These boots do look attractive. I probably should have read the reviews more carefully, however. The zipper area inside the boot is very frayed, and I have never had a problem zipping up a boot, previously or since then. I have an average calf, and I can barely zip up and buckle the left boot! I,too, am concerned about the zipper, but I have only worn them once. I, personally, can only put knit leggings inside the boot.

I got the boots at a very good price. I would not pay the price that is posted. I was surprised that MIA was such low quality. If you get them at a good price they may be worth a try. Obviously, not everyone found the boots to be tight in the calf area.
