XL vs XXL - Shooter

[Mermaid Russet]

Hello! I"m starting on a silicone tail DIY project and have decided to use a finis shooter in my fluke. The XL ends at size 13 and the XXL starts at 13.5. I'm a size 13, but I want to be able to wear swim socks. Does anyone have any input on which one would fit better? Thank you!

I think go the next size up if you're going to wear socks. If get the size 13, it might be hard to stuff your socked feet into the monofin.
