Knee high boots are supposed to come up to right under the knees, which means the shaft length should be about 15-16 inches from the bottom of the boot.  However, although the description of these boots claims that the shaft length is 15.5 inches from the arch, the shaft length is actually about 14 inches.  These boots was about 1-2 inches below the bottom of my knees.  I do not have exceptionally long legs - I am actually quite short at only 5'2".  Therefore, I consider this false advertising, especially when I get my hopes up high for finding the perfect boot and it turns out to be not as advertised.  In addition, I ordered the medium fit, but it actually fit narrowly.  Plus, I always wear either size 6.5 or 7 in boots and the 7 was a bit tight.  In summary, shaft length is shorter than advertised, fit is smaller than advertised, and sizing is smaller than normal shoe sizes.
