NWOT Danskin Navy Ballet Flats

I love these Danskin shoes, but due to a bad ankle fracture, I still can't wear flats. I tried walking in them in the house, but my ankle needs more support. They have never been worn outdoors and are in perfect condition. The size says 5.5, but they fit my size 6, B width foot perfectly. Please see the length measurement in the final photo.
