After destroying my Kenetrek's last year I have been on quest for new boots. I, too, have a narrow foot.
I tried on a buch of boots at SCI in Vegas and ended up ordering Schnee's Granite boot to try. When it arrived it felt good initially, but after 2 days of indoor wear, no go. The went back.
Prior to my trip to Vegas I had tried a bunch of boots at Mountain Gear in Spokane. My gut told me to go back to my mountaineering days and order up the tried and true LaSportiva Makalu.
As I debated moving back to a heavy mountaineering boot I tried some of the Sierra Trading Post Lowa's with no luck and a few other boots along the way.
Two weeks ago I was in REI in Issaquah waiting for the pass to open and found some discontinued Lowa Mountain Expert GTX boots on a great sale. Amazingly they also fit my foot because they are constructed on a narrow last. Two weeks in and these look like keepers. 4 days ago my two pairs of Makalu's arrived from Moosejaw. The size 10 fits beautifully! I am likely going to keep both boots and will role with the LaSportiva's when long trips and heavy loads are on the menu. I also know from exeperience the LaSportiva will likely outlive any other serious backpacking boot on the market. My last pair carried me about 11 years and now my brother has worn them for about 4 years since I gave them to him.
I will not purchase another pair of 'hunting' boots. $400+ price tags and 4 years or less of life is not acceptable. I am not a guide or an outfitter. I expect boots to be worn out by those folks, but not by the average backpack hunter.
Finding a good boot - that fits well is a long process. Good luck to those out there with narrow feet, the options are few and the trial period can be long
