OP, if you haven't made your purchase yet, I would recommend you check out Zamberlan boots in addition to the others on your list.
Many years ago I became disillusioned with a couple of "name brand" boot makers that sold on their name and perceived quality but had moved production to Asia. The problem was that the quality just was not there anymore and the boots didn't hold up or just had inferior workmanship.
I ended up looking at some Zamberlan, Scarpa and Lowa boots. The all make great quality boots but, for me, the Lowa boots were too roomy, the Scarpa boots were too tight and the Zamberlan boots were… just right.
I bought them during the summer and immediately took them on a quick 5 mile hike the day I got them. I use a liner and a sock and I did not have a single hot spot or any pinching so no break in was needed for me. I was able to use them on a backpacking hike soon after with no issues.
How a particular boot fits a foot is unique to each individual. Fit wise for me, these boots have an excellent heel cup with zero movement, a roomy enough toe box so there's no cramping and good arch support and ankle support. The construction and materials used is top notch.
I've used my Zamberlans for hunting, hiking, backpacking and summiting various 14ers across Colorado. I've never had an issue and the waterproofing works in snow and mountain stream crossings. The terrain I've traversed has been steep and rugged in many places and I feel very confident with these boots. The soles are aggressive and "grippy" on rugged terrain.
I especially like the amount of ankle support they give me whether it's on steep ascents or descents, across scree fields or wet boulder fields, or just good 'ole slippery mud. If I need to edge the boot to maintain grip and position, that support is tremendously helpful in stabilizing me and my backpack load. With an additional 60 to 80 pounds of quartered elk meat on the back, that support becomes invaluable.
Overall, the fine Italian craftsmanship is evident from day one to even after many years of rugged use. They still look good, perform great and can be resoled whenever needed. I recommend these boots without reservation to anyone who asks.
