Red Head 600 gram thinsulate /goretex. Had a pair of very expensive Rocky 1000 gram thinsulate goretex boots. They leaked and the soles turned to gum and litterally fell off.
The 600 gram Red Heads are as warm or warmer than the Rockies and dry.
Danner pronghorn uninsulated down to about 30 deg or so, below that Lacrosse Alpha 1000 gram thinsulate, I've had the Lacrosse about 2 mos and worn them maybe a dozen times, so far no complaints, the Danners I've had for a few years and they have held up well.
