Riding backwards — on a board with your normally trailing foot in front, on twin-tip skis tails first. From a normal stance, every odd rotation (180, 540) lands you switch.
Switch means riding backwards — on a board with the foot in front that normally trails (a regular rider then leads with the right foot, a goofy rider with the left), on twin-tip skis with the tails leading. Why it isn't a party trick: every odd rotation swaps your stance. From a normal stance a 180 lands switch, and so does a 540 — without a solid switch you are left with full rotations only, like a 360 or a 720. The typical mistake is dropping it after the first wobble and perfecting your favourite direction instead. Yet switch is trainable, not talent: riding full runs switch on flat, empty terrain usually cracks it within a few sessions. What often gets missed: switch costs you the view behind you. Practise it where it's quiet, and glance over your shoulder before every turn.
