I went surfing earlier this week. (The proper way. At a beach, not behind a boat.) It was awesome! I ski RFF and ended up the same way on the surf board. Didn't put much thought into it, that's just the way it happened. Apparently this is "goofy-footed" in the surf world. It worked pretty well for me. The direction of the wave meant I was on my toes rather than on my heels which felt pretty automatic.
In skiing the front foot dominates. In surfing apparently this is not necessarily the case. I could be wrong about this; I'm a complete noob at surfing. For those of you that surf, do you ski and surf with the same foot forward?
