You are standing in switch. Your back foot is on the outer edge of the tail at a 45 degree angle, heel completely hanging. Your front foot is near the bolts, closer to the center, toe hanging.

Snap a switch backside pop shove‑it, at the same time kicking the board with your back leg, like for an inward heelflip.

The board does a heelflip and 180 rotation. When the board completes the heelflip, which will generally coincide with the shove-it part of the trick — catch it and land. Ride away in switch.
