#3. Put baking soda in your shoes: Shake baking soda into your shoes so that there’s a thin layer of it, and let it sit overnight. (Don’t use this method with leather shoes; it’ll dry them out and potentially ruin the leather.) If you don’t have any baking soda — what’s the matter with you? — use salt instead; it too will soak up moisture and leg-sweep odor.
#4. Buy an antibacterial spray for your shoes: Products like Sanifeet Shoe Disinfectant ($20 @ Amazon.com) seeks and destroys odor-causing bacteria. Sanifeet uses Podiatine, an antimicrobial ingredient that kills 99.9 percent of the stuff that makes you want to cry when you take a whiff of your sneaker.
