text: I wear 6-6.5 women's street shoe size and the size 7 Sansha fit me perfectly.  I did order the Narrow width because I read that they are wider than expected (I wear regular width shoes regularly).  The elastics came attached from one end.  In one of the shoes, the very front (where the toes are) of the fabric insole lifts a little and bunches when I move my toes (I guess it was not sewed at the very end) but it is not uncomfortable, just inconvenient; the other shoe is fine.  See the Sansha website for correct sizing.
