Always energetic, Andrew Cannon is here to teach you a little something about wallie boardslides. First find a ledge with some room around it to work with, because you are going to need to come at it from a pretty big angle -- not exactly a 90 degree angle, and definitely not parallel. Depending on the size of the ledge, you may hit only two wheels before locking into a boardslide or you may hit all four. Watch the pro stomp a few and let Cannon break it down Step By Step.
