"First off, these are some great boots. I bought them A month ago and did a very little amount of break in. Some city walking and 2 1.5 hour hikes. Nothing too strenous.
I've just returned from Yosemite, I did the Halfdome roundtrip day hike in 12 hours and I am very happy with these boots. I've never done any long distance hiking before and I had almost no trouble with the boots. The only problem was a hotspot on my left little toe, but that was due more to the fact that I almost broke it 2 months ago and it is still not back up to top shape.
Great boots, I highly recommend them."
