Well, I just tried on these
boots and my experience is a bit different from everyone else's! I have a very wide foot, and if I can get a shoe wide enough, I wear a 7.5. I also have a wide calf measurement... I ordered these
boots in a size 9M as that was all that was available at the time of my ordering... and I LOVE how roomy and comfortable they fit! However, I agree that they must run short because my toes are almost to the end and that wouldn't normally happen with a size 9. So, for my two cents worth, I say, If you have wide feet and 'ample' calves, this is a great boot style for you!
PS: I also love the soft, pliable leather! No pinching on my tender ankle bones! :)
