I'll quote you, "That's really interesting". I only have one pair on the 2045 and they are my least favorite Vibergs, mostly due to fit. And I'm not sure if it's that I could have sized down by a half or that like you, the last is not right for my foot. But when I wear them again, I am going to pay better attention to what you've stated. My 2030 boots feel just great.
