This is interesting..
I wonder if anyone compiles this data in the boot fitting world? Doesn't seem like it.. I have long legs for my height, and a short torso. I've been fitted with and without heel lifts. Actually I've been fit in a ton of different ways based on the fitter, and none seem to ever be the same, just lots of trial and error, many times things go downhill not up. I also have to say that even after a ton of bootfitting in the past say 5 years, I still don't totally know what works for me in general, it all seems to be voodoo and magic sometimes haha. Right now in these current boots things are pretty good and include a heel lift, but would these rules apply in every boot? No idea! It's so frustrating.. I'd really love if there were a ton of measurements to make a better starting point for more of us, because so far from my experience, the general rules of thumb haven't worked well for me. My current setup came from a reference of a bootfitter from
@ride_ski, and the shop analyzes your weight distribution in boots during the fitting with a computer program as a starting point and goes from there. These boots have been my best so far for balance in my skiing, and have helped tremendously with issues I previously had with fore aft balance in bumps and difficult terrain etc.
