Unattractive girl but pristine feet

I know a girl who is at best a 6/10 but her feet are divine, and I've seen girls who are bombshells but have the ugliest feet you could ever lay your eyes on.

The girl I know is half hispanic and half filipino and she has these cute light tan feet. She doesn't paint her toes, but she really takes care of her feet, and I have had the privilege of giving her a foot massage when we went out to a convention together.

Is there a reason most "hot" girls have ugly feet, even in pr0n settings where attractiveness is key.
