Foot odor and stinky shoes can be embarrassing and frustrating when nothing you do to help eliminate the problem seems to work. While smelly feet are usually harmless from a health standpoint, the odor can be a symptom of an underlying medical problem that may require treatment.
Causes
The most common cause of stinky feet and shoes is excessive perspiration. Your body's sweat glands help regulate temperature, which can cause your feet to sweat profusely, especially if you wear thick socks or shoes with little or no ventilation. Foot fungus can also lead to odor and other foot problems. Athlete's foot is a common fungal infection that can lead to odor, itching and cracked or sensitive skin on the soles of the feet and between the toes.
Considerations
Some people are more susceptible to foot odor and fungal infections than others. Athlete's foot is more common in adolescent males than females, according to the Massachusetts General Hospital for Children. Teens who are overweight or have diabetes are more likely to develop athlete's foot and other fungal infections that can lead to foot odor as well. People who sweat excessively in other parts of their bodies may also be more apt to develop foot odor from sweat.
Home Treatment
Keeping your feet clean and free of bacteria is important in controlling foot odor. Wash and dry your feet thoroughly at least once a day and following physical activity to help keep your feet odor-free. Sprays and powders meant to absorb excess moisture and rid your shoes of unpleasant odors can also help. Some powders contain antiperspirants that you can use directly on your feet to keep foot sweat to a minimum. Placing your shoes in a well-ventilated area can help them dry out more quickly than placing them in a closet.
Medical Treatment
In most cases, medical treatment for stinky feet is not necessary. Doctors may prescribe aluminum chloride drugs for people with severe perspiration problems. Prescription antiperspirants are also available, though they are rarely used on feet because of their tendency to irritate the skin. Ask your doctor about prescription medications to clear up fungal infections if over-the-counter topical creams do not clear up athlete's foot or other infections.
Prevention
You can prevent stinky feet and shoes in many cases by simply practicing good hygiene and making good choices regarding footwear. Shoes that fit too tightly or improperly can lead to excess sweating and odor. Shoes made of natural materials are a better choice for controlling perspiration than footwear made of synthetic materials, such as plastic. If you engage in regular physical activity, change your socks regularly and purchase cotton athletic socks that absorb or wick away moisture.
