If you want to get all scientific about it, one theory is that mirror neuron activation stiumulates the feet processing area of the somatosensory cortex which is in direct proximity to that for genitalia, causing an arousal response, and in some people for whatever reason thats more active and becomes a fetish.
Thats one theory, but doesn't explain why everyone doesn't have the fetish, so its probably something like some kind of behavioristic pairing of sexual arousal with feet, or something

You have a foot fetish. Have fun kissing some feet!
I honestly have no idea....if you ask me feet are made for walking around in the grass and sand, and for swimming ^_^
To each their own really, the brain decided for you :P Best be sensible about once you accepted it.
