Rather than spend money on shoe deodorizers, you probably have one right in your kitchen! All you need to rid those smelly shoes and sneakers of odor are 2 tablespoons of baking soda poured into the center of a coffee filter. Secure with a rubber band. Place one of these in each shoe and overnight the baking soda will have absorbed the odor through the porous coffee filter. Now you’ll have no worries when you remove your shoes!!!
