I have a 44.5/US11 pair I’m selling. I need a pair of insulated boots so I’m swapping for the Crispi Briksdal. The sole is stiffer than my Crispi Summit, and less rocker. I typically wear a 10.5, but for this boot I needed an 11. When you first put it on it feels full in the toe box, and then it like molds to your foot almost like memory foam. I don’t know how it does this, but it’s honestly really comfortable. If interested I’ll send pics.
It’s fairly stiff, but comfortable. Probably similar to the Crispi 3-4 flex. I tried on the Crispi Colorado and it seemed similar when I had one of each on.
