If your sweaty, smelly feet are causing problems try this to nix the odor: submerge 5 tea bags in a cup of hot water. Steep for 10 minutes. Pour this into a basin of tepid water and soak your feet for half an hour (you can do this while you watch tv or read). Let your feet air-dry. The tannic acid in the tea will have killed the odor-causing bacteria and will also dry out the pores in the skin to cut back on excessive perspiration.
