These are the most comfy boots! I ordered both black and brown.  Size 9, I am either 8.5 or 9 and in reading reviews went with a 9.  They are more narrow than the ther shoes I tend to wear, but I honestly feel like they were custom made for my feet, and they are immediatley comfortable, no "breaking them in" required.
I got them for a great deal right before Christmas, and planned to return one pair after seeing their colors, but now I have to keep both, they seem very well constructed so I am justifying my splurge by telling myself they will last for YEARS.  A friend who describes herself and "thick calved" tried them on and could not zip them up.  But I have no issues.
