I have always advocated a playing stance that resembles the traditional Tai Chi position, that allows the player to shift the body's center of gravity forward and backward. There are many advantages to this system, and one of them is comfort. If you stand totally immobile for long periods there is far more stress on the lower legs and feet than if you are constantly moving.
Shifting your body gives you greater stamina because, among other things, it promotes good lower body circulation. There is a whole host of other advantages, but this particular one seems to pertain to the problem many thereminists have with standing for long periods of time.
As for footwear, I always play the theremin either in stocking feet or barefoot. I only wear shoes if I am playing in public.
....just my personal take on the situation.
