Open Question: How to tell if a girl has a foot fetish?

[feedcrawler]

How can I tell what girls in my school have a foot fetish? I know may be one girl really well but she will probably laugh and make fun of me if I tell her, and she has a bf so she would probably tell him and her friends also. Some others I don't know well but I am just wondering if they do or not. Are there any easy ways to tell without embarrasing myself?
