Check the soles of your Nike air max shoes for areas you need to pre-scrub. If there are stains, or ground-in dirt, then use a toothbrush and gently scrub until most of it is removed. If necessary, put a little liquid dishwasher detergent on the bristles of the toothbrush.
Remove the shoelaces and lift the tongue of the shoes to expose as much of the inside as possible.
Place the shoes, bottoms up, on the bottom rack of your dishwasher. Place the shoes several inches apart. Add the dishwasher detergent to the machine. Do not put dirty dishes in with your shoes. Set your dishwasher on the normal cycle but be sure to turn off the heat dry cycle.
When the dishwasher cycle is finished, remove the shoes right away. If the shoes have any residue on them, gently brush it off with the toothbrush. If any areas are not as clean as you would like scrub the area with the toothbrush.
Lift the tongue out of the shoe and lay it over the toe of the shoe to expose as much of the inside of the shoe as possible. Place the Nike outlet shoes under a fan set at medium speed overnight.
In the morning, your Nike air max shoes should be cleaned, dry, and odor free. You just need to put the new shoelaces in and head off to the gym.
