Coming from a shoes-on culture I can give a couple points.

First, in the rare cases you describe (when was the last time you stepped on feces?) one would indeed leave their shoes outside. But in the day-to-day your shoes have some dust on them and that's it - you won't even notice it's there when compared to the dust that already accumulates daily. If you live in a climate where this assumption doesn't hold (snowy areas come to mind) then the equation changes.

Second, the floor is usually stone and therefore designed for being walked on with shoes. I would feel awkward walking on some polished wood, but if the difference between inside and outside is "this one is less coarse but just as hard" then I wouldn't see a good reason for taking my shoes off. I would probably avoid the rug, but that's me.

As for comfort, keeping your shoes on also means one less thing to do when going in and out. Do not underestimate the path with less friction.

I have seen in Switzerland that people leave their shoes at the entrance and switch to house shoes. Or they use a shoe cover when they enter house with shoes. Probably because houses are mostly wooden floored.

So shoes on is not universal in the West.

  • Most of the west outside of the US takes shoes off or swaps 'em for indoor shoes.

    • Between "Most of the west" and "Asian countries" it seems like it's the vast majority of industrialized countries that take off or swap their shoes inside. There's just an odd blip of over-represented online people who don't.

> when was the last time you stepped on feces?

Try this , when was the last time you stepped somewhere that had previously been stepped on by someone who had walked on a spot which had been stepped on by someone who may have stepped on a spot trod on by ... go far enough back and it's all had feces on it to some small degree.

An easy way to keep this concept clear and understand the reasoning behind a 'leave the outside shoes out of the house' is something learned as a child.

Just like there is a Law of Conservation of Mass, and a Law of Conservation of Energy, and these two are the same law as defined by Einstein, there is also a Law of Conservation of Filth. The law may be stated as: "A spoonful of wine in a barrel of pigshit is a barrel of pigshit. A spoonful of pigshit in a barrel of wine is... a barrel of pigshit."

Taking off the outdoor shoes to come indoors changes the "is there trace amount of feces on my dining room tatami floor?" risk from "I cannot be reasonable sure," to "I can be reasonably sure that there is none." If guests find that too much friction to understand and accommodate, one might argue for a different set of guests who are less accepting of an allowable amount of pigshit in their wine.

  • I'm going to disagree with your law of "conservation of filth" on the grounds that it's pushing things too far. Whatever amount of feces comes into your system via walking downtown on a regular day and then bringing the shoes inside pales in comparison to the amount of fecal matter that enters via your toothbrush if you keep it in the bathroom. At some point a small amount of dirt is just fine, as evidenced by my immune system not even visibly reacting whenever I pick up and eat something that fell on the floor (as long as I follow the five-seconds rule). And people do go out to restaurants or, even worse, picnics, where all that separates their food from a much filthier surface is a piece of cloth.

    I'm not going to say that every type of floor is to be walked on, with rugs and tatami mats being perfect counter-examples. But if a five-star restaurant doesn't ask me to take my shoes off (not evening Japan, AFAIK) then keeping them on is, from a sanitary point of view, probably okay.

    • The toothbrush analogy is weird, and untrue in most cases. And regardless, just one time stepping in crap, would make up for a lifetime of a few molecules hitting a brush at random intervals.

      And of course, toothpaste is a cleaner, so it's not relevant.

      But I find this all amusing, because wherever you take your shoes off? That's where all this supposed crap sits from all these shoes left outside. Which means you are walking in your socks in that area, after shoe removal, and entering the house.

      So unless you levitate out of that area, your feet are still covered in this supposed crap.

      The shoe rule in Japan stems from damaging floors. And checking your feet, shoes or not, is just prudent. But your feet or clean looking shoes?

      Equally dirty.
