It is IMPOSSIBLE for me to point my toes forward. If I try, my foot goes on this massive angle in the stirrup so when I rise, I'm just pushing off the outside of my foot which makes me roll my ankle in the stirrup. Resulting in a lot of pain. :( So I've stopped trying, it looks awful I know, but I've always ridden like that so I can make all the right cues to the horse and they've never misunderstood what I'm asking.
But that's just my wacky feet :)
