I was truly thrilled to find a cute pair of flip flops, but with the added comfort.  I wear flip flops all the time and find I am becoming flat footed.  Vionic adds a great support for your insole, but not too much that they hurt like Birkenstocks do when first wearing them.  They are sturdy and so comfortable.  Definitely worth every penny and will last longer than the several dozen flip flops I have to purchase year round.
