Love these.  I usually cannot wear thong type sandals as they irritate the area between my first and second toe.  These, however, have been great and only require a couple days to break in.  The cloth straps are very comfortable and the textured foot bed provides nice grip for your foot.  They're kind of expensive for flip-flops but have been totally worth it so far.  I definitely recommend trying them if you have had trouble finding thong-type sandals that were comfortable.
