Foot Odor

Causes of Foot Odor

The primary cause of foot odor is perspiration.  The two feet together have more than 250,000 sweat glands, and they release perspiration even during periods of non-vigorous activities.

That said, odor is not caused by perspiration alone; it results from the acid byproducts of bacteria, as well as fungal growth (usually athlete’s foot fungus, tinea pedis), which are found in sweaty feet. On occasion, chemical reactions between perspiration and footwear can also cause odor.

Foot infections also cause unpleasant odors.  It is important to check feet daily for signs of wounds, lesions or sores that might have become infected.  This is especially important for people with diabetes or other conditions that limit blood flow to the extremities.
