As suggested, I ordered one full size smaller than I normally wear.  Good thing I did, because they are none too big.  I actually could have gone 1-1/2 sizes larger.<br /><br />I originally saw these boots in the gift shop of MD Anderson Cancer Center and loved them, but they did not have my size.  Since I have some residual peripheral neuropathy from extensive chemotherapy, I was looking for a more comfortable shoe/boot to wear with a substantial heel.  These totally fit the bill for that, and they are super comfortable.  The first day I wore them, I was in them for approximately four hours with no discomfort.  But please be aware that they do run quite small.
