I bought these specifically for a hiking trip. I only had two days to break them in by wearing to work a desk job. They were quite comfortable from day one but I was nervous about getting blisters. After a 7 hour hike on Mt. Washington I did not end up with a single blister.The ankle support saved me a couple of times too. They also have great traction. There were some slippery rocks but these boots handled them like a dream. I couldn't be happier about this purchase. I ordered the same size I wear in athletic sneakers and I had no problem with the fit. I've never had to buy a wide fit, and these felt slightly narrow to me, but not uncomfortable at all. they just hug my foot a little more than my other shoes. Bottom line is that I love these and will be wearing them for all my future hikes. Some people complained that they were not waterproof as advertised. I hiked through a few shallow streams and had perfectly dry feet. If you're traveling through something deeper the water will likely get through the breathable mesh. I don't think they'd do well in snow either, but I haven't tested that theory yet.
