Hmm... let me think. I've known 83,000 people, so yes for the most part most of the fetishes were guy-only. Here are the exceptions:
I used to have a friend Robin in high school, and she definitely had a fetish for tickling other girl's feet. I don't think it was sexual, though, more like a dominance thing, as she was all about the taunting: "Ah, you're down and laughing like a little schoolgirl."
I had a friend Helen who loved having her feet massaged, rubbed, sucked and so forth. (Though not tickled.)
And I had a friend Jennifer who definitely had a foot fetish, both ways: she was often barefoot, and she always wanted to tickle male or female feet.
I also knew a ticklee with a foot fetish, a girl who only liked being tickled, but who was always paying attention to the shoes and feet of everyone around her. Like, she would notice if someone walked pigeon-toed or knock-kneed or something.
Oh, and I almost forgot Amanda. Amanda is probably the only one with a true foot fetish as defined clinically in DSM-IV. Amanda used to fantasize about feet on her breasts and between her legs, and if she was with someone who wasn't into feet, she'd simply close her eyes and fantasize kinky stuff while they were in bed together. (She abhors giving or getting tickles, though.)
