The Reason Why You Should Never Wear Shoes Inside Your Home


Unless it is a special occasion you should not let people wearing shoes in your home. Some researches show why this is a bad idea and the reasons are brutal.

Some bacteria may be good for us, but in the case of stomach flu, you know that the other types can be dangerous. One research conducted at the University of Arizona discovered 421.000 types of bacteria in shoes.

A coliform bacterium is a bacterial indicator that shows the sanitary level in water and foods (and generally present in feces) and it was noticed in 96% of shoes.

Besides that, the research discovered Escherichia coli along with 7 other types of bacteria in 27% of the shoes. One of them was Klebsiella pneumonia that may cause urinary tract infections and another one was Serratia ficaria that may cause respiratory tract infections, stated Dr. Kelly Reynolds, professor, and microbiologist at the University of Arizona.

The researchers wanted to discover more about the bacteria transfer from the shoes to our homes. They discovered that the transfer is 90- 99%.

Dr. Charles Gerba, microbiologist and professor at the University of Arizona stated: “The frequent appearance of Escherichia coli and coliform bacteria on the shoes indicates that we are in contact with feces that come from the floor in public restrooms or from droppings.

Our research shows that once the shoes are contaminated with bacteria they can easily be transferred to our homes”. The floors in the public restrooms contain around 2.000.000 bacteria on 0.00064m2.

The research made at the University of Huston showed that 39% of the shoes contain Clostridium difficile, bacteria that is a threat to the public health and it is resistant to many antibiotics. It can cause severe health problems, including diarrhea.

Another threat to our home – toxins

One research made by the Battelle Memorial Institute showed that the toxins from our lawn can easily be transferred in our homes.

Additional to that, research made at Baylor University discovered that people who live closer to asphalt road with coal tar have a higher risk of developing cancer, and these toxins can easily be found on our shoes.

“Just think about the rain. The roads are full of chemicals and all of them are transferred on our shoes. Afterward is easy to take them in our home”, says Dr. Reynolds


The research made at the University of Arizona says that washing your shoes with detergent can lower the appearance of bacteria for 90%.

Additional to that it is recommended to clean your floors and carpets with carpet disinfectant.

For best results keep your shoes out of your home.
