As you already know, "fit is it" with boots, so quality brands i'm familiar with are Alpina (hiking and mountaineering boots), Asolo, LaSportiva, Lowa, Scarpa, Trezeta and Zamberlan.
Honestly, if you're putting 6 miles a day on your boots, everyday, you're going to be have to find a brand that you can re-sole otherwise you'll be breaking in new boot leather.
Have you considered a pair of Limmer Custom(or even their "off the rack") boots? The Norwegian welt style sole is more economically replaced than other soles and will generally wear longer.... The next pair of boots i'm buying are going to be a pair of Limmer's. I've heard of too many ecstatic Customers (very active hikers/climbers) who've used their boots hard for many years and just re-sole when it's time.
Just google "limmercustomboot".
