Persistent foot odor is an uncomfortable and embarrassing condition that affects people of all ages. It occurs when feet sweat while wearing shoes, creating a perfect environment for bacteria to thrive. The bacteria that grow in the shoes and on the skin are responsible for the unpleasant odor.
The warm, dark environment inside shoes provides an ideal breeding ground for both bacteria and fungi, which contribute to foot odor. The good news is that this condition can often be controlled with simple preventive measures, including proper foot hygiene.
Request an AppointmentCauses of Foot Odor
At its core, foot odor is caused by sweating. The feet have more sweat glands than any other part of the body, approximately 3,000 glands per square inch. When your feet sweat in shoes, there’s nowhere for the moisture to evaporate, allowing the sweat to mix with bacteria on the skin, resulting in odor.
People who sweat excessively are more prone to developing foot odor. Factors that can increase sweat production include:
- Certain prescription medications
- Hyperhidrosis (excessive sweating)
- Hormonal changes
- Stress
Foot Odor Treatment
The most effective way to address foot odor is through prevention. Consider the following steps to keep your feet fresh:
- Alternate shoes to give them time to dry out between uses.
- Always wear socks with shoes, especially closed-toe footwear.
- Change socks frequently throughout the day if they become damp.
- Dust your feet with non-medicated foot powder to absorb moisture.
- Keep an eye out for any signs of fungal infections.
- Wash your feet daily with soap and warm water, making sure to dry them thoroughly, especially between the toes.
- Choose shoes that allow your feet to breathe.
- Wear thick, absorbent socks that can help manage moisture.
If these measures don’t eliminate foot odor, your podiatrist may recommend stronger treatments. Persistent odor may also be a sign of an underlying infection, so it’s important to consult a doctor if the problem doesn’t improve with home care.
