I own a pair of the Danners Pronghorn but they are only 800 grams. I have owned Rocky, LaCrosse, and a few other cheaper pairs and Danners are by far the best that I have owned. They are extremely comfortable and durable. As davidmil stated, they are by no means a COLD weather boot though. I will not by another brand of boot based on my experience that I as well as a couple of friends have had with Danner.

My only suggestion is stay away from Rocky. They are basically a one season boot if you are lucky. At least that has been my experience. I don't want to offend the Rocky faithful but spend the extra $40-50 and get a boot that will last you 4,5,or even more seasons.
