I was looking for a stylish flip flop that had some arch support, and these Teva thongs provide both style and support.  I wear them almost every day and have owned them for a couple of months, and I was dismayed to notice that the back heel on my left sandal is tearing apart at the edge.  Bummer!  They are so comfortable to wear, so I'm especially sad that I paid good money for a shoe that's already falling apart.
