A smelly shoe or sneaker is no match for the power of baking soda. Liberally sprinkle soda in the offending loafer or lace-up and let it sit overnight. Dump out the powder in the morning. (Be careful when using baking soda with leather shoes, however; repeated applications can dry them out.) You can also make your own reusable “odor eaters” shoe deodorizer by filling the toes of old socks with 2 tablespoons baking soda and tying them up in a knot. Stuff the socks into each shoe at night before retiring. Remove the socks in the morning and breathe easier. Try these other brilliant uses for baking soda.
