Hey!
One of my fetishes, is when girl has only one shoe off. She may lost other, toook it off or her shoe could be stolen by someone.
Probably its started, when i saw that scene whe i was in primary school - one of girls fom my class lost her ballerina shoe hurrying to the toilet. But when she comes back, it was nowhere in sight. So, she spends rest of the day wearing her yellow socks, but only one dark green shoe.
I don't think that can be called a fetish in itself. Just a cute scenario that lends itself to a foot or sock fetish.
I would classify it under foot fetishes
