I think it does keep at least some of the dirt outside. That said, we just had another pair of sports shoes stolen from outside our door just yesterday, so I'm a bit ticked with the whole thing. It really is customary here for everyone to remove their shoes, so there's no real question of needing to ask visitors to remove theirs. I think most visitors would see you removing yours, putting them on the rack, and then ask if they should do the same. I certainly would if I were visiting someone's house. Having generic slippers available for visitors is one way to get over the awkwardness, and people can continue to keep their feet hidden, warm, wear socks... whatever, but without wearing their dirty outdoor shoes into your house.

and that's my thesis on shoes for now!

other than that, welcome Brittany!
