To begin with, good boots for the mountains will be very close to more than your ceiling. I like mountaineering style boots, though have used a few pairs of USA made Danners that worked out.
My favorites are Lathrop and Sons Mountain Hunter and Hanwag Alaskan GTX:

Mine are non-insulated, as I use good wool blend socks for warmth and have always found these adequate. I have hunting friends who also like Kennetrek and similar brands.
