Soo kinda late too but I like to give opinions. Yeah folks do fetishize big feet because it's kind of a unique and desirable trait for somone that likes to be trampled or just worshiping feet ~
More surface is more fun y'know?
I enjoy the fantasy of big feeted women because there's many hot dominant things they can do with their big feet.
Same for guys too. I just like things bigger I guess in my humble fetishist opinion.
