Shoes can carry a significant amount of bacteria from the streets into homes, posing potential health risks for children. In some households, removing shoes upon entering is uncommon, though this practice is widely observed in many cultures, especially in Asia. While some may find it inconvenient or feel awkward doing so in others’ homes, this simple habit offers considerable health benefits.

Héctor Alonso, a podiatrist and surgeon who shares insights on social media about footwear, foot health, and common misconceptions, recently emphasized the importance of this practice on Instagram (@hectoralonso.podologo). In a reel, he warned about the hazards of not taking off shoes indoors, citing a scientific study conducted in New York. The research revealed that streets, even those appearing clean, contain over 30,000 fecal bacteria, many of which end up in home carpets. Within just 15 days, more than 420,000 bacteria can accumulate on floors.

“Viruses thrive better on shoes than on toilets,” Alonso explained, highlighting the particular risk this poses to homes with young children or babies. Children frequently play on the floor and touch their mouths, increasing their exposure to these harmful microorganisms.

The post sparked significant engagement, with many people sharing their perspectives. While some dismissed the idea as excessive, others described it as a fundamental hygiene practice they have followed for years: “Taking off shoes is essential. As soon as I get home, I switch to slippers!” one user commented.

The tradition of removing shoes at home is deeply ingrained in Japanese and Chinese cultures. Historically, unpaved streets and wooden homes prone to dirt accumulation led to the development of this custom. These homes often feature a genkan, a dedicated area for leaving shoes, with flooring distinct from the rest of the house.

Given the high bacterial load that shoes can introduce, especially in environments with small children, adopting this simple habit can significantly improve household hygiene and health.
