360 Pop Shove-it
This trick is actually pretty tough. You ought to know how to do regular pop shove-its and at least be able to kickflip and stuff.
You'll have to try putting your feet a few different ways. The best way is to put your feet kind of like an ollie and scoot your front foot towards your back a bunch. The most important thing is to keep the board from flipping, so you don't land prematurely or overmaturely.
Hit your tail and swing your back foot back. Jump. You want to use the power in your back foot for it.
Try to shoot it around fast and grab it with your feet. You might have to jump forward to catch it like a 360 flip (if you can't do this trick, you might want to try a 360 flip.)
