Women's pink/purple shoes. Size 43. Ballet flats.

Women's pink/purple ballet flats. Size 43 EU,12 US. I ordered these online and didn't realize they were the wrong size until it was too late to return them. I tried to wear them once. I have long,narrow feet and can only wear shoes with structured sides, or I walk right out of them! They are a pretty sort of pinky lavender hue that the photos don't really convey.
