How can I land a kickflip on a skateboard?

You have to level yu board out and flick with the board, follow the whole board with your body and don't sissy out. The reason your back foot is landing and not your front foot is because your flicking hte front foot out way to much and your not giving it enough time to land back on the board. Quickly flick the board with your foot off the "pocket" of the nose, and flick it and while in air trying catching the board back with your front foot and back foot successfully landing it. You have to put 100% into the trick to commit you can't sissy out and put all your concentration in in your backfoot or only popping, level out with your board.
