Bacteria on the feet can have both positive and negative roles. The skin on our feet provides a warm and moist environment that can make it an ideal place for bacteria to grow. While some types of bacteria can cause foot odor and infections such as athlete's foot and toenail fungus, other types of bacteria can help prevent harmful bacteria from growing and keep the skin on our feet healthy. For example, certain natural bacteria on our skin help to maintain pH levels and prevent the overgrowth of harmful bacteria. Additionally, probiotic foot products have been developed to reintroduce beneficial bacteria to the feet to help prevent infections and improve foot health.
