1. Very comfortable. I tried on a similar pair in store with the Grand OS tech and it is top notch. Minimal break in period required, if at all.
2. Sizing is as expected. I usually wear 10.5 or 11 depending on the type of shoe and brand and these Cole Haan's in 11 fit great for me. I would suggest per my own experience and as other reviewers have said to go at least a half size bigger to get the right fit. I also have slightly above average width and the medium D fit fine (albeit sizing up a half size probably helps).
3. The colour is slightly darker than in the pictures but still very nice. What you can't see in the pictures very well, however, is that the toe is a significantly darker, contrasting tone than the rest of the shoe. It was not what I expected BUT it has grown on me the more I wear it and it does add a little fancier detailing.
Overall, it's a classy, high quality show that I would recommend to others.
