I was  very happy with these boots, at first. But, as others have posted the heels collapsed. I tried Gorilla glue to no avail. They completely lost all support. Now, it took about a year for this to happen, but if you are dropping $200 you expect it to last. I was doing short hikes in the Colorado Rockies, but nothing extreme. I truly feel bad for those that had this happen right out of the gate.
