When reading the reviews, I noticed that sizing seemed to be a issue.  I am 150 lbs. and 5'8".  I am not thin and do not have thin calves.  I have a slightly wide foot. I followed the advice of several of the people who wrote comments and instead of ordering a 8.5 which I normally wear, I ordered the size 9.  When the boots arrived I put them on immediately.  At first I thought that they were stiff and small, very narrow, just as had been described.  Then I realized that there was some paper in the foot bed to help the boot keep its shape.  I took that out and then thought the shoe was too big.  After putting on thin socks (not trouser socks) the boot fit fine.  Also after wearing them for a day, I realized that I need to get some cushioning for the ball of my foot.  These are pretty hard, but then again I have a job where I stand a lot while still needing to look professional.  Glad I have the room to add the cushion.  The boot seems to fit like a shoe that needs a little breaking in and, it being leather, it will do that nicely.  The boot is high quality.  Very attractive.  I hope this helps.
