Stinky feet is not something to turn your nose up at. It can be a medical condition called bromhydrosis. Sweat glands secrete fluid. Bacteria then works on the secretions and causes an unpleasant odor. This can be embarrassing. Evaluation by your doctor can determine if this is truly a medical condition and what treatment to consider. Medications to reduce perspiration of the feet, topical antibiotics, topical antifungals, foot soaks and even botox may be considered by your physician.
Other things to consider if your feet smell: Wear socks with shoes. Materials and dyes in shoes can react with our sweat to produce an unpleasant odor. Wash your feet daily with soap and water. Change wet or sweaty socks promptly. Avoid nylon or polyester type socks, as these fibers do not allow for good ventilation of the feet. If this does not help, consult with a podiatrist for evaluation.
