My wife and I both have these boots and love them.
These boots are very comfortable and require little to no break-in period. I consider them a summer Alpine boot that is lightweight and I have never got a single blister while wearing them.
They are stiff enough for crampon use but I have also used them for hikers while carrying a heavy pack. These boots have performed regardless of the task. They are not insulated so they would not be the boot of choice for high elevations or extreme cold.
