What is the appeal of foot fetishes?

[venomrcrush]

Long story short, I ve been working on a comic where all of the people have fetish related abilities that are linked to their superpowers. However when it comes to representing fot fetishes, I dont know how to go about it. Is it correct to have feet undergo expanding or shrinking processes? Are feet supposed to look "pretty" or "extremely mangled" for best effects? I saw an episode on king of the hill where Peggy Hills feet were being used for a foot fetish website and the Guy who recorded her feet in action commented that people like it when she rubs them around in messy things like corn as opposed to pretty things like flowers, and also that bad smelling feet were better.

So if i were to create a person that could magically transform the ground or something she kicks and create any messy fluid substance around her feet, like mud or mashed potatoes, would that be step in the right direction?

Am I supposed to have them use their feet as often as possible? Like, should I create an armless character thats forced to use their feet for everything?

Also does it better to use a male or a female for this?
