he posted some nice stuff that explained why for some turns you can actually feel the supinated foot being pressured & flipping in to pronation subsequently. (sorry my description is probably poor - but his was GOOD)
Disski, I thnk Fastman was talking about taking advantage of the natural mechanics of the foot in a turn and how that feels in the foot. The foot does respond to loading in certain ways. In the gait cycle, this is called a loading response and we do use this for balance feedback in skiing along with directing pressure to the inside edge of our ski. A loaded foot gives us our stable base of support in skiing, but the real question is how best to keep our foot in this state, and how much movement is needed or allowed for shock absorption and for medial ankle movement and pronation?
In the world of footbeds there is more than one school of thought on this from what I understand. Issues of hard or soft footbeds, no footbeds, or footbeds designed to allow for active foot loading and toe extention, can be confusing, and I don't think there is any one way that has real tested science to back it up. The only research for skiing I have been exsposed to was done by DavidM in canada, done in colaboration with the Human reasearch lab in Calgary. I think it is safe to say that there is more than one way to skin this cat, and the human being what it is will adapt. How much do we want it to adapt in skiing or how much do we want to allow it function naturaly in skiing?
Personaly I have moved away from hard footbeds to a half hard footbed that allows for more natural forefoot loading and pronation yet keeps my heel stabilized and my arch supported more to the rear. The footbed I use could be used in any type of footwear. Many might think this wrong for skiing, but I got hear after much tutelage, research, and experimening. Later ,RicB.
