Prada Point Monolith Loafer 39 black

Prada Pointed Black Monolith Loafer. These shoes are in really good condition. I just bought them secondhand and unfortunately they are too big for me. Now it’s listed as a size 39 which would be an 8 1/2 but these would be better suited for a 9 or 9.5 I typically wear a 8.5, in other Prada shoes I have I wear a 7.5. I was told these b would fit tighter, they do not. Again a 9 or 9.5 would be best!
