"Since childhood we’ve been ordered to “take your shoes off before you come into the house” or “wipe your feet” on the doormat, and we’ve obeyed without question. But how dirty are our shoes really?
When you start to think about it, they are the only part of us that come into contact with all kinds of surfaces, dirt and bacteria apart from our hands. And we wash those regularly (at least most of us do). So, understandably, shouldn’t we know what exists on the bottom of our shoes? And whether they are as dirty as we’ve been told.
Food, people and their pets are the most common carriers of germs into a home. And the soles of our shoes are the most culpable culprit."
