It also seems quite dangerous to take them off- depending on the home. Some hoarders, drug addicted situations have needles, glass shards and razor blades in the debris on the floor. How do they handle hoarders in japan?

Obviously, it depends on the context once the front door opens to you

But - the context changes from room to room? Clean shared flat- messy druggy room with collapsed overdose person in it? This.. this whole situation makes no sense.. Have helper boots with a "condom-wrapper" if you are afraid of cleanliness - but keep the boots on at all times.
