bud, I completely agree with the importance of being properly aligned. I think in most cases, it would help tremendously.
However, I think you underestimate how much our natural tendencies have regarding the use of our legs, regardless of alignment. boot alignment can only bandaid our inperfect bodies. The fact is, it doesn't fix the problem...a problem people have dealt with all their lives. We don't have the perfect footbeds in our street shoes, or the canting strips on the bottom of our normal footwear. We have to deal with these on a daily basis, and our bodies naturally adjust and develop slightly different muscles so that we can walk and run normally. The result is one leg being better equipped to deal with certain situations than others. One leg is stronger than the other, one leg has better balance, one leg can make finer movements, etc. Also, there's just naturally a leg we like more, just like a natural hand (right/left) we use to do things. All these show up in skiing, whether you are aligned properly or not.
The point is, alignment is important to get the most out of your equipment, but don't expect alignment to fix everything. You will still have to deal with learning how to compensate for having certain preferences on one side of your body.
Can you back that statement up factually? or admit it is only your perception of the facts?
In many cases it does fix the problem if the problem is misalignment, and many if not most times, it is an alignment problem. I agree there are some cases where skiers have physiological issues unrelated to equipment whether that is muscular imbalances or asymmetric ranges of motion, or whatever. I have assessed thousands of skiers' alignment over the past twenty years so I have a pretty good grasp on the real life results of what I do.
Certainly, eliminating the easiest fixes first (proper alignment) will isolate and minimize any other issues one may have. Again it amazes me how many people seek to marginalize the benefits of proper alignment. It is because they are influenced by boot fitters or instructor/coaches/mentors who haven't got a clue about doing alignment work so they marginalize it to hide their ignorance and their customers/students believe them. Too bad.....
I doubt there is one elite skier who isn't either naturally aligned perfectly or has had his/her alignment dialed in. Top athletes spend a lot of effort to dial in their stance alignment! Why do you think this is?.... Why would anyone spend money on lessons/coaching without eliminating the number most important hurdle to skiing improvement? People spend a couple thousand bucks on skis and boots but cheap out on a couple hundred dollars for the final customization to optimize their skiing performance??? How much is your recreational time worth?
You have to ask yourself, am I skiing to look good in my outfit and be cool or just enjoy the fresh air or......do I really want to become a good skier?
The facts are in simple geometry. What exactly can happen in alignment? you can raise the inside/outside and fore/aft of the boot (canting). you can change the angle of the foot relative to the lower leg when it's in the boot (cuff alignment). You can fix foot support and raise inside/outside and fore/aft of the foot inside the boot (footbed and footboard). With the right combination of those 3, you can do quite a bit to get certain things lined up like knee to center of foot and proper fore/aft balance, etc.
However, the discrepancies between left/right side of body is not that simple. There can be many many differences, however slight they are, at the hips, knees, shoulders, anywhere. Can alignment fix the fact that my right fibula is curved slightly differently than my left fibula? Can alignment change the fact that if I sit down and stretch out a leg to one side, I can touch my right toe, but not my left due to different flexibility? Can alignment change the differences in my left/right hip joints? Also, my left foot pronates more than my right foot. A proper footbed can only help give the left foot some of the support it needs in a specific position, but it does not fix the problem. Our feet have 26 bones in them. All these play an important role in our balance. Our feet are constantly making minute adjustments to keep us standing up on 2 legs. The bottom of our feet are not static, they are constantly changing shape depending on how we pressure the feet. Unless the footbed can automatically and constantly adjust to that, there would be no way for the footbed to provide me with the proper support in all situations. The best we can do is create a footbed that provides decent support in most situations. The list of things that can't be fixed by alignment goes on. The human body is amazingly complex...its a joke to think that things can be fixed by just adding a few cant strips here and there.
Point is, alignment is helpful and useful and I recommend people to get it (I did it). Every little bit counts. But it is not the end all solution. There's no such thing as "perfect alignment" only "best alignment possible for a certain person". The differences in our physiques play a much bigger role in determining how we make our turns one way or the other. No amount of alignment is going to change the fact that my right leg is stronger, or that I have better balance on my right leg, or I have better control in my right leg. You don't think any of these things will creep into my skiing as long as I'm aligned properly? I guarantee I will play favorites regardless of how I'm aligned.
I still go back to the snowboard argument. Would you say that if you got a snowboarder properly aligned, all the sudden they would be just as comfortable riding switch as they do normal? I don't think so. Even at the highest levels, snowboarders still have a preference to which side they put out front. The same goes for skiing, there will always be a preference. The best we can do is realize the differences and train to reduce weaknesses on certain sides of our body and consciously make an effort to not let our preferences cause us to rely on one of our legs more than we should.
