There's so many options, and weather you want leather, synthetic, lightweight, or heavy duty, there's something that will fit your feet and needs. I have backpacking boots that are a synthetic outer w/ some nubuk leather, and they are Gore-Tex Asolo's. It's not what I wanted, but they fit me better than anything else, and they are so light I use less engergy on the trail.
Heavy leather boots are more durable, will last longer, and offer more support. If woods bumming, easy camping, or even backpacking with less gear, I'd prefer stiff leather.
Asolo, Lowa, Scarpa, and even Merrell make some higher end all leather boots. I had a pair of Italian made Merrells for over a decade. The soles dried up and fell off, so I got the Asolos.
Redwings, I had a pair of their work boots, used them for over 5 years. Irish Setters, Carolina Boot, Danner, are also good, and look at sites like US Calvary for modern versions of military boots, lots of choices in materials and colors.
