I ordered my normal size and they were a bit too tight (right foot).  I ordered a half size larger and they fit so comfortably.  If you desire to wear thicker socks, then I do recommend a half size larger.  They look better than I expected, and with some black polish and a good buffing they are beautiful indeed.  They really look good with jeans in black, but look great with exercise clothes in white.  I may buy a second pair in the future.
