Love these boots! I bought a size up as recommended for most Frye styles, and they fit perfectly. Super comfortable... first time I wore them was to a concert where I waited in line and stood for 4 hours, then walked a couple of miles, and danced, and walked some more... and my feet were perfectly happy.
The only issue I had is that the shaft of this boot is pretty wide, and it gaped on me a fair bit. I just put an extra hole in each of the straps and did them up tighter. It gave the boot an edgy-er, rock'n roll effect that I really like (they go with True Religion jeans like they were made for each other!).
My next pair of boots will definitely be Frye. The quality, craftmanship, and style are incomparable!
