“Don't put your shoes in the washing machine. The soaking doesn't help the sole or arch support construction in the slightest,” says former shoe store manager Ben Nettleton, now an affiliate director at the Global Healing Center in Houston. To keep the outside of your sneakers squeaky clean, Nettleton recommends investing in athletic shoe foaming cleanser and scrubbing the surface with an old toothbrush. For the insides, try using Gold Bond medicated powder, baking soda, or other similar deodorizing (but dry) products.
