Cuff alignment occurs at the pivot point of cuff to clog. The trailmap thing is basically a temp way of changing canting- ie the angle of your boot sole to ground which means angle of bottom of ski to surface Essentially you're levering the top of the boot to adjust the bottom.
Jamming maps in the medial side, between cuff/liner, will put you more on inside edge Like a thick outside cant. Putting maps on lateral side will lower outside edge like a thick inside cant.
If boots are really sloppy and have a lot of room it will require a lot more maps or may not work.
I don't agree with you Tog. If you are balanced on your edges the boot planing only changes the platform angle. If you stuff trail maps you are pushing the tibia or fibula, but the pivot point will not be the edge, more likely somewhere inside the foot joints, i.e. pretty close to where cuff alignment would be done.
If want to play with the platform angle it's much better to tape some shims to the bottom of the boots.
Well, what's the point of cuff alignment?
- to make sure the curve of the lower leg doesn't push your boot to one side or the other. That affects the sole.
Plenty of race boots had no cuff alignment, so what did they do? Grind the soles, ie cant.
The trail map thing is yes, technically alignment by cuff. However, the point of cuff alignment as an adjustment in a boot is to align the boot to your leg so that your leg doesn't influence the sole of the boot. This is just the opposite.
You're not going to push the tibia with the boot, the tibia will push the boot. This is partly the old argument of "canting to push the knee in line" or "canting leaving the knee where it is and making the soles flat". As far as I know, there is no definitive answer to this, one sees what works. If you are way out though, there is no way you're pushing the knee around.
