I think this question is a bit absurd because in the civilized world taking shoes off while inside an apartment or a house should be taken for granted.

My flat is a mess, but I still fucking hate it when small grains of sand and rocks get carried inside in people's shoes.

Never.

i have smelly feet usually. They get wet and the scent occurs when the moisture from the water mixes whith that of my sweat. So, I feel very self-conscious about my smelly feet and wouldn't want the same doo to befall another person, plus my house is hardwood flooring and tends to be a tad bit chilly. I promise you peole if you come to my home, you will NEVER be forced to your shoes off. It is all up to you.

When we first moved in we did, and we took them off ourselves. We have gotten lazy about this now though; as long as you aren't tracking in large amounts of the outside elements, you are fine.

I'd like to especially after I mop. Its kind of useless. but NYC gets weird shit on yr feet...
