#39: No Shoes Indoors

We’ve all heard the age-old rule about removing your shoes when entering someone’s home, right? Well, there’s solid science behind that nugget of etiquette. According to this Reddit user, wearing your outdoor shoes indoors can track in all sorts of unpleasant stuff – think dirt, bacteria, and who knows what else – that can seriously impact your indoor air quality.

Not to mention, it’s just plain impolite to traipse around someone’s living space with muddy, dirty shoes on. This rule should also apply to your own home. After all, who wants to wear outdoor shoes indoors anyway? It’s far from comfortable! That’s precisely what house slippers are designed for.
