I tried them on in a shop recently as I was looking for some light, summer hillwalking boots. I found them to fit quite small, so I needed a full size bigger than my shoe size, despite wearing just one pair of thin socks. They are quite narrow, but not exceptionally so. The sole is fairly bendy both front-back and side-side, but it looks deep and gripping.
The thing that worried me most was that the insole seems to be glued or otherwise fixed in place. Not good if you like to replace them with something sturdier (the Elios insole is very soft and comfortable, but not supportive).
In the end, I decided that the Keen Targhee were a better bet - slightly more comfortable with possibly a slightly less aggressive sole, but a whole lot better insole. Though they do look quite ugly. I haven't bought either yet as I want to try some more before deciding. Why can't someone make a light summer boot in black rather than all these horrible multicolour eyesores!
YMMV.
