Olive green Birkenstock limited color

Im so upset i got the wrong size in these! These are such a cute style and the olive green was limited. I saw them in the men’s category on line and made a mistake in translating them to women’s, but they don’t go down as low as I needed anyway! If you wear a ladies 9.5 US, 40 Euro, or 7.5 men’s US, these will fit you perfectly if that’s what you wear in Birkenstocks! They have never been worn except to try them on. I just waited to long to exchange. I don’t have the box but I have a different Birkenstock box I can use to ship
