Basic Cuff Alignment

For some reason cuff alignment has gone nuts. Years ago the basic most rudimentary understanding was put the leg in the middle of both sides of the top cuff of the boot. 

The left boot would normally be considered close to what you want to begin with. The footbeds should be in the boot, to stand on. When the cuff is touching the leg or pushing against the inside of the legs also called the medial side, that is called "cuff strong" or over powered.  The problem with over powering the leg with the cuff, is it pre-loads the big toe edge or inside edge of the ski, even in a straight run. If you try this from a straight run, both skis flat, and lift one foot/boot/ or ski off the snow; the ski immediately rails or you fall to the outside. So to balance and stay in a straight run on one leg, you have to push your leg, rotate the femur, inward which looks like you are pushing the knee against the over strong cuff or in toward the other leg. In fact that is exactly what happens. This makes the ski rail. and the upper body has to compensate as a result.

From your experience, what boot has the most efficient and effective cuff alignment adjustment mechanism?

The Head boots have a very good system of cuff adjustment on both sides of each boot. Sometimes in extreme cases even that doesn't go far enough. We are manufacturing our own adjustment rivets for those cases. It's really obvious in kids boots where there is little or no adjustability.
