I purchased the blue color and it's very nice-  sort of a brighter navy color but not light blue or cobalt.  I'm usually an 8.5/9.0 size and I decided to go with the 9.  As far as the length of the boot, I probably could have gone for the 8.5 as it's a tad long but not noticeable.  The 9  will give me extra room for a sock and if necessary I can always add an insert IF they stretch out too much.  There is a very nice memory type foam insert in this boot.  Very comfy.  The only reason I gave it 4 stars is that the leather across the top of the foot is a bit snug though not uncomfortable at all and if you have average medium width feet then I would not be concerned about that.  The boot is not narrow or constricting.  The shank of the boot is very buttery soft and thin which is very nice under lighter slacks or during warmer weather.
The heel is stacked  and the sole is a nice rubber like material to help prevent slippage.  I may get another pair in a different color.
Keep in mind that boots like these are meant to be worn with a bit of heel room.  In other words, my heel is not touching the back of boot at all.  Sort of like wearing Dansko clogs where your heel moves freely up and down and I prefer that kind of fit..  But, if you want a super glove like fit, then order your usual size and stretch them out a bit with a thin sock.
