The left hand side of your body is always a fraction smaller than the right side. i.e. your right foot is bigger than your left foot. Thats why when you buy shoes always make sure you try both on so you get a comfortable fit. 
That's weird. I think my left foot is slightly bigger than the opposite one. That's why i use it as my pivotal foot. Kinda like Beckham-esque type of player really. No leftie please, no leftie...
