I'll throw in my 2 cents worth...
For the past 5 years I have been wearing a pair of Zamberlan 631 Civetta GT RR boots. They are the best boots I have ever worn for all outdoor activities! I have worn them for mountain hunting, backpacking, and upland hunting in Alaska, Colorado, Texas, Washington, and Wyoming. They provide excellent foot and ankle support on all types of terrain. If you want a taller boot then take a look at the Zamberlan 1012 Vioz Boot. It looks like it would be outstanding as well.
