THESE "JACKS" ARE COMFORTABLE, FLASHY AND WAITING FOR SUMMER.I ORDERED THESE IN SILVER, BUT ALSO HAVE THEM IN BLACK AND DARK BROWN BLACK LABEL.  THERE IS NO ARCH SUPPORT, BUT ANYONE WHO WEARS JACKS KNOWS THAT AND ACCEPTS IT, I WEAR A 12 M AND THE 12M IS RIGHT ON THE MARK.  NO HEEL OR TOE HANGOVER . I LOVE THE COLOR AND MATERIAL SELECTION AND WILL KEEP COLLECTING JACKS. I ALSO WEAR BERNARDO AND THINK JULIA (WHICH IS A TOTALLY DIFFERENT TYPE SANDAL)
