In this version of the heelflip, you want to set your feet up the same way you would for a kickflip. When you pop your board into the air, you make the same motion as with a kickflip, but you flick the board on the opposite corner (see photo). This makes the skateboard spin the opposite way from a kickflip. It's a fairly simple variant of the trick.
However, be careful - the kickflip is a more natural way for your board to want to spin. With this heelflip version, the board has a good chance of flipping up and nailing you in the groin. Sound like fun? Oh, it isn't.
