Do people use? Tootsies, piggies in reference to toes (this little piggy game), peds (in reference to feet in general, though that's not cute, I suppose). I don't know any others....my SO doesn't have cutesy names for my feet, though he says I have lollipop toes sometimes. >.<
I say "feets" and "toesies" sometimes. With my gf I call her "honeytoes" because her feet always naturally taste sweet to me (must be our bodies' chemicals).
