Last year I had custom insoles made for my feet by a ski alignment guy. I have a leg length discrepancy that has not been addressed in my boots or bindings. Up until recently, I've had wider powder skis, but I just picked up a frontside carver, and I think that made my alignment problems obvious.
The carvers, 170 cm Experience 88s skied pretty darn fast, 48 MPH according to ski tracks. Not that my intention was to go fast, but I found that at my fastest, the skis seemed fine and stable, I was more the one who was feeling nervous and so I hit the brakes.
The snow was firm and hard in the morning, and softened up in the sun on Mt. Hood. I noticed very quickly a problem I have not experienced with my 171 cm Atomic Access: My inside right ski edge and I think my inside left ski edge both started to engage while the skis were "flat" and I was trying to go straight. My left leg is shorter than my right, and I have much less balance on my left side.
I also noticed something else interesting. When I took a left turn, and my weight was mostly on my inside right edge, my skis were further apart and doing a slight pizza(ie. my skis were not parallel). When making a right turn, my weight was on my inside left edge, and my skis were parrallel and the turn felt good. Keep in mind it's my LEFT leg that's shorter and has poor proprioception.
So given this information, I have the following questions:
1) Does all of this info add up into the problem clearly being my leg length discrepancy and that I need shims or canted boots? I wondered if what I was noticing might have been related to a subconscious bias towards relying on my right leg, but this doesn't really seem to fit what I noticed. I recorded two videos which captured what I'm describing. Would it be helpful for you all to see them? I can post them in this thread.
2) I found both of my inside edges wanted to engage while going straight down a run, making for a tough ride. I've heard these skis talked about as being "squirrely" at high speeds. I'm wondering if what I noticed is more directly related to the alignment issue than anything else?
3) My skis felt stable even at high speeds today, but I wasn't feeling very secure on the skis at higher speeds. Could fixing the alignment issue cause these problems?
4) My old pair of skis have less of a sidecut are wider, and more powder oriented. Is this a good explanation for why this alignment issue wasn't as obvious before?
5) I notice when I turn right and my weight is on my inside left edge, I have difficulty maintaining the edge, and the ski slides sideways (only at higher speeds). Is this because of my lack of strength in my left leg? Or is this problem something that could be fixed with alignment work?
6) Finally, the alignment guy I saw in Portland wasn't sure if he could add shims to my boots given the specific boots I own(Full Tilt Originals)--which would be ideal because I now have multiple skis. Should I get that same guy to add shims to my set up before I leave town in two months? Or would it be way better to waiting until I get to Colorado so that I can go back to whoever I see if my shims need tweaking? Or would someone out in CO be able to easily adapt my shims from the guy here in Portland?
7) Is there any way I can make a temporary or even longer term home solution to this problem? I''m thinking adding thickness to the inside of my left boot would do the trick...
Lots of questions, and I appreciate any input you all could provide!
Thanks in advance,
