boots
I've had Pronghorns, as well as several of the higher end American made Danners, still have a pair of their Canadiennes (all leather) that are 15 years old. Pronghorns will not perform in the mountains, not like a pair of dedicated mountain boots. On the other hand, Pronghorns are like sneakers right out of the box.... very comfortable. That said, I now use Zamberlans, I have the old 920 steeps. These boots will protect you like no flatland boot can. What do I mean? Well, you should not be able to pick up the boot and easily flex it in your hands, nor should you be able to twist it. Zamberlans, Lowas, Meindels, Kennetrecks, Crispis (I've had these on - excellent), Hanwags...... these type of boots will preserve your plantar fascia and prevent hypermobility in your foot and ankle that will prematurely fatigue you, and provide the required protection from stone bruises or worse.
I never select an insulated boot for western hunting, too heavy, too hot. It is very important to get proper socks, I wear Bridgedale wool hikers with a liner sock. The fit is precise, there are no blisters, and I am not cold. Pay attention to this detail, it is as important as your boots.
Lastly, if the fit is not precise, consider aftermarket insoles like Superfeet greens - I have had good luck with these tightening up sloppy (in the heels) Danners. The Zamberlans fit like they were sprayed on, so I just stick with factory.
