Pyer Moss DMX Reebok Sneakers

I literally just bought these but they don’t fit me. I’m Hella sad about it because I never get a chance to like a hypebeast shoe but I love this and can’t find it in a 13 anywhere . I’m willing to sell or trade for this same shoe in my size. It says 12 but 45.5 eu feels more like an 11 1/2 to me.
