How does your pair fit? i think you mentioned you have another pair coming?
Yup, I do. Another Arca monk (though it looks like the Jouvet, just without the medallion, Im not sure - either way, its the 001 last). Im a true 9.5D US, and these are a size 10. Very slightly roomy, but I think a 9.5 would be too tight.
tldr, either get your actual US size, or 1/2 size up
