Birkenstock Tatami HARMONY Sage Leather with Mother of Pearl Accents 
SIZE EU 41 US Women's 9.5 - 10 WIDTH is Birkenstock NARROW ******* IF YOU HAVE NEVER WORN BIRKENSTOCK: They state their Narrow width is designed to accommodate an A-B width and their Medium/Narrow width is similar to most Regular widths from other brands

This particular shoe has a pressed cork lining on top of cork [Birkenstock described them as a hidden and flexible cork/latex foot bed].
The sole is Polyurethane [described as shock absorbing soles by Birkenstock].  Each shoe has a metal chain with round Mother of Pearl discs suspended.
The strap by the arch does have an elastic insert for fit [see photo].
The toe separator is leather with a plastic sleeve. New, they sold for $130
The Tatami line of Birkenstock is no longer made.   

I bought these online from an authorized Birkenstock Retailer, but I never wore. 
I am selling as I have collected more Birkenstocks than I'll ever get around to wearing.
 *****THIS SHOE RUNS A BIT SHORTER THAN CLASSIC BIRKENSTOCK***** ******WHEN BIRKENSTOCK MADE THIS TATAMI LINE, THEY HAD AN ALTERNATE SIZE CHART FOR THEM. SO, THE 41 SIZE FOR THIS SHOE WAS LISTED AS A US WOMEN'S 9.5 - 10, WHEREAS THE CLASSIC/USUAL BIRKENSTOCKS LISTS THE 41 AS A WOMEN'S 10 - 10.5. SO, IF YOU ARE A SIZE 10.5 , THIS SHOE MAY BE A BIT SHORT FOR YOU***** I AM A 9.5, AND I USUALLY WEAR 40 REGULARS IN CLASSIC BIRKENSTOCKS. THESE FIT ME FINE,
