A study done by Dr. Charles Gerba, a microbiologist and specialist, found that over 2,887 units of bacteria can be found on the inside of the average shoe. This host of bacteria is linked to many health concerns such as infections, wounds, and more (1).
Some of the bacteria that can be living inside your shoes ranges from E. coli, B. Serratia Ficaria, C. Klebsiella Pneumonia among others. These bacteria are known to be the cause of many health issues and the cause of odor. They thrive inside shoes due to the dark and warm environment. (2)
How do you combat these bacteria in your shoes?
Keeping shoes clean by gently washing them is a good method to get rid of any existing bacteria. We do not recommend fragrances or any other methods that simply masks the smell but doesn't kill the bacteria that is actually living inside the shoes.
Keeping a pair of shoe deodorizers inside your shoes when you are not wearing them is a great method to help kill bacteria and prevent them from growing. A natural shoe deodorizer that uses mineral salts helps create an environment that makes it hard for bacteria to grow. It also acts as an absorbent and preventive for bad odor.
