I love how Danner boots fit and feel, I have a pair of uninsulated Danner Pronghorn boots, and I used to wear Danners for a job I had. My only real complaint with them is they don't hold up very well. For the cost they seem to wear out quickly.
I would echo Pointer here. I wouldn't go past 200 grams of insulation in a boot. The insulation makes the boots fit tighter it seems to me. Makes it harder to fit in the wool socks unless you buy a larger size boot.
