There are some simple steps in reducing foot odor. The first step, obviously, is to thoroughly wash your feet every day, including in between your toes (where bacteria can develop). You should also dry your feet and apply a powder to reduce perspiration. Another important tip is to wear cotton, wool, or moisture-wicking socks and change your socks at least once a day. If possible, do not wear the same shoes every day – this allows the insole to completely dry before you wear them again to reduce the growth of bacteria. If you continue to have foot odor, visit your podiatrist for an evaluation.
