How does the day-to-day work of not wearing shoes in the house?

I have been reading a lot lately about not wearing outside shoes in the house and it interests me even more because I've been saving to re-carpet my whole house. It hits me every now and then about how to do things though, like, say I'm cooking all day on Sunday then need to take the trash out. I'm assuming it's change shoes, then say the grandkids stop by and want to go go for a bike ride? I'm assuming it's change shoes. I guess maybe what I'm asking is how many baskets by how many doors with how many pairs of slip-ons (both indoor and out) do I need?
