I agree with Terry, proper alignment comes from the waist up doesn't really matter where your feet are at or which direction your toes are pointing.
I hadn't really paid much attention to either, until I read Fred's article in the Dec/Jan issue of TBM. I've alway's been a rover, even with my compound bows. I try to practice shots from my knee's, squatting, standing, behind me, or whatever scenario I can come up with that might mimic a real life opportunity at game.
After reading Fred's article and having a buddy watch me shoot several shot's from varying position's, I do bend, twist, or whatever it takes to get my shoulder's aligned with my target.
Short point long story, the position of your feet is not nearly as important as the position of your upper body.
