These fun slides / flats are Materia Prima by Goffredo Fantini.  The tops are leather cut outs with a horsehair feel on the top.  They are a size 36 European, so approximately a size 6 US.  They were made in Italy and have 1" tall heels, are 9-5/8" long from heel to toe along the bottom, and 3-1/4" wide at the widest point of the toes.  Very nice, please view photos.  From smoke free home.
