I wasn’t sure where to ask this since it’s not really a factual question. If you’re having people over, is it impolite to not wear shoes? I walk around shoeless all the time, and would everywhere if I could.
No it’s not
This might vary by region, but where I am from (Canada) shoes are not worn in the house. Socks or bare feet are fine. It wouldn’t occur to me to think of it as rude, or to think of it at all. Actually, if you did wear your shoes in the house I would probably assume you had moved from somewhere in the southern US.
No one wears shoes in my house. They’re left on the front stoop or put in the cubbies just inside. Wearing shoes is impolite–it means you’re tracking outside grime onto my floors and rugs.
The residents of a house set the rules for things like shoes within their own house.
Depends.
Is it a formal sit-down dinner in evening dress? Probably wear shoes, I’d say.
Or just people over for drinks and snacks? Naah, I don’t think it’s necessary.
Netflix and chill? Wearing shoes is downright rude (unless they’re into that!)
I think it’s perfectly fine.
It’s just a question of formality. If you’re having guests over who are business associates or some other professional relations that you don’t really know well, a certain degree of decorum is called for. If it’s friends and family, bare feet or stocking feet are just fine.
Barefoot..always.
We’re not having any important people visiting, so there’s that.
I say; if you’re foot squeamish best not come here.
It’s entirely dependent on culture, expectations, and norms, and they’re all interrelated. In our house, we generally don’t wear shoes. In fact, I generally don’t wear shoes unless I have to, no matter where I am. Barefoot or flaps for me probably 90% of the time. We have no expectations of guests to shed their footwear at our house, but most of them do, probably because we keep about four pairs of footwear near the front door (one set of flaps and one set of Crocs/equivalent for each of us), and they assume it’s a ‘house rule’. We don’t really care one way or the other, but we’re VERY casual when we entertain, no cocktail parties for us. If the first thing you do when you visit us is kick off your kicks, it signals to me that you’re comfortable visiting us, and that’s a good thing. FTR, my in-laws never take their shoes off at our place. Draw your own conclusions.
I don’t have a problem with it.
Tee hee. 
No issue here. I rarely wear shoes in somebody’s house unless it’s a shoe-wearing house. In my neighborhood, it was quite customary to take off shoes unless there’s some sort of formal event going on. This was pretty typical in first-generation type households, which is what I typically grew up in.
Barefoot I haven’t seen much – everyone was always enscocked, so far as I can envision, but I wouldn’t have an issue if the host of a house I was visiting was barefoot. After all, their house, their rules. Plus why would I even take it as “rude”?
We’re a “shoes at door” house, unless it’s a very formal event, when a lot of people consider shoes part of their suit or outfit. We just vacuum a lot after.
We do have some yoga socks washed in a box for people to borrow if they don’t have socks on and don’t want to go barefoot, or are worried about slipping in regular sox, and also a few “hospital socks” in sleeves for people who for some reason don’t want the washed yoga socks, want something warmer, or worry they might be allergic to our soap (not that I ask why– they are just there for the take, but not as in abundance, so I hope people without a reason not to will go for the washable ones, since they’re cheaper for us.
We have a place for the yoga socks to be returned, but if people don’t, we don’t say anything. The others are yours to keep, as they don’t stand up to many washings.
I am aware that people worry about fungi surviving the wash cycle. We wash footwear with a small amount of bleach in hot water (with the towels), and when we have had a lot of people over, with a lot of yoga socks to wash, they soak a bit (which happens about once a year, after the Purim party).
We are careful about what we are offering people.
We have a nice place for people to leave their shoes, as well.
In sum, very few of the kind of events were people wouldn’t want not to wear their shoes. We ask very nicely that people remove them when we do ask. Very, very few people say no, but when they do, it’s OK. We are trying to keep down the tracking in of outside crud– an occasional person with a texture or balance issue with bare feet doesn’t matter that much.
Now, for hosting? I wear yoga socks that match my outfit.
But just for full disclosure, I hate the feel of shoes on my feet.
I agree with what @MrDibble said. It depends on the event. Hosting a formal dinner party, I would wear shoes. I wouldn’t go so far as to say it’s rude to go barefoot, but it would seem a little weird. Hosting a pool party, on the other hand, it would be weird to wear shoes.
When I was growing up the idea of taking off your shoes when you entered anyone’s house was considered odd. It wasn’t until I was in my late twenties that a friend started asking everyone to take off their shoes when they entered his house. We all complied, of course, but he was the only one of us who had that rule.
I very seldom have company, and have never asked anyone to take off their shoes. I don’t wear shoes at home, just socks; a friend who visits a lot always takes off her shoes, but it’s for comfort rather than any preference on my part.
That.
What sort of event is the OP thinking of?
Tap dance party?
I can’t balance well and walk without shoes so I always bring a clean pair of crocs if I am going to a house where people don’t want you to wear shoes. I have no problem whether people are wearing shoes or going without. Whatever is comfortable.
If I come in from being out I’ll have shoes on and sometimes I don’t end up taking them off for a while and sometimes I take them off right away. Guests can do whatever the hell they want regardless of what’s going on but I’d never have a formal event or anything approaching that.
