Ramp angle

[mntlion]

sounds like an interesting study, except that it sounds like it was performed on a level platform. The vast majority of alpine skiing is done on downward sloped surfaces...

and where the skis are mounted front to back, how the ski flexes (soft tip/stiff tail), bindings angle, etc

but it is a starting point...

most of the time you can just add a shim to the back of the boots shell, they are usually 3-6 inches long and tapered. Will push you 5-20mm forward, as measured from the top of the boot.

You also have the liner to help pad and even out the shim, adn they are just plastic, grind as needed

ok so how do you decrease forward lean in a boot that doesnt have adjustment ?

XXX-er: to make a boot more upright then?

depends where on the boot/leg you are getting pushed forward from.

1) boot top only

heat and bend back the upper cuff, or grind it lower

2) solious muscle (sp)

grind shell material to make more room, (usually the upper part of the boot, and not the lower, but can be either) and make sure that the liner is not pushing and it is the shell for sure (so try the boot with a soft, floppy liner like an intuition or old packed out race liner)

3) achillies tendon area

grind a 10-20mm wide channel up the back of the lower shell to allow the tendon to sit all the way back in the shell.
grind a notch in the back

Muted is right here, the problem isn't ramp or lack of ramp necessarily, its how variable ramp can be depending on the binding type, and even on the same binding depending on boot sole length. Binding ramp was never designed as a performance enhancing feature, it is there to make room for the ski brake mechanism in the heel piece. It would be far better if all bindings came with a flat ramp, removing this element of variability, and then ramp and forward lean could just be adjusted if necessary from the boot. Of course, it would also make sense if bindings had a similar hole pattern, but don't hold your breath for either of these.

There was supposed to be an on hill follow up but I haven't heard from her. I kind of thing she didn't find any patterns to work from and let it slide or went back to re think the approach. I'm not sure.
