Freshen up your smelly shows by following these few easy steps to get your shoes smelling like new again. Odor-causing bacteria thrive in dark, damp spaces, which makes your sweaty tennies an ideal habitat. You’ll need to wipe out the smelly bacterial population to achieve truly odor-free shoes.
Examine the shoes. Are the insoles damp and causing the odor? Remove them and dry them. Or replace them with insoles formulated to kill bacterial growth, available at drugstores.
If odor remains after the freezing, pour baking soda into the shoes and leave it in overnight to absorb the odors. Or use products designed to remove shoe odor, which are available at supermarkets and drugstores.
