Anyone who has worn sneakers knows that with continuous wear they hold on to foot odor. Clean smelly New Balance shoes to get rid of embarrassing foot odor. Athletic shoes are more prone to smells from perspiration due to exercise. Anyone who actually runs in running shoes is going to perspire in them. Strong foot odor is a genetic trait, but an odor in shoes may indicate the presence of fungus or bacteria. Clean smelly New Balance shoes to avoid foot and toenail infections.

Spray smelly New Balance shoes with a hose. Use a high pressure stream from the sprayer nozzle inside and out.

Mix and test a cleaning solution. Pour a 1/2 gallon of water into a bucket and add 1/4 cup of ammonia. Wet the corner of a cleaning cloth with the solution and use it to wet a small portion of any fabric on one shoe to make sure it is colorfast. Most running shoes are man-made materials that are colorfast, but some have suede trim that is vulnerable to color bleeding. Mix and test a solution with less ammonia if bleeding occurs.

Soak New Balance shoes in the ammonia solution. Remove the shoe laces and drop them into the bucket. Submerge the stinking athletic shoes completely in the bucket and let soak for 45 minutes.

Scrub shoes inside and out. Run a scrub brush or toothbrush over the outside surfaces and trim. Wet a cleaning cloth with the ammonia solution and rub it around the inside of the shoes.

Rinse and dry thoroughly. Rinse with the sprayer of the hose. Keep rinsing until the water running off the shoes is clear. Shake off all excess water and leave the New Balance shoes in a cool dry place for 24 hours.
