This is a brand new pair of Betula sandals (licensed by Birkenstock).  They still have tags on and are in their original box.  A beige/tan coloring with a buckle on the side.  The footbed liner is cow suede and the footbed is cork.  This is the same contoured, natural cork and latex footbed design that are in the traditional Birkenstock line.  The only difference is that these have a synthetic upper.
