The Sava flip flops look great and are comfy, but if you're buying them because they are advertised as having a memory foam footbed then be warned. If like the rest of the world you expect your memory foam to have viscoelastic properties that slowly form to the shape of your foot then you will be disappointed. This memory foam is just like normal foam - purely elastic with no shape-hugging properties. Whether it's dodgy marketing spin (as I think it is) or some new wonder material that no one else is using, treat these flip flops like any other comfy and good looking shoe.
