I love these.  I have a pair of their boots too and the quality of both are awesome.  Fit is perfect, im a true 8 and bought an 8.  It may sound weird but i am still in the process of losing baby weight so my calves are a little fat... right now the second set of straps that criss cross are a little tight, this set isn't adjustable. Ran into the same problem when i bought my just below the knee bed stu boots after my second pregnancy.  They fit when i got to my normal size, i know these will too.  So if you are like me and you are losing weight or maybe have bigger calves keep this in mind.  Otherwise they are perfect.
