Tristan,
Finland gets a lot of snow in the wintertime. As a result they take off their shoes when entering someplace like a home, or an office. The practice continues even in the summer time. Here is a picture of the office front door on a typical morning.
A lot of homes and apartments even have small hallways as you enter the home for removing coats and shoes. The best part of this is that it means everyone is running around the office in his or her socks. Which on hardwood floors makes for some fun high speed cornering when you are in a hurry.
I may or may not have been seen sliding across the polished wood floors, arms wind milling like a madman.
