Christy Turn - A turn done on skis with a skidding phase. Double Poling - Using both poles at the same time to thrust yourself forward. Flex - The amount of bending resistance the ski has.

Header - a face-first fall into the snow. Kick Turn - A way to turn in the opposite direction by kicking one ski to a 180 degree position and following it by the other ski. New Nordic Norm (NNN) - A boot and binding system that is known for it's comfortable flex and ski control. It has a short, metal rod in the toe of the boot sole and a clip-in binding that it attaches to.

Both are applied on different areas of a ski's base. Width - The distance from ski edge to ski edge, which is measured at the ski's narrowest part. The wider the skis, the more stable and easier they are to control. Where as the narrower skis tend to be faster.
