Justin A.wrote a review of K2 Thraxis Boa Snowbaord Boot - Men's on November 30, 2009
I have yet to get out on the slopes with these on, but around the house they seem very nice. The triple boa setup lets you really dial them in. They boa wires on the outside of the boot that adjust the outer shell tightness (upper ankle and top of foot) are actually somewhat intertwined, so you kind of bring them to adjustment at the same time. Boots are light and seem well constructed. Very pricy though...but consider that if you are comfortable, you will ride much longer and harder.
