Smelly Feet: A Minor Issue That Can Turn Serious

Ever taken off your shoes only to be hit by an unpleasant odor? You’ve changed your socks regularly, your shoes are clean, and yet, the smell persists.

It’s embarrassing and can seriously hurt your confidence, especially when you need to remove your shoes in public. But don’t worry, you’re not alone—and the good news is, it’s treatable.

What Causes Smelly Feet?

This condition is medically known as bromodosis. The leading causes include:

1. Excessive sweating
   Did you know the soles of your feet have about 250,000 sweat glands—more than any other part of the body? It’s no wonder feet get damp and sweaty, especially in hot weather, during exercise, or after prolonged periods of standing.
2. Bacteria
   Sweat itself doesn’t smell. But when it mixes with bacteria on your skin, it produces a foul odor. One major culprit is a bacterium called Kytococcus sedentarius, which produces sulfur compounds that have a rotten egg-like odor.
3. Fungal infections
   Damp feet are a perfect breeding ground for fungi, such as the ones that cause athlete’s foot (tinea pedis). Besides itching and cracked skin, this infection can also cause a strong foot odor.
4. Damp shoes & lack of ventilation
   Wearing the same shoes every day without letting them fully dry can trap moisture inside, making it easier for bacteria and fungi to grow.
5. Poor foot hygiene
   Not washing your feet regularly, wearing the same socks for too long, or allowing toenails to grow too long can provide bacteria with a place to thrive.
6. Certain medical conditions
   Some people are more prone to foot odor, especially those with:
   • Hyperhidrosis (a condition that causes excessive sweating)
   • Diabetes increases the risk of fungal and bacterial infections

Foot odor can also get worse due to seemingly harmless factors, such as:

• Hot or humid weather
• Intense physical activity (like sports)
• Standing for long periods
• Being overweight (more pressure = more sweat)

How Do You Deal with It?

Here are a few tips you can try:

• Soak your feet in warm water mixed with salt or apple cider vinegar for 15–20 minutes. Salt helps absorb moisture, while vinegar has antibacterial properties.
  Note: Avoid soaking if you have open wounds.
• Keep your feet dry. After showering, dry them thoroughly, including between your toes. Use foot powder or antiperspirant if your feet tend to sweat a lot.
• Wash your feet daily with antibacterial soap. Ensure that you clean all areas, including between the toes and under the nails. Dry them thoroughly afterward.
• Rotate your shoes and let them air out in the sun. Don’t wear the same pair two days in a row. Let them dry completely before using them again.
• Spray disinfectant inside your shoes and allow them to dry naturally. This helps kill odor-causing bacteria and fungi.
• Take care of your footwear. Wash the insoles occasionally and avoid wearing the same shoes every day. Give them time to dry out completely before wearing them again.

But What If an Infection Has Already Started?

If you notice peeling skin, itching, pain, or a strong odor, you might already have a fungal infection or a minor wound that’s been neglected.

People with diabetes should be especially cautious. Even a small wound or damaged skin can turn into a chronic wound if not treated properly.

Foot odor may be embarrassing, but letting it worsen into an infection is even worse.

Start taking care of your feet today, because healthy feet are a reflection of your overall hygiene.
