I don't know if it is right to walk around the house in bare feet

In what respect would it not be "all right"? Health? Hygiene? Something else?

Of course, if someone else owns the house and doesn't want you in your bare feet, then that's a whole other issue.

EDIT: I realize you are 11 years old and have posted about being nude in your house when you have a younger sister. https://www.askmehelpdesk.com/personal-growth/im-eleven-old-male-needs-parents-like-being-nude-608599.html

Your parents apparently expect you to remain clothed and that includes shoes.

What exactly is the issue here?
