Our sneakers get a workout just like we do, however, after time, they smell less than fresh. To deodorize and eliminate odor in yours pour 2 tablespoons of salt into a paper coffee filter. Tie this closed with a twist tie or rubber band. Make 2 of these sachets and place one in each shoe. Let these sit overnight. The granules of salt will have soaked up the odor causing moisture and the smell will be banished! Repeat as necessary.
