This is my third pair of Teva thongs.  All are different styles, and I have been very pleased with them all.  The Tirra thong is comfortable and looks nice.  I wear a size 7, and it fits fine.  There does seem to be a little extra room beyond the toe, but that doesn't bother me.  I bought the chocolate chip color, and it is a light gray-khaki, trimmed in brown, a good neutral.  The foot bed is sturdy; this isn't a flimsy flip flop.  My foot molds to the shoe bed.  However, since I have a high arch, I would have liked a bit more support in that area.  I bought them on sale, and for the price I paid, they are wonderful.  At full price, I might have bought an ortho-shoe for the extra arch support.  Still, I am very pleased and do recommend.
