These boots are the bomb diggity ... My calf is not  what one would consider really small.  Needless to say I was very worried they would not fit my calf.  They do...thank you...thank you...Thank You...  I purchased 1/2 size larger in order to get a slightly larger calf size.  Size 9.5  13 calf.  The shoe portion of the boot is a little big..but not tooo much and 5hey are comfortable.  The ankle fits just right so my feet do not slide.  How hard is it to find a Navy Riding Boot?  How hard is it to find a Navy anything?  Well I feel lucky and not only ar3 they Navy, They are well made soft leather, softer sued3vand ultimately soft insole.  I will wear these until they literally fall apart.  One draw back they are about 1 1/2  shorter than most  boots, not meeting the knee.  But who throws away a Bentley because it need shining? The shortness can be remedied with navy tights, longer dresses, and of course who cares when wearing with pants or m6 favorite jeans?
