I have broken these boots in and hiked around 50 miles in them chasing chukar in the rugged mountains of Nevada. I can say Lowa makes an excellent boot. Great support and very comfortable. Other backpacking boots caused me grief with blisters during the break-in period, but these haven't. I had a pair of kenetek boots and liked them until the waterproof membrane broke down after only 2 year. Didn't want to go through the process of finding a new boot that works for what I need, but can't go with a boot (kenetrek) that is not really waterproof. So glad I did.
