Corkys Oasis Glitters Backless 2 3/4 inch platform wedge on the same foot bed as the Carley without a back strap. These are been a staple piece in my wardrobe this year. I have worn the cognac Oasis almost every day during the summer, black glitter has been my second fave ! I Love the open back. Shoe feels nice and secure even though there is no back strap.
