Someone who is fascinated about touching people's feet, but not as a fetish. They usually have beginner-level knowledge on the anatomy of the human foot and can also give great foot massages.
My sister's boyfriend is kind of a creep about her feet, like an armchair podiatrist.
A lower-extremity doctor who has such an acute foot-fetish dat he wants to do da ol' bouncy-bouncy wif any lady he examines who has attractive tootsies.
Hot chick: Some folks in this town despise our local podiatryst and won't go to him, but I don't mind having sex wif him 'cuz then he treats me for free.
