Coworker comes into work barefoot?

I've brought it up to the manager repeatedly and she does nothing. Now I want to report it to HR because not only is it disgusting, but I don't like her. She is a SALES LEAD and she's doing this behavior?
Would that be a stupid reason to call?
Yes that's a dumb reason to call
No, that's nasty u should definitely call
