Most people wear socks in the winter … I am not one of them. On the rare occasion I just can’t warm up my bare feet, I wear slippers until they overheat. Between menopausal hot flashes and thyroid medication, my feet are mostly comfortable.
My kids are bare feet people like me; Mike wears socks.
If you go to someone’s house, you kick off your shoes at the front door, just like you would at home. Canada has 5’ish months of snow, and numerous rainy months, so one’s shoes are often not dry.
I did two open houses last weekend. Even though the weather was dry, people without hesitation either left their footwear on the porch, or put (builder-supplied) booties over their shoes.
