Land at the same time – Again, this is probably silly to repeat, but you’d be surprised to find out how many people execute a successful jump, and then throw their hands up in the air to celebrate their new-found triumph, and forget the most important part: landing. The best position for your feet to be in is as close to the trucks as possible. Don’t land too close to the nose or tail, or you could end up breaking off those the board itself. Also, remember to bend your knees to absorb the jump. Don’t want to land straight-legged: that’s how kneecaps are destroyed.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
