Adidas taekwondo ballet sneakers BN inbox

Brand new in box, Adidas, taekwondo ballet sneakers. Bought these off of StockX and they will not let me return them. But they are too small for me. These sneakers are so adorable, and sold out at adidas. This is a ladies size 9. They come with white laces or a set of black laces. I usually wear a 9 or 10, But need the 10 in these.
