Your shoes are part of your health routine

Athletes track sleep, nutrition, and recovery down to the gram. Almost nobody tracks what is living in their shoes. That is a gap, because the inside of a training shoe is warm, dark, and damp for hours after every session, which is exactly what bacteria and fungi need. Our deep dive on what is actually growing inside your gym shoes walks through the organisms involved and how fast they multiply.

Some of those organisms cause more than odor. Athlete's foot keeps coming back for most people because they treat their skin and ignore the shoe, which acts as a reservoir for the fungus. We also look at whether gym shoes can make you sick, and at the gym bag problem: why your bag smells even after washing.

Sport by sport

Risk depends on the sport. Court athletes who play several times a week face the highest exposure, which we cover in the pickleball foot health guide for high-frequency players and the shoe mistake millions of new pickleball players make. Indoor tennis has its own issues, covered in our indoor tennis shoe hygiene guide. Grapplers deal with skin infections that spread on the mat, so we wrote a separate hygiene guide for BJJ and MMA practitioners. And serious CrossFit athletes clean their shoes differently for performance reasons as much as hygiene.

For parents and everyone else

Kids share locker rooms, borrow gear, and rarely dry their shoes properly. Our guide to youth sports foot hygiene covers what parents should watch for. If you are wondering when a pair is simply done, read how long gym shoes actually last. And if you have ever been the person everyone can smell in the change room, the embarrassing gym moment nobody talks about is for you.
