I really like my Danner Pronghorns. Mine are 400 gram Thinsulate and they work well for both sitting and walking while hunting.
I had one pair and wore them out, bought another pair and still have them. I got a crazy good deal on the Meindl's so I bought them. After wearing the Meindl's and trying the Pronghorns back on, I guess my foot has changed a little and they don't fit as well.
I know for a long time I wore a size 11 and now my feet like size 12 better.
