It can be embarrassing, but foot odor is something we all get on occasion. The main cause of the offense is sweat. Or more precisely, the by-product of bacteria feeding off the sweat that is released from your feet and soaks into your shoes. In some cases, persistent foot odor can be a symptom of a skin infection or of an open wound, says Louisville podiatrist Dr. Fred Preuss. Diabetes sufferers who experience a loss of sensation in the feet are especially vulnerable to infections and should see their doctor if they notice any odor.
