I own several pairs of Clarks in 9WW (they all run narrow).  Unfortunately, these were too tight across the top of the foot, so I had to return them.  A larger size would not have helped because the length was perfect.  I was very disappointed because they are cute shoes with the exact heel height I wanted.  Also, they are Clarks, so they would have been comfortable if they had fit properly.  Beware if you have wide feet, these may not fit you.  If you do not have wide feet, I highly recommend these shoes.
