Try a bunch side by side and get the ones that fit the best.
I just went through a search for a new pair of insulated boots. I ordered Zamberlan Sawtooth, Kenetrek Guide, Crispi Hunter GTX and some Lowa's that I tried side by side. The Zamberlan's felt pretty good, the Kenetrek's felt great but when I walked they rubbed my heels, the Lowa's were tight and the Crispi's fit better than my old Asolo's. The Zamberlans were good, but side by side the Crispi's were a little better. The Crispi's are the first boots I've ever owned that had zero break-in time.
