I wear a size 9 regular shoe but when buying tall boots, need the wide shaft.  I really liked the look of this boot on websites and ordered the wide shaft in a size 9.  The product itself wasn't quite as rich in color once I received it vs. how it appears on the website.  And although the wide shaft worked for me, the foot portion of the boot was way too small.  For me, it was at least a half size too small.  I have re-ordered the product in a size 10, as the 9.5 was not available.
