Hey Ron! I sized down 1/2 sz. I rock 9.5 in Nike but sz 9 in my dress shoes. The lunar sole makes them very comfortable for work. I'd take your favorite and most comfortable pair of Cole Haans and go with that size I guess.
The Cole Haan x Nike LunarGrand are a NYC SoHo exclusive. I believe they accept phone orders though. I'm on my feet all day and easily the most comfortable dress shoe I own. I don't get to wear sneakers at work so I guess this is the alternative..haha
