I just picked these up last week. So far I am impressed. They are super comfortable out of the box. I typically wear a 11.5 US in Salomons and Montrails. I went with a 45 in these and they fit great. They give me the room that is need for swelling if I am going to be hiking or trekking to the nearest climb. I look forward to write more once I have had them for a few months.
