A stance is about balance and control

A surfboard is narrow, so a surfer stands with one foot nearer the nose and the other near the tail rather than facing straight ahead. The front foot helps keep the board balanced and guides its direction; pressure from the back foot helps steer and turn. Which foot feels natural in front is a matter of preference, not a reliable clue to whether someone is right- or left-handed.

The labels “regular” and “goofy” make that preference easy to name. They’re also used in skateboarding and snowboarding, where riders likewise stand sideways on a board. The terms describe a stance, not a different kind of board or a different level of skill.

How a cartoon supplied the odd name

The name “goofy” is commonly traced to Disney’s Goofy riding a surfboard with his right foot forward in a cartoon. That image gave a memorable label to a stance surfers already needed to describe. “Regular” became the contrasting name for left-foot-forward riding.

There’s no special maneuver or disadvantage built into a goofy stance: a surfer can ride waves from either position. The lasting consequence of the cartoon is mostly linguistic—an animated character helped make “goofy” the everyday term for which foot a rider puts forward.
