It looks simple but yet complicated and vice versa. It takes most weeks to months to learn n some even years but a lifetime of effort to be consistent and be perfect at it and able to go higher, faster and further. It is not a feat you achieve once and it can be thrown out of the window if you want to continue to skate well. I've know skateboarders who just does ollies, boned ollies, ollie north and ollie souths, fakie ollies, switch ollies and nollies and nothing else but everytime he's popping them over 3ft height and up ledges, over gaps and down stair sets or over handrails. So no one's gonna argue on that even though he's not bustin some new fangled pressure flip late flip revert or something. He gets mad street creds for those huge ollies.
A rushed take-off might be the problem here. Steps 2-4 of this trick tip could help you out. In order to make your feet “stick” to the board, you have to do the movement fluidly. But don’t stress yourself out! You should rather start with some preliminary exercises until you feel safe while ollieing. It is also important to pull your foot up to your board’s nose in a straight manner to prevent it from spinning.
If a skateboard deck is turned over to its design side, there are two complete T-shaped pieces of metal. This piece is attached to the skateboard deck with screws. The pin is a long piece of metal that is designed to turn the skateboard deck. Adjusting its tension affects the skateboard deck's turning sensitivity. Typically, longboards have looser tension than other skateboards to allow deeper turns.
