Let’s dive into a topic that might make you squirm a bit: the cleanliness of wearing shoes in your home. If you enjoy keeping your shoes on while you relax indoors, you might want to reconsider after hearing what the research has revealed. Honestly, I used to be just like you, but after digging into this subject, I’ve changed my perspective—and it’s a bit unsettling.
Take a moment to breathe. Maybe even step outside for a second.
Okay. Now, a fascinating compilation of studies from various universities, including a significant one from the University of Arizona, has shed light on just how filthy our shoes can be. On average, researchers discovered around 421,000 different bacteria residing on footwear. Yes, some of that is fecal matter. E. coli was found on nearly a third of the shoes examined, alongside several other bacteria that can lead to infections.
You might be wondering: “How much of that bacteria actually makes its way into my home?” Well, the same University of Arizona study showed that an astounding 90% to 99% of bacteria can transfer from shoes to clean surfaces within your home. That’s a staggering number!
Dr. Sam Taylor, a microbiologist at the University of Arizona, noted that the frequent presence of coliform and E. coli bacteria on the outside of shoes likely indicates contact with fecal materials from public restrooms or pets. His findings also pointed out that bacteria can travel quite a distance into your living space after being picked up by your shoes.
But wait, there’s more! A study from Baylor University indicated that those who live near asphalt roads treated with coal tar may be at an increased risk of cancer due to toxins tracked indoors by shoes. Similarly, research by the Battelle Memorial Institute highlighted how lawn care chemicals can easily find their way into your home via footwear.
What Can You Do About This?
Well, the studies suggest a few practical solutions: wash your shoes regularly, steam clean your carpets, and most importantly, consider removing your shoes upon entering your house.
As a parent of three, I can relate to the struggle of keeping shoes off in the house. I remember a moment when my youngest was just a toddler, happily chewing on one of my shoes. It was adorable then, but now I can’t help but cringe at the thought of what he might have ingested. While I doubt shoes will lead to serious health issues, especially during cold and flu season, every little precaution can help keep my family healthier.
Of course, I’m not a doctor, and perhaps some exposure to bacteria isn’t all bad for the immune system. Or maybe I’m just trying to justify my habit of wearing shoes indoors. Either way, the evidence is clear: our shoes are more contaminated than we ever realized.

In summary, while wearing shoes indoors may seem harmless, the scientific evidence suggests otherwise. It’s wise to consider taking them off at the door to protect your home and family from unwanted bacteria and toxins.
