After three months in Prague, I have got used to taking my shoes off but I have to say that it would be thought bizarre in England. Of course, we wipe our feet on a door mat before entering someone's house but no-one would ever take their shoes off in someone else's home. Remember, most houses still have fitted carpets - in sensible, practical colours which don't show the dirt. And anyway, we have vacuum cleaners. Most people in the UK would feel embarassed at walking round without their shoes on and as for wearing slippers that someone else has worn, they certainly wouldn't like that at all! I've got visitors from the UK here in Prague next week. My view is that a host should make their guests feel comfortable and if that means having shoes in the house because they would feel awkward,, then I certainly don't mind at all.
