Takes their shoes off in the "entrance" (or mud room maybe, though I've never known anyone who calls it that) of the house, which is generally a small tiled area immediately inside any doors that lead to the outside. Shoes are left on the tile (or a mat / plastic shoe thing) and then folks walk without shoes from the entrance area into the rest of the house.
I think it's a good idea.
Is a "mud room" a Canadian thing?
Widely used term in New England in the US as well. For me, it's not a literal room but a tiled extension to the kitchen where I take off dirty shoes and so forth.
