Winter is extremely different. Please read my previous comment "Of course, all bets are off if said shoes are covered in snow or mud." I come from a tropical country... there is no snow there. If i am covered in mud or snow I would leave them right at the door.To everyone that doesn't take off their shoes, what do you do in the winter? Your shoes/boots are dirty and wet and would ruin a person's floor. Making a mess is just being a poor guest and I would never again invite that person into my home. Very odd as I have many friends of varied background and not one of them is ok with wearing outdoor shoes in the house.
