How do I pull a kickflip

Skateboarding Tips and Tricks @ Skateboardshowroom.com

stay center of your board and pop that tail and flick moderately not too much flick!. still remain over the board (dont bail or get scared you wont get hurt) suck your legs up and when you see that grip tape slap it down and roll away smilin :)

Kick, slide you're foot all the way to the top corner, gently kick out.
They take ages to learn, but you'll get them

What I do is I put my foot between the truck bolts and the middle of the board(my foot is at an angle with my ball of my foot to my toes on board) then, ollie and slide your foot to the nose and flick the board in a "flipping" motion.
Do not be afraid to land or take your feet out of place.It is quite an easy trick once you get the hang of it. :)
