Bought the 600's for a hiking trip overseas later this year, but wanted to make sure I broke them in early. The good news is that I probably won't need to do much to break these in, they fit like a nice pair of basketball shoes right out of the box. I read reviews beforehand and went with a size 1/2 smaller than normal, and as expected a 10 1/2 fits like my normal 11's. They're stylish, light, and are by far some of the most comfortable boots I have. I look forward to putting some miles on them. The bad news is that the tongue section that attaches to the side ends at the base of the rise, so unless you keep to walking in puddles I doubt the boots will be as waterproof as regular Danners, which usually stay attached all the way to the top of the rise. They also do a good job of hiding the fact that these boots aren't actually made by hand or in Portland, OR, but instead in Vietnam. Kind of defeats the purpose of wanting to buy a good pair of Danners if you find out after the fact that they probably were made in the same Vietnamese factory as a pair of regular basketball shoes. Explains why they're so much less expensive than most of their other boots. Finally, (and this isn't any fault of Danner), but the pair shipped to me had obviously been returned by another buyer on Amazon. The inside and outside of both boots, as well as the laces and inside of the box, was covered in animal hair. Not just a few hairs, but a gross amount of hair. And the sole was dirty. My wife made me clean my brand new boots outside before I could wear them. Not cool quality control person at Amazon... Not cool.
