I have worn Danner GTX EMS boots and they always fit like a glove. Thought I would get a quarter boot for the short shift so I ordered these. If I hadn't been accustomed to the quality of Danner I may have thought not much about these, but they fit like the cruel shoes Steve Martin joked about in the 70's. THe width isn't near as wide as the other boots, and caused my feet to cramp. Wore them for a solid 3 weeks thinking they would break in...they don't. No arch support whatsoever.
If you love your Danners, do not buy these!
