You've purchased a new snowboard and bindings separately, and now it's time to mount the bindings. Determining how far apart to set the bindings is a matter of performance and comfort.
Instructions
1. If you haven't determined which direction stance you ride, have someone push you forward--the first foot that you use to break your fall will be your front foot. Right foot forward is goofy, left is regular. Place the board on the floor in front of you accordingly.
2. Pretend you're about to ride and get into your snowboarding stance. You want your feet spaced comfortably, without being too close or too spread out. In general, stance width should be equal to or slightly wider than your shoulders, but comfort is most important. Feel it out and determine what width feels most natural.
3. Be sure that the snowboard is clean, where the bindings will be mounted. Clean off any dirt or dust.
4. Determine stance angle. Each binding can be mounted at different angles, depending upon your preference. The basic stance would entail angling each binding slightly toward the front of the board at 15 degrees or less. Consider less angle on the back foot. Place your boots in the binding to ensure that the stance angle prevents any toe drag--you want the boot centered on the board without hanging over.
5. Place the mounting plates into the binding so that the screws line up with the screw holes on the snowboard and screw in all mounting screws. Be sure to use any washers or included hardware.
6. Do a test, warm-up run the first time out on the slopes. If you're not comfortable with the angles or width of your stance, remount the bindings accordingly before riding anything more difficult.
