushy appearance of the skin, producing an odor similar to rotten eggs due to volatile sulfur compounds.
How to Prevent Foot Odor
Maintaining proper foot hygiene significantly impacts how your feet smell. Here are some essential tips:
Socks: Always wear socks! Going without them creates a damp environment in your shoes, promoting bacterial and fungal growth. Choose clean, cotton socks each day, as this material is moisture-absorbing. Steer clear of synthetic fabrics like polyester and nylon, which trap moisture.
Medicated Socks: Consider investing in socks with antimicrobial properties, such as those containing silver or copper ions. However, be mindful that their effectiveness may diminish over time, especially after multiple washes.
Footwear Choices: Avoid tight shoes. Opt for breathable materials like canvas or mesh, especially in warmer weather. If your shoes are wet, allow them to dry completely before wearing them again. Whenever possible, remove your shoes and socks to let your feet air out.
Daily Washing: Clean your feet daily with antibacterial soap. Keep toenails trimmed short to prevent bacteria buildup underneath, and use a foot file to remove any hard skin.
Talcum Powder: Using foot powder can help absorb excess moisture. Various options are available, some of which contain beneficial ingredients like bentonite or potassium aluminum.
Antiperspirants: For those struggling with wet, smelly feet, look for antiperspirants containing aluminum chloride, which blocks sweat production. Drysol, with its high concentration of this ingredient (20%), is a strong choice.
Note that many over-the-counter foot antiperspirants contain alcohol, which can lead to excessively dry skin and increase the risk of cracks that allow bacteria to enter.
Foot Botox: In severe cases, especially with hyperhidrosis, Botulinum toxin can be used to reduce sweating on the feet. Iontophoresis, a procedure that uses a mild electrical current, can also temporarily disable sweat glands and is performed in a medical setting.
After treating my patient with pitted keratolysis, I received a heartfelt thank-you note. Following a course of antibiotics, discarding a pair of shoes, and sanitizing the rest, he was allowed quicker access to his home. He wished he had sought help sooner.
