I'm on my third pair of Hanwag Alaska GTX boots. I wore them on sheep, elk, antelope, and mule deer hunts last fall and they were excellent. They are extremely supportive and I never have foot problems with them. They are almost as stiff as plastic mountaineering boots, but way more comfortabel.
I have Hanwag Llhasa s and they are great. Not waterproof tho, just sno seal them and all is good! They re expensive but worth it i think. I wouldnt hesitate to buy any Hanwag product.
