These Gizeh sandals from Birkenstock are from their Tatami line. They are size 41 or 10-101/2 per their size chart, and ”regular” width which they say is the same as C-D width again on their size chart. The color is Ecru. I believe it is nubuck leather. Very minimal signs of wear. I loved these but don’t tolerate the thong style with my tootsies. Hope you will like them instead.
