SHIFTING your WEIGHT!
As you ollie, you need to have just the right amount of speed so that you can, in the air, shift your weight onto that front foot. ALSO, it needs to slide onto the nose of the skateboard. This shouldn't actually be all that hard - your body should want to land on this foot. The trick is to have the right amount of speed going so that after you ollie, you can slide that front foot all the way to the nose and land on it with all of your weight.
Your back foot needs to just get up and out of the way. Rest it on the tail of your skateboard.
