I highly recommend Kenetrek Mountain Extremes. Expect a long break in period (mine took about 50 miles) but, you will be rewarded with a comfortable boot that wears really well. Mine have been on 2 CO elk hunts including a tough backpack hunt along with 4 deer hunts over the past two years. They have hunted in snow and rain on several occasions and still look almost new. I keep them well waxed and they have never leaked and have always kept my feet warm. They will be going back to CO again this year.
