So you just finished your kick-ass workout and you get home to take a shower. You slip off your shoes and you almost pass out from the absolutely disgusting smell. Feet are smelly. There is no way around that. But there is an easy fix for smelly sneakers and it's super cheap!
It's a cheap household item and it works wonders on smelly places in your house (including refrigerators). After you get back from the gym, spoon two or three tablespoons of baking soda into your smelly sneakers. Shake the sneakers so that the baking soda is evenly distributed throughout the shoe. Not only will the baking soda eliminate that horrible odor, it will also help the absorb sweat, which prevents your sneakers from smelling bad.
