F/A pressure

post #1 of 6
Thread Starter 
Skiers talk about pressure mangement. 50/50 or 10/90. What about fore/aft pressure management during a turn or in the air? Even when you are centered over your CM there is a continous change of F/A pressure on the skis.

fore / aft and ball of foot mounting?

Am I wrong in thinking your binding mount position has a huge impact on how much you need to deal with fore aft balance?. I read about the ball of foot (bof) mounting system, paid attention to it, and now realize why I have to center differently depending on where the binding is mounted. My volkls and stocklis are mounted rearward of the bof, while my dynastars are mounted centered on my bof. My dynastars allow me to be relaxed and centered on any pitch and any snow condition (spinning 180s/360s while keeping the skis on the snow is also easy). When I'm on my volkls or stocklis I need to be aware of not getting in the backseat in powder, and on steeps I feel I have to pressure my tips a bit to properly initiate the turn.
Is this just bad technique, bad habits, or is there really something to this bof mounting.
Also, what is better for all mountain & off piste skiing?, mounted a bit to the rear (bof) so you have to keep yourself forward?, or mounted centered (bof) so your always centered without effort?.
Or should you just mount the way the manufacturer marks the ski and accept skiing the way the manufacture thinks you should ski their ski?.
I would love a disscusion on this from some instructors. Thanks

Stand in balance. Where's the pressure? That's it. Although, there can be some focus points that will help with the creating angles.-----Wigs

I'll offer another viewpoint here, especially with regards to high angle carving. When the upper body (pelvis included) drops into the turn the skis are quite literally uphill from the CM. Assuming you keep your CM balanced the skis can slice right around it in a beautiful arc. If so, the pressure will move from slightly in front of the arch (at the beginning of the turn) to slightly behind the arch (at the end of the turn). Its a subtle feeling but when you get a feel for it you'll recognize those WOW type of turns just by the movement of pressure fore and aft of the arch.

Very good question. Once you achieve a dynamically balanced position on your skis, the body is stable and you are able "toggle" your skis under you at will (as Max501 describes). This is used not only on carved turns on groomed terrain, but on bumps and ungroomed terrain. It is done by either opening or closing your ankle to promote pressure control either on the ski tips, tails or along the whole length of the ski without loosing contact with the tongue of the boot.

An example is while skiing deep slushy snow that is "sticky". If you pressure the tip of the ski too much, it willstart to stall out as suction builds up. To keep the ski gliding well you can either lean back, which is not a good idea, or you can flex the ankle and press the tail of the ski down, which keeps the shin and tongue contact. When skiing deep snow off piste, I do the same thing if I feel the ski wanting to dive.

On Ice, I open the ankle slightly of the outside ski to keep the tip of the ski engaged through the turn.

All movements should be progressive weather it is for/aft or foot to foot pressure control.

There really is something to being properly balanced on the ski. You've figured out what it is. When a skier is out of balance it takes larger movements and more effort to accomplish the same outcome. I wouldn't call it poor technque. It's doing what's needed to get the job done. As alignment and balance issues are addressed skiing gets easier and more efficient.
