if the question was about longer manuals... others have given some good advice so far
slight stomp into it helps, then get your foot in the most comfortable spot to balance the most easiest. (you can find this by just standing still and lifting your front wheels and finding the spot where your particular board/trucks/wheels setup feels most natural to keep your balance for a longer time) ,,looking ahead helps sometimes,, as youre getting farther into your manny, make foot adjustments to get more comfortable for going the distance manualing the whole sidewalk block in front of your house.
