These Bob's were a little bigger than excpected as I ordered an 11 which I had done for previous styles.  If you order the ones with open back as these are they run true to size.  All is not lost though, I will wear these around the house and re-ordered the same style in a size smaller to wear out.  Would use this seller again.  I also purchased the same style in black and a size smaller at 10.  They fit perfectly and I can not say how much I LOVE MY BOB&#34;S.  I now have 5 pairs in varying styles and colors.  They are so comfortable its like wearing your slippers outside.
