What helps me (since I tend to do that also) is try to keep directly centered over the deck/bars and You just have to let it flow, when I try really hard to keep it up, It never goes as well as letting it "flow"
Where do you usaully keep your toes?! I tried to keep them on the deck, the bottom of the headtube, and the top. I either go over the bars or not high enough to keep the deck up
