Why do boys like the smell of girl's feet?

There is a thing called a foot fetish,which is very common especially in male's. I don't have a foot fetish,and I know i'm not missing out on anything. A foot fetish is a sexual attraction to the feet. Usually the feet of a female. Girl's think of foot fetish boy's as "Creep's" or "Weirdo's" and I agree with them. Some has a fetish,and some have disgust. Which I have disgust.
