Am a solid 9M in closed shoes so initially ordered size 9M in Cognac Nubuck color but boot seems to run 1/2 size small - was tight across top of foot and along sides. Reordered in size 9.5M, also in Cognac Nubuck. When the boots arrived they were size 9.5M but NOT the color I ordered. They were a darker brown color (different name). I basically like the boot and think it's very well made and will keep it despite being sent another color. I'm too tired with it all to return it again at this point.
