RicB: Okay, now about stance. First I should make clear that I'm not struggling with my stance. I do think that there is room for improvement in my footbed and boot though, even though I feel this is the best skiing boot I've ever owned.
DM : Fine tuning stance is always a good thing.
RicB: Something I had forgotten about because I quit doing it when I started tai-chi that has some relevance is an off season exercise that I do, one leg knee bends on a balance board. The board I use is one that is adjustable. There are three settings and I use the loosest one, but there is still some resistance to it tipping. Foot placement is critical for me. Centered is best, offset to the little toe side second best, worst for balance is offset to the big toe side as this seems to keep me from finding that platform you speak of under the ball of the foot.
DM: Be careful here. You want to initiate the instability you are feeling. I am not sure which balance board you are using. But let me caution you that the platform you need to develop in skiing is usually very different from the one legged balance exercises most people try to use for improving balance in skiing. I am getting to this soon. It should all make more sense then. Stance comes first because you need good stance to make the platform work.
RicB: also critical is upperbody being stacked correctly over the hips and feet. If I tip my hips or fold at the waist my balance will be compromised. If the foot is to far fore or aft it really affects balance also. This allows too much dorsi/plantar fexion of the ankle and it gets very hard to maintain balance. Maybe like soft boots? Do 3 sets of 20 of these and you will find a good stance or quit. Even on solid ground it can be challenging.
DM: You are absolutely right. Seeming small deviations can have a huge affect on stance. It takes a real effort to get it right and then keep the feeling. The rule here is practice to the nth power.
RicB: So I played with your tasks this morning. What I found was that my current footbed had the greatest effect on my stance, in or out of my boot. I never would have guessed that, but I never skied these with out the footbed. My older footbed felt better in and out of my boot. Both were made by the same person, but the new one has more ramp angle.
DM: Let me stress that one should never assume anything.
RicB: My atomic boot (last years 9.5 ride with atomic race boot injected foam bladder) does have a boot board. This covers the plates that the heel and toe pieces connect to and give a flat surface for the foot. There is probably about 2-3 mm ramp angle built into this board.
DM: I think it may be a bit more than 3 degrees (that is what we go by). I had a heck of a time convincing the Austrians to drop the ramp angle. By the way they thought it was a good idea to abduct the feet (turn them out at the forefoot). I didn’t agree and still don’t. In a single word it is DUMB!
