Sizing is difficult, I know SQ wears a size 7 in Lanvin (which I don't think is even based on any origins like EU, UK, US, etc.... that is why I always ask on the size printed on the shoe and box just o be sure) but iirc he also wears a size 41 in MMM while I wear a 42. I also wear size 7 in Lanvins and size 42 in MMM. SQ's sizing is strange to me because MMM in size 42 fits me more snug than size 7 Lanvins. If you are size 41 in MMM Lanvin 7 might have some room at the end. edit: i want those espadrilles. i went to the prada store in chi a couple of weeks ago, and the sa told me they are not in production... lies!
