Women with big feet, how do you even find shoes?

I’m not trying to make fun or criticize, I am just curious. I have this friend and she can’t find shoes anywhere’s. She can if she’s lucky or she’ll have to find them online. Even online that won’t always have her size. People are shocked when they found her show size and yell, “DAMN you’re a size 12??!!! Girl you feet are BIG AF!”
I felt bad for her a bit but it is the truth so no sympathy. I mean she is TALL. She’s supposed to have bigger feet. I think she’s 5’8. I mean 12 is pretty HUGE for a woman. No offense.
How do you coop with people mocking you and teasing you about your shoe size and where do you get your shoes? Do your parents remind you about your big feet?
