BTW I remember skiing at -40. I had the hill practically to myself. I wore a parka touque and scarf (around head and face) and goggles and farmer-john snowmobile pants and down mitts. My toes were the only cold part of me. Why don't they make warmer high performance ski boots?
I may get flamed on this one, but I'm pretty sure that warm high performance ski boots are an oxymoron. It seems to me as though they're diametrically opposite concepts. For starters, how warm can hard plastic shells be? I know they're supposed to be better now with the different plastics in different parts of the shell technique, but still...Secondly, in order to achieve that performance fit (roughly being able to fit 1 finger between the heel and shell of the boot when being shell fit), something must be compromised. The firm wrap of a well fit shell puts some serious pressure on the circulatory system of the foot, which isn't really designed very well for ski boots to begin with (large network of veins and arteries running across the top of the foot).
The circulation systems of people differ as well. Some have no problem staying warm in the harshest of conditions, while others get cold feet on 40 degree days (yours truly). Other variables such as what someone had for breakfast, length of chair rides, time spent standing around (at lineup, for example), and the amount of pressure the buckles are exerting on the forefoot can have drastic effects on the warmth of the foot.
Interestingly, my right foot tends to stay much warmer while snowboarding, while the left one (my front foot) goes warm/cold depending on how much I loosen the binding straps on the lift.
I should disclose that both my ski and snowboard boots are miniscule even when compared to my already small street shoes, although they are not 'too small' by any means.
