So you want to know how to ollie? Be warned, it’s not for the faint of heart, and a lot of people have tried and failed and tried some more and still failed and then eventually thrown their boards into a wall out of frustration (I have no idea who those people are). It’s by no means an easy skateboard trick, but if you want to know how to ollie, start with these simple tips:

Position your front foot near the middle and your back foot on the tail – The best position is for the ball of your back foot to be slightly hanging off, and the front foot more towards the middle. The position of the front foot can change, however, depending on how much air you want to get: if you’re planning on doing a monster jump, move the front foot closer to the back; if you’re just hopping a little bit, move it closer to the front of the board itself. Beware though, the closer you move it towards the back foot, the harder the trick is to perform.
After you’ve properly applied a burst of force to the tail, the top-side of your front foot’s toe should start dragging up your board almost automatically. Eventually, the higher you are able to bring your front foot during lift will determine the apex of your ollie, so work gradually towards lifting your front foot as high as your body allows. Skateboarders who record the highest ollies usually (somehow manage to!) bring their feet higher than their hips!
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.
