I wear other Vionic Orthaheel shoes without any issues and love them a great deal.  These seemed to have the same support but just were not the right fit for my foot.  When I slipped them on the shoe would turn slightly and I'd find myself standing on the edge of the heal rather than the middle.  Other Vionic Orthaheel (Relax Slipper and Cairns Clogs) have been wonderful for my feet... this particular one just wasn't right for my foot.
