I take shoes off as soon as I can, wherever I can. The moment I step inside my front door I release my feet, and I do the same at friends' houses. It has never occurred to me to do otherwise, and I'd never met anyone who has as much as mentioned it. I really couldn't cope with anything on my feet when at home.
My kids used to laugh at me for saying I couldn't think with shoes on, but I can't.
I spent most of my childhood barefoot, and could run across the pebbly Brighton beach with ease. (I can still walk along the pebbles barefoot too
)
I think nothing of taking my shoes off to walk home if I've been out in heels, regardless of the weather. It actually feels lovely in the rain 
Oh yes - I do believe I have some IKEA furniture too
