What causes smelly feet?

Perspiration leads to the cause of foot odor. With more than 200,000 sweat glands each, your feet are one of the parts of the body that perspire most. Perspiration is basically just salt and water, so it doesn’t have a distintive smell. The smell is actually caused by bacteria on our skin that feeds on the sweat and excrete waste, which has a strong odor. Wearing the same pair of shoes every day means that sweat builds up inside the shoes. This keeps the shoes moist, contributing to the production of excessive perspiration, bacterial growth and often, an unplesant smell. If your footwear is left unused for a few days, the smell usually goes away. But once you put the footwear again, the warmth returns and so does the bad smell.
