Why Foot Fetish?

I was reading a thread recently and I now want to know, why do people have a fetish for feet and/or toes? There are specific websites dealing with this fetish and I find it really bizaare!

You walk on your feet every day of your life. You keep your feet in smelly as shit shoes and socks. Now why would a person find this attractive? I guess a similar thing could be said of genitals but hey...

Anyone here with a foot fetish wanna speak up?

Feet fetishists are brain damaged.

This thread sucks, I'm off to watch some guro hentai.
