For all you wide-stance fellows, is there a secret? 15 years skating and I'm still learning how to stand.
Here is an experiment to explain why the wide stance works and why you don't need to scoop your foot up the griptape. It only really works with upturned noses.
Stand next to your board and snap the tail only. Notice that the board wants to make a backflip/summersault motion. In other words, the nose wants to rotate towards the tail.
During an ollie, the upturned noses act like a hook once the board is angled 90 degrees right after the snap. The upturned nose is then over-vert, like an overhang. At the same time, the vector of your front foot goes forward at ~ 45 degrees, wheras your board is actually trying to do the back-flip/overflip. Those two opposite forces, with your foot winning makes the board stick against your foot because your foot/leg/body is the stronger of the two forces.
