In my experience I would go with the 11.5 but that is entirely based off of the way my toes fit in the shoe. my pinky and ring toe are right up to the edge. This would be fine if the material were soft like a tennis shoe, but the leather is firm and rugged so I wish it had more room. Remember your feet expand as they get hot throughout the day and you can always add a thin sole insert to take up a little space, but if you go to small you can't really make more space. My brannock size is in between 10.5 and 11 with a D width. These shoes run kinda narrow. I wish I would have went with 10.5. Still love the boot though.
