Brand new in box Birkenstock Women's Tess Embossed Sandals Size 39 - equivalent to US size 8/8.5 The Birkenstock Tess is an interpretation of the popular ballet flat in a classic Mary Jane design. The shoe has a feminine look, but still offers exceptionally good stability thanks to its narrow strap with a hook-and-loop fastener across the instep. The upper is made from embossed suede.
