I don’t know about you but I notice how much shoes smell when the weather starts to get warmer outside. Especially my husbands shoes…they really stink. We have gotten those foot odor balls to leave in and other things to put int he shoes but they really do not work and the shoes really stink up the entire breezeway where we keep all of your shoes. And on a hot and humid day it is really gross. You can always try putting a fabric softener sheet in the shoe overnight. This has worked good before. But if the shoe is still stinking then try putting it in a plastic bag and freeze the shoes for a day or two. This should kill the odor completely.
