I have these in Olive Suede and Black.  Love both of them.  Super comfortable!  About sizing, I am always a 9M in every shoe, so that is what I ordered.  I liked that they felt a little snug with tights at first because they are real leather and will stretch.  They are perfect now after wearing a few times.  Who wants a boot that flops around on your foot?  However, if you will be wearing thick wool socks for very cold weather, you will have to go up most likely half a size and wide.
