i don't think Joss Whedon has a thing for feet. on Buffy there were only 3 or 4 barefoot scenes, and where the feet should be bare, there were socks or slippers. you don't know how many times i held my breath as willow put her feet into frame, only to see them with socks or slippers.
i had some great sole shots of cordelia, buffy and darla on DVD from the library, but i couldn't get screen caps from it. upsetting, really, cause they were to die for.
long story short, this is the most feet i've ever seen him show.
i should have the foot shots from serenity posted soon enough.
