I've seen both in the UK. Personally, I'm a shoes off guy. Means less cleaning needed.

For me, in Italy it's both, in 90% of the cases the situation is like:

You get in, remove the shoes and go barefoot/with slippers, if it's like a party, festivity etc etc, usually no one cares to get off the shoes

UK too, shoes off too, have never lived anywhere where shoes on indoors was a common thing

The only reason I can think is that underfloor heating is relatively rare here and if you've got hard floors it'll be cold to walk on, but then slippers exist so idk really

It might be in including having slippers or "indoor shoes". Nigeria is there as a shoes on, but from my understanding, its only slippers/flip flops specificly for indoors, that are normal.

Edit: Talked to my Nigerian friend, shoes off is expected, and slippers are just a personal preference. The map is just wrong.

I reckon it depends on how warm someone's home is and how good their circulation is. If I don't have shoes on indoors, then for half the year it feels like my feet have been stabbed because they get so cold (slippers are not enough), but I don't wear the same shoes indoors as outdoors. I suspect that if we set the heating higher and the house wasn't constructed in a way that makes the floor always much colder than a few inches above the floor, this wouldn't be a problem.

Grew up in the UK, in a "shoes on" household. We just gave them a good scrape on the doormat when coming inside.

Since then, I've lived in a few different countries and am 100% converted to the shoes off way of being. I agree it's much better.

The same in NZ. Is this that you never ever wear shoes on inside?

Is it acceptable to walk into your own house and walk around with shoes on? Sure.

Do most people do that most of the time? In my experience, people will be shoes off in their own home most of the time, but it's not some big taboo to keep them on if you're popping in to grab something.

US here. Depends really. If I'm working around the house I like my shoes on but when it's time to shutdown. They off, maybe some flip flops if I head out to the pool

Same for the U.S. Sometimes downstairs or in common areas for guests.

Does anyone here do shoes on indoors?

In/out doors doesn't really make a difference. If I need shoes outside, I'm probably wearing them inside. And vice versa.

It would be different if I had carpet. Carpet is impossible to thoroughly clean in situ. I would never want outside shoes on non-rental carpet. But I've got 100+ year old hardwood floors that have seen way worse than I'm tracking in.

So when I visited my friend that moved there, the rule was if you aren't muddy shoes on in the first floor is fine but no shoes on the second floor.

They also have guests slippers for the first floor. I think this kinda makes sense since they like having parties then they don't allow anyone upstairs.

My parents keep their shoes on, I take mine off.

Same with France, many if not most no longer wear shoes inside of their homes.
