DISK ORIENTATION OPTIONS
If your boot size is in the middle of the recommended size
range for your binding size, position 4x4 disc with slots
parallel to edges for maximum stance width adjustment.
Otherwise, position disc with slots perpendicular to the
edges such that you can position the toe and heel of your
boot evenly over the center of the board.
