The skier with a greater range of motion in the ankle can continue to press harder against the cuff to flex it.....with ankle movement....and won't find the knee taking over the task at hand.
do we have to agree with the above quote? and this is not opposite in any way simply a different interpretation of where the "hall of funny walks" movements in skiing come from. that quote implies that the skier is able to get the leg into the front of the boot using body english. bode miller can, everyone else out there better get their fore/aft balance figured out.
the knee joint does not take control of anything, instead the skier throws whatever they have to get control over the ski, drop their ass to bring the heel back to the snow, bend at the waist, tip their head, rotate the upper body, burn up their quads, lean in, stem the outside ski, etc. the kinetic chain gets used for compensation, but the transmission is the ankle joint.
more typical scenario would go like this; the skier with low or limited ankle ROM would attempt to press the shin into the front of the boot. if the boot is stiffer and more upright the limited ROM guy can drive the ski via the front of the boot. however if the boot has soft forward flex, or higher degree of forward lean, the skier will "use up" the available ankle ROM without being able to pressure the front of the boot to drive the ski. the results from there can vary depending on the athletic ability of the skier. in some cases when the ROM is maxed, the heel is levered off the bottom of the boot and the skier sensing this drops his ass to get the foot back to the earth. you might also see this skier with their ass dropped and bent over at the waist to try to get to the front of the boot. this skier may also complain of burning balls of the feet, tired quadraceps, etc.
the same scenario messes with the skier with excessive ankle ROM. the boot never stops moving in forward flex if the boot is too soft or has too much forward lean. you see this skier looking like a tele skier, and also throwing all sorts of body english at the ski to maintain control. you will see skiers with sway backed stance, stemming to start the turn, etc. without reduced ramp angle and stiff support from the shell, this skier has a lower leg in the boot like a frictionless joystick, and is constantly fighting to find the sweet spot.
so fore aft balance focused on the ankle joint is the answer. bootboard ramp angle combined with cuff/spoiler forward lean, combined with boot closure to the lower leg, combined with the stiffness of the shell material.
for your solution, revisit your set-up. bootboard angle, cuff FL angle, delta angle (outsole of boot or ski), shin contact (tongue shim, eliminator tongue, FL wedge, Booster strap), and shell hardness. and put the fricking rivets back into the spine of your boot where they belong!!!
