Don’t they clean the shoes for bacteria. I recall a program segment where the owner of a bowling alley said they hot steam dry the shoes. Who knows. I rather buy my own bowling shoes than renting them.
I remember seeing them spraying something in the shoes, but not sure if all places do it, and not sure how effective it would be.
I don’t know either….I hadn’t thought about it until it was brought up. Feet do sweat….
