Take off your shoes?

It’s something that a lot of families think is a good idea, but I always figured it had to do with keeping the house clean. But it’s not something I’ve ever taken upon myself to do at school. Perhaps this medical reason is a good one. Plus, it’s easier to sit cross-legged in my chair without shoes (which I like). :D.
