These are very cute boots and fit my feet well. The problem is that my calves are 15-1/2 inches. That should mean that the boots fit my calves with the expansion zipper opened. They do not, however. I purchased another pair of boots, and those fit around my calf, so I know it is not my measurements. Just be aware that these will only fit a 14-1/2 to 15 inch calf even with the expansion zipper opened.These are the most comfortable and prettiest boots I've ever owned! Hey lots of complimentsI loves the design on it.
