I purchased these shoes over a year ago in a size 8.5 and absolutely loved them.  I saw them on sale and decided to order another pair in the same size since my first pair fit perfectly.  I can barely fit my foot in this pair!!!  I measured them up to my old pair and even the bottom of the boot measures up 1/2 inch smaller than the previous pair.  I'm amazed how the same shoe can differ so much in size...knock off???  something is definitely not right.
