Physical activity creates perspiration and that often results in bacteria and odor. This is especially an issue with bowling shoes, which are rented at the alleys and used by many different people. A disinfectant spray must be antibacterial. Whether or not you bowl, properly disinfecting shoes can also help eliminate odors during other modes of physical activity, such as running or playing basketball.
Place the shoes on top of a counter in a well ventilated room.
Loosen the laces on the shoes, particularly the laces nearest to the tongue of the shoe.
Aim the front of the spray away from your face. Holding the tongue of the shoe up, spray the inside of the shoe up to the opening of the shoe.
Repeat step 3 for the other shoe.
Keep the spray away from the eyes and mouth.
