Vionic Pewter Sandals with Adjustable Straps

Vionic Della T Strap Wedge Sandals Size 5 Color is Pewter Sandals have a T-strap with Bow detail Wedge is 2" These are brand new, but I see my mom placed a support in the upper arch area, see last picture. She is typically a Size 4.5 so these may have been too large, and she tried adding support under the top, but never worn them. Has side expansion straps that give with each step.
