I have been wearing a pair of Mountain Extremes non insulated for the past 2 years. I have never had a blister or hot spots form these boots tired feet yes after miles of backpack hunting. One thing I do that maybe different than most is- 1) I don't lace up too tight, 2) I don't lace up the 2...
I wear the 145's a lot for working as well as hunting. I wear over the calf socks that I pull over 145's and that makes up the difference in the length. I actually like the short design to make them easy to get off in a couple seconds.
