We’ve been doing this, for years.
I bought inexpensice slippers, years ago - yeah...probably MIC - to keep by the door, if someone insists on wearing shoes/slippers, in the house.
I have a taped off area, about 6’ past the door, on the inside, where you cannot wear any outdoor shoes, past the tape. (For the littles, who forget to take their shoes off, outside.)
I started with the outdoor shoes in January or February when I saw videos of the CCP spraying down streets.
Some other cultures have always done this, like the Chinese. Hmmmm...
