I love Vionics, but this was inferior quality, obviously not the same. They failed to offer proper foot support and started to fall apart a couple of months after I got them.  Although they are both stamped "Vionic", After wearing them for 2 months,there was 1/4-1/2" less thickness in various parts of the sole, they were completely flat, no curvature to the sole, loose and frayed fabric on the straps, and the arch support felt like a rock under my foot.
