My Canadian counsins (Calgary) have this no-shoe habit and I experienced first as a teenager when they came to visit. My mom was offended/disgusted that they kept taking their shoes off by the door and walking around the house in socks. She thought it was slovenly (maybe becasue this was her SIL, my aunt :roll

. I simply asked them why and they explained that the snow and dirt that shoes track in Calgary is so filthy that it is a common custom. Very smart I thought and, even at 16 with no ideas about crawling babies, I could see the benefits. Now that I have my own household and kids, its a practice we also follow. The back of the house has a mudroom with a chair and big shoe cubby but most guests don't enter that way, they come through the front door. Most people ask if I would like them to remove their shoes (I think its a custom that is becoming much more common in urbane areas of the US) and I usually say "whatever you prefer." I do ask all kids who come over (for playdates) to remove their shoes because I know they will be going upstairs in to rooms with carpeting. We do have a dog and I hate thinking about what he tracks in but at least our not wearing shoes cuts down on some dirt and germs... I have actually been thinking of designing a little "foot bath" for him by the back door. Anyone ever seen one?
