The reviews said that the boot would be an exact fit. I ordered an 8.5 normal size and I can wear the boots without sock and its somewhat ok, but with socks on it WAY TOO SMALL.  As for the comfort part of the boot that everyone is raving about on the reviews I am not so sure.  The shaft of the boot is incredibly soft and if that is what the are referring to as far as comfort then I will agree.  However the padding in the sole of the boot is somewhat lacking.  If you plan on doing any sort of walking for more than an hour these could cause some pain.  I do love the boot, unfortunately I'm returning mine because the size problem and they don't have the next size larger available.
