How do you do an ollie on a skateboard?

It's gonna take a few days to get it, and havin a good tennis shoe on will help, you might want to work on the motion of your ollie, the popping of the tail and the movement of your foot should all be in one continuous motion, so once you pop your tail down and u feel it hit the ground u need to jump and as u jump slide your foot to the top of the board. keep practicing and you'll get it.
