All of Danner's boots used to be made in USA. Sadly, they've recently started importing from China. I have a seven year old pair of Danner mountaineering boots; Vibram soles, steel shank, Gore-tex and Thinsulate. They're my sole footwear when I'm in the mountains of northwest Montana. Not sure what I'll do when they wear out -- some day.
There wasn't any definitive information on the Danner website with regard to where all their boots are built. I know the headquarters is still in Portland, Oregon (also the home of Langlitz Leathers...very cool) but that doesn't speak to whether they outsource. If anything, I might guess that the lower-tier models might come from elsewhere.
At the same time, we have to be willing to pay for quality if that is what we desire. It is just taking me quite a bit of courage to pony-up the big bucks for the excellent boots I pictured above. White's Boots offers a great explanation about support, but I'm wondering if that heel just looks a bit bizarre.
