Look at the averages, if you slide more often with your left foot in front, set up the board regular. Another method is to place your stronger leg in back because you will be using it for turning motions. In the end, it all comes down to how comfortable it feels. Next comes the stance on the board. For beginning snowboarders, a slight turn of the front binding toward the nose of the board and the back binding with a little less turn is recommended.
Most bindings have numbers on the inside to determine the angle in degrees.
Make sure when you strap into the board that your toes don t hang over the edge too much. Again, try and stand on the board and adjust the bindings, so that you are comfortable. Boots are the often-overlooked component of snowboarding. A good snowboard boot, no Sorels is recommended for beginners. The boot should fit snug around your ankle, make sure your pants are out of the boot.
