Use Rocket Pure Natural Shoe Deodorizer for your shoes. You should repeat this process with the shoes every now and then if they get stinky again. I usually spray about 3-4 shots into each shoe. I then let my shoes dry overnight, although they probably don't need that long. If you need more info on shoes deodorizers, check this
