Great that you're working on fixing your boot. That will be a great start to give you better support.
Alignment issues often come from muscle imbalances and how well your joints are moving. So with right hip/knee/ankle issues, what I typically see is weakness in the right glute med (inner butt muscle and hip stabilizer), along with a tight IT band and weak inner quad.
I would look at your posture, joint mobility, lower body balance, and check for muscle imbalances to determine a conditioning program that will correct the compensations you're having.
The knee strain that you're feeling on the right side. Where is the strain? Along the front? The inside of your knee?
Hi drjen, thanks for responding. It's been inside the knee.
I did go and get an alignment assessment, and that resulted in a small adjustment to my footbed and then a degree of canting on the right side. First day out, turn symmetry was vastly improved and the challenges I have felt on that side were pretty much gone. I also just installed booster straps - my tibia bow outward some on both sides, and cuff fit has been challenging. My fitter used a booster during alignment to make sure we weren't missing any compensation.
I need more time on the hill to see what remains, if anything. My offseason fitness is almost 100% mountain biking plus yoga (doing more yoga year round). The MTB aspect has been a revelation for ski training and stands on its own - I think there is a huge benefit to tactical downhill work year round, and the fitness benefits on the uphill side are excellent. My canting issue shows up in MTB, too, so I probably have more $$$ to spend .
Will report back, but I should have done the additional alignment work two seasons ago.
