Bacteria that feed on the dead skin cells of your feet cause foot odor. A good warm-weather foot-care routine tames the bacteria and reduces the embarrassing smell plaguing your summer sandals. Wash your feet daily with an antibacterial soap and dry them thoroughly, making sure you get between your toes. And rotate several pairs of shoes rather than wearing the same ones daily.

Sole Cleansing

For mild odor, spray the insoles of your sandals with a disinfectant and set them in the sun. Waterproof sports sandals with rubber, plastic or vinyl footbeds can be washed with mild soap or baking soda, warm water and a soft-bristled brush. These sandals can also be scrubbed in a solution made of 1 cup of antibacterial mouthwash and 2 cups of water or equal parts white vinegar and water. Water shoes can also be placed in a swimming pool treated with chlorine for 15 to 20 minutes. Some manufacturers suggest running sandals through the washing machine on the gentle cycle.

Chill Out

This universal trick works for sandals and insoles of all materials, including leather. Put your sandals or their removable insoles in a freezer bag. Sprinkle some baking soda into the bag and seal it. Place the bag in the freezer for two to four hours to kill the bacteria. Remove the sandals from the freezer and use a stiff brush to clean off the baking soda.
