GUC Blowfish Slip on Canvas Sneakers

Gray with cute butterfly inside Some scuffmarks around the bottom Slip on These are a little big on me and I wear a 9. So they’re either a 91/2 or 10. I can’t find size anywhere. Online it says that you can find the size down inside the toe part of the shoe, but I’ve looked all over and can’t find it. I’m going to keep the price low, since I can’t say for sure what size they are.
