Men's Christian Louboutin Arpoador Sneaker - Size 41.5 (8.5)

My husband wore these twice but they are too small for him; he's normally a 42.5. They for more like a 9. Purchased at Holt Renfrew. I have the receipt and can give it to the purchaser. Both dust bags are brand new. The first 2 pictures are stock pics; the rest are of the actual shoes.
