I have several pair of cowboy boots, all 9 1/2 EE.  Some that I have ordered on line.  These looked more narrow than the 9 1/2 EE that I usually wear; then, when I purt them on I was right.  I wore them to dinner anyway (about 90 minutes) but on the drive home all I could think of of was "hurry up and get home so I can get these things OFF". I held these up to the pair that I am wearing right now and the sole of this Justin boot is about 3/8 inch more narrow.

I love the look of the leather, I just can't wear them.
