How can I prevent shoes or feet from smelling bad?

Wash feet daily with soap and water, drying thoroughly between the toes where bacteria thrive. Apply foot powder or antiperspirant to control sweat, and never wear the same pair of shoes two days in a row -- give each pair at least 24 hours to air out.

Place cedar shoe trees inside your shoes immediately after taking them off and leave them in until the next wear. The cedar absorbs moisture from sweat while releasing a natural fresh scent that neutralizes odors.

Put 2-3 unused dry black tea bags inside each shoe and leave them overnight. Remove the tea bags before wearing. This is a simple, no-cost way to reduce shoe odor using something most households already have.
