Ladies of Lemmy, how common is it for women to have foot fetishes like some men do?

Personally, I don't get it. Foot rub sounds nice, but like not THAT nice. But I posted on a dermatology sub once and my DM's blew up asking my gender. Just from dudes though. Are there some women who are perhaps more quietly excited by feet though? Random thought as I sit here grinding off my cracked heels...
