Shoes Inside? A New Look at What Our Floors Are Really Carrying
A recent wave of research is changing the way people think about the simple habit of leaving shoes at the door. Studies have shown that everyday footwear can harbor a surprising mix of microbes gathered from streets, parks, and public spaces, and these microbes can be tracked indoors, landing on floors, carpets, and kitchen counters. The question for Thai households is not only about cleanliness, but about how our homes, families, and communities might be affected when guests or residents bring footwear inside. The message is straightforward but nuanced: removing shoes at the threshold may be a practical step to reduce the microbial journey from outside to inside, especially in spaces where children crawl, elders sit, or meals are prepared.
