INC Ammiyef black mesh

I so loved these INC shoes and bought them at full price ($99) earlier last year for a New Years gala. On the night off, I realized that they were size 9.5 and not my size, which is 8.5. I can return them and get a store credit, but I prefer to get some cash for them instead. They are new and have not been worn except tried on in the store.
