I have a pair of Mucks that are 7 years old. Not sure which model, but the only time my feet were cold in them was at a bitterly cold January Patriots game after 5+ hours outside (tailgate + game + walk to&from). Arctic sports. Highly suggested. I picked up a pair of cheap Red head neoprene boots @ Bass Pro as truck boots and they stay in the back of the vehicle from October 1 to May 1. I had to do an unplanned trip to our NH place because the power was out and my freeze alarm was dialing me. Drove up.....To add to this.....Our plow guy had a hydraulic line in his plow fail, so it was completely unplowed...Red heads and pair of wool socks out of my BOB....then a 1300 foot uphill walk with almost 18" of wet snow. Did fine. If you're going to be outside for brief periods the red heads are fine, but mucks if you're out in the weather.
