I was looking for a solid pack boots as well for hunting in tree stands. I came across Hoffman's did some research and everything I read was positive, the nice thing is they are made in Kellogg, Idaho.
I happend to be working up in Kellogg so I stopped in to see them, very nice people. After talking to the young lady I purchased the Pro Series in 14" and I had them customize the boot with "Ankle Lock Stabilizer Strap" for more ankle support.
I have not received the boots yet because it take three weeks to build, I could have them do a rush order and get them in three days but don't need them for a few weeks.
When I get them I will post a review on these pack boots.
