These flip flops are very comfortable to wear and the wedge height is just right.  The thong part is made of a medium weight ribbon like material.  It isn't rubbery or stiff like most flip flops.  But the square "mush" logo at the heel makes an audible sound when you walk and the shoe flips up and hits your heel.  This can be awkward in quiet settings. I still think they were a good buy, but I wish that they didn't make noises.
