I cannot believe others said these run small.  I ordered a 6 (my usual) and  6.5 in case they were too small.  The 6 are too big!  I have a D width foot and they do not hug my foot and  area bit long.  I need a 5.5, but not available.  I double checked size on shoe to make sure it was size that box said.  Now I need to return to pair.  sigh
