You guys laugh but I went out with my buddy who is riding a 162 Burton Bullet trad. camber deck.. We switched up because I wanted him to try a rocker and holy fuck.. he had a ridiculous setback(max. setback you can go) with his feet as close together as possible and a 0/0 degree stance, and get this.. A HUGE set back to the heel side (so much that his heels would drag on carves, but his toes were bearely even at the edge..
Some people just have absolutely no Idea how what they are doing.. He's been riding like that for years
Stranger things can be seen. I had a student who was severely pigeon toed and his toes literally pointed inward about -15/15. He physically could not ride duck or anything approaching a 0/0. We tried a few things from -9/12 and finally found a forward stance with the front foot at 3 and the back foot about 21 worked best for his condition. There are lots of medical issues out there and you will see some pretty strange shit but hey, whatever works and gets them on the snow having fun.
That was actually why he had a 0/0.. But the heel/tail setbacks were just strange haha
