I normally wear 8.5-9 but after reading the reviews here, I ordered a 9.5. The boot was still a bit short but the killer was that the thick rubber toe was crushing down into the nail beds of my big toes. (I do have short, round "toddler toes" and am more comfortable with a higher toe box.) I returned these for a size 10 and the toe box seemed higher and tolerable, but the rest of the boot was so loose that my heel lifted an inch with each step. If this was a laced boot vs a zipper, I think my ankle and heel could have been held in place. These are being returned, too. Also, the the top of the boot and the part that comes up the ankle (there is probably a technical term for all that but I don;t know what it is) is thin, stiff and "crispy" as if there is cardboard between the layers. The zipper is small, like something one would find on dress boots not these heavy-duty snow boots. As befitting a small zipper like this, the tab is tiny and hard to grasp. I agree with another reviewer who suggested putting a ring through it for ease in zipping. On the positive side, the rubber traction seems like it would provide good stability in snow and ice and rocky terrain.
