LOVE!  I bought these to take on a hiking tour in New Zealand and got them several months early so I could wear them in.  I could have bought them the day before the trip and been perfectly happy.  They are so comfortable!  I have size 10 feet, average width, high arch. I ordered a size 10 and have the perfect amount of wiggle room without sliding around in the boot.  As far as comfort, these are the perfect boots for me.  I haven't had them long enough to weigh in on durability and longevity but would absolutely buy them again for comfort alone.
