What is the appeal of foot fetishes?

And then there's the shoe fetish, which is somewhat related -- I love high-heeled shoes on women, and definitely not for "crushing" purposes or anything like that, just for going about normal activities. I find it extremely appealing if a TG or "increased beauty" transformation includes flat shoes changing into heels (or high-heeled shoes changing style into something sexier, e.g., plain pumps becoming stripper-type platform heels). I find it totally awesome if the transformation also includes a "curse" that forces the subject into high-heeled shoes permanently.
