Sorry for the slow reply.
I did see a "Harb Systems" alignment guy, who made me custom insoles which have greatly improved my skiing, I think.
I do have a leg length discrepancy, somewhere around or over a half inch. I haven't had a shim or anything put in, so that leg length discrepancy is still impacting my skiing.
When I talked about natural limitations, I meant that the left side of my body including my left leg are slightly less sensitive than the right side. The leg length discrepancy is a functional difference (due to atrophied muscles in my left hip, I believe). This has all been discussed with multiple physicians, etc, so no need to go into the medical diagnoses. This doesn't create huge functional problems for me. It does mean that my balance on my left leg is way worse than my right leg. It's also frustrating because it means that if I work out, I can feel my right leg becoming fatigued, but not so much with my left leg--there's less sensation there. Therefore, even though I am not currently working out or actively trying to improve my balance, I think there are limitations in terms of how far I can go, ie. my right and left side will never have equal strength or sensitivity.
I would like to work to improve my balance, strength, etc, and I do think this would improve my skiing. Any thoughts about this would be appreciated--and I'm happy to clarify anything that seems unclear.
I didn't say the OP has an alignment problem, and nothing he said indicates he does. He describes it as a physical limitation causing muscle weakness, andI think we can do him the service of believing him. I responded to his idea of correcting bad turns on one side by manipulating his ski tune rather than dealing with the problem more directly (which is actually a clever idea, but not likely to work).
I assumed he was familiar with his issue, and that one of the many things I threw out there would ring a bell for him. I admit that I got caught up in gear (tune) vs gear (boots) in talking about what he might do to find out what kinds of things people do to compensate for physical problems, but that's because I like talking about gear more than ski instructors, physical therapy, or yoga classes, all of which are at the top off my list of helpful approaches.
Uh... I fit boots. I coach skiers.(yes, you need coaching going by your avatar, even if your alignment is completely dialed in) Did you not understand that I agreed with what you said in post #18?
Once more. Given what we know about the OP, we have NO idea what's going on with his alignment. Or not as might be the case. Could be a leg length discrepancy... Who knows? You don't. I don't either. Sure.. Ask the OP if he's been checked. That's reasonable.
