In some of my family member's household, we have to take off our shoes. I don't see a problem with it at all.

In Japan, people make a big deal out of it because they don't want any of the outside environment being tracked into their house. It's the same thing with their schools. The schools have shoes for the students to wear while their there because they want to have as clean of an environment as possible. I wish I went to a school like that. Sounds kinda cool.
