I pretty much stopped the shin pain by the corrections in my skiing. Since a lot of these are new skills, every so often I fall into my bad habits (mucho years of practicing movements that no longer apply due to new technology) and the pain is back.
I don't think I flex my boots much at all anymore. As these new skills get ingrained in my skiing, there should be less and less pain. As soon as I start to feel a little pain it reminds me to correct my movements.
What movement you are probably now asking...
On older straight skis I had to drive the knee forward in order to get the boot to drive the shovel of the ski to bend. (see thread on skiing from the shovel) This put a lot of pressure on the shins, flexed the boot some and made the instep of my boot jam into the top of my foot. I also would pull my knees up along with my ankles and almost lift my toes to unweight my skis and initiate my turns. (again older styles) this Lifting of the toes and pulling up of the knees at the same time put a great deal of tension on the front muscles of the shin. now stretched out and impact on the bump or into the steeps was almost like getting a charlie horse, I think this was the source of the pain.
Since then I have learned to lead my turns with my downhill knee/leg. This stopped me from "popping up the hill" and lifting my knees and legs. Instead it forced me to move my CM down the hill with little or now upward movement. This was/is now my "committed to the fall line" I mentioned in my earlier post. It is also my way of not leaning up the hill.
Then thinking as if your boots had a clock on them. 12:00 straight ahead, 10:00 left front 2:00 right front. I used to drive my knees forward 12:00 to pressure the tips of my skis and init the turns.
Now I use 10:00/2:00 positions, and only light pressure or contact only if you will, at these locations, I tip both skis at the same time and work on getting steering and adjusting my turn size. By not concentrating on where my weight is (how much on each ski) I find that my body will move and balance all the forces to keep me from getting pitched over my skis. Using the ankles' flexion instead to gently press the tips into following the terrain, and extending my legs to fill each "hole" in the terrain or to reach into the belly of the turn.
By using the ankles to maintain ski contact with the snow at all times Extension of the legs and small movements starting at the ankles to keep my CM centered over the skis, and moving down the hill, I found that I am much more relaxed and only making small adjustments through my turns. This fixed the "cramping, tension" pains I had in my shins. Like I said though, I still lapse into old habits.
Does that make sense?<FONT size="1">
