Jim...it really might be worth checking and here's why..
I think the wider ski is imparting more torque and if the upper cuff is loose or not simpatico with the upper leg, than you will "feel" sore or pressure points or hot spots.
For even as much as an ankle articulates in the boot, I'd rather think of it at least for my boot fitting, the ankle bones tip and push against the shell to contine the movement chain of events to turn the skis. If there's much movement around the ankle, you would be ankle sore fairly quicly. If you feel the pressure further up the leg, than I think somewhere the pressue may not be evenly spread along that side of the leg.
It's definetly a feel thing....keep those ankles snug and the upper cuff snugger, (ha)....has paid big benefits back to me.
Give ur another look Jim....start with the liner out and your' footbed in the shell and see how and where the ankles line up with the shape of the shells ankle pocket and upper cuff. With boots buckled (liners out) get in your ski stance, looking straight ahead and have someone check to see that your upper leg is centered in the shell.
Take pictures...oh yeah....then you could get all here to post their thoughts....I like it...An online analysis..how cool!
