These are really sexy HIGH heel pumps.  In my size they are 5 1/2 inches tall.  They are actually not too difficult to walk in, I don't think I'd try to dance in them, though.  I noramlly wear a size 10, but had to order size 11 to get a good fit ( the 10's were too tight in the toe box, even with open toes).  I definitely recommend going a size larger.
