I love these slippers, however, I am an 8 1/2.  I bought these in an 8 and a 9.  The 8 was WAY too small and rubbed my heel when I tried it on, so I returned them.  I tried on the 9 and my foot slipped badly in them.  So I had to return these as well.  I wish UGG would make these in half sizes as they do the boots now.  I really want these slippers but their sizing doesn't work for me.  Very quality product, just missing my size.
