Vince Camuto manufactures a beautiful and well constructed product.  I wear a size 6 1/2 to 7 boot.  My calf measures about 15 inches and is muscular.  These boots are advertised to have a opening of 15 inches which should fit snugly. I tried these boots on at a high end dept. store.  They were the last pair and a 7 1/2.  I figured I would wear thick sox and all would be good.  The boot opening was more like 13 inches......I measured with a Lufkin Tape Measure.  It's obvious you have to have slim legs to wear this product.  I gave a 5 because of the quality but inaccurate advertising is is insupportable and a time waster for the customer.
