Ray, I respectfully disagree! I am a perfect example as I am not a world cup level skier and do not have tree trunks for legs but ski quite happily in a Nordica Aggressor 150 as do a few others around here and we are all quite happy in them. There isn't alot of ankle flexion available in this boot and certainly not the full range of normal ankle flexion. So why then do we all prefer these boots over softer versions?...
When first skiing in a stiffer boot it takes time to learn these new flexion movements but once this occurs the benefits begin to shine brightly! Bob Barnes has a few great graphics and animations that demonstrate this. See the backpedalling through the bumps man and notice no ankle flexion and the arms extending forward to maintain balance.
Why would hands moving forward as hips move back be any more unstable than flexion sans boots? Remember this is not a "position" to stay or ski in, it is merely a place along a spectrum of movement.
To each his/her own but since discovering stiffer boots along time ago, my skiing has improved rather than suffered and if this was not instantly noticable I would still be in a softer boot!
This is one of the areas I am excited about exploring more with all the boot fitters. The fore/aft alignment is very important to skiing in balance and finding the optimum static position in our equipment is one key to this formula.
If we did not have these long lever arms attached to our feet I might agree with you more, however; since we do we need to control them and to do this we need to transfer leverage along their length to regulate turning and balance.
A crowbar transmits more leverage than a string of spaghetti. Something in between these two extremes is where we will find a happy medium between balancing and leveraging in a ski boot.
