I love to make people feel comfortable in my home and I feel like taking off shoes helps with that because it makes a visit much more personal and homely for the guest. Shoes off is so much more comfortable, I don’t understand why anyone would want to keep their shoes on in someones home.
I live in a place where it’s abnormal to remove your shoes as guest but no one has ever complained.
The first thing I do for guests is hand them a pair of slippers. Sometimes they decline, sometimes they don't. But that is my way of saying "shoes off" even if it's customary in Poland.
