What ^ that guy said.
Fit is *everything* (once you're at a high-quality level that is).
I generally wear mountaineering boots b/c that's what/where I've most pushed my endurance. My cold weather boots are LaSportiva "Nepal Extremes" which are superb in every way. If it's really screaming cold outside I slip 'em into my Outdoor Research "Brooks Range" over-boots/gaiters. Then I'm gtg to temps way colder than i'll likely ever hunt in. I've never had a blister in them. Ever.
My general hunting/hiking boots are the Alpina "Peak" boots and fit absolutely terrific. They are heavy-duty and very supportive. Again, never had a blister in them. Ever. It's gotta be truly cold for me to not grab my Peaks and reach for my Nepal Extremes.
My light-weight boots are new to me - Oboz "Bridger MID", but fit beautifully and seem like great summer/fall-ish trail boots.
What I'm getting at is this: no matter the boot (presuming a true quality boot), fit is everything. Try on a pair at a brick-n-mortar backpacking/climbing store if possible. Most of the climbing geeks trash their boots regularly and become well-acquainted with "boot fitting".
Find the best fitting *quality* boots with the type of sock you will be wearing. Then wear 'em around your house, up and down (interior) stair-wells with a pack on. If they fit, you'll know it. If you get some hot spots, try different lacing methods and if that doesn't work RETURN THEM (just don't wear 'em outside).
Kennetrek's and Meindl's are well regarded in the hunting community and seem like excellent quality boots, but don't limit yourself to just those two choices because all your huntin' buddies wear 'em.
Try on some Asolo's, Alico's, LaSportiva's, Lowa's, Scarpa's, Zamberlan's, etc and see what's the best fit for *your* foot shape (not just length, but width, thickness, natural gait/flex position, etc).
