Manidipa, Sorry if I was not clear. The thong style is the Birkenstock Gizeh and the two-strap one is the Dr. Scholls that I buy from the Bata stores in India. I also had a Dr. Scholls thong style sandal that is very similar to the Gizeh. I wore them out and had to discard them so I can't take a pic, but they look like this one:

The straps were leather and the underside was lined in soft suede. The footbed is identical to the two-strap style (so slippery) but the thong helps them stay on. I love this style of art too and am always on the lookout for art to buy but have never found anything that sings to me yet. If you have any recos, please let me know.
Freckles, I have the Mayari in a purple/grape patent and the Gizeh in a golden brown. I had the Salina in a burnished leather style called Amalfi, The vibrant colors use a synthetic material for straps called Birko-flor and are less expensive. The leather styles are harder to find, but there is a gorgeous red burgundy that takes on a lovey hue as it ages.

Take a look see on the Naot webpage. Different collections are cut differently and there are several that fit medium feet very well. I take a wide width in regular shoes and the Birkenstocks R width fit well. The default width for the womens' line is the N,
