I brought my boots in to get aligned last year....now I'm wondering if it was canted the correct way.
please excuse the crude drawings. The dimensions may be exaggerated, but I think it gets the point across. The first picture shows how my legs look when I'm standing comfortably with my feet fairly close together and ski boots on. The red line is a plumb bob line showing middle of my knees to the floor. My lower leg has a weird curvature to it - it goes outside then back in. You'll notice that in this position, my knees are directly over the center of my feet which is good, but this is too narrow of a stance for normal skiing.
The second picture (top right) shows me trying to get a nice hip-width stance for skiing. Keeping the cuff angle the same, you'll notice 2 things happen. 1. the outside of the boots come off the ground (if my legs were just hanging naturally with no weight on them) and 2. the center of my knees end up well inside of the middle of the foot. The result is that during my transitions and going straight, I have a tendency to track on my inside edges and my ski tracks converge at transition.
In the 3rd picture (lower left), the blue represents the cant added to form a new bottom of boot. The cant is put on the outside of the boot. This resolves the 2nd issue stated above. Now, during transition, I'm flat on my skis and my tracks don't converge like they used to. This is the adjustment I got done on my boots. However, it does not solve the issue of the knees being inside. I believe this may cause me to have A-frame issues as well.
In the last picture, this would be what it would be like if I got some cant on the inside of the boot. My knees would line up again over the middle of the foot. However, my upper leg would then not line up properly. Also, in a neutral position, I would be on my inside edges even more.
So what is the right way to cant? Did I get my boots canted the wrong way? Perhaps the last option is the right one and I just need to teach myself to keep the skis flat during transition. I would force myself to make it feel like I have a big ball between my legs. It would be awkward at first, but I can probably get used to it if I work on it.
