I did not specify the EU sizing, Mr. Kuti did, I said I was UK6.5 and I received EU41.5.
I returned that pair both because of size and wrongly executed design caused by misunderstandings between two non native English speakers - Mr. Kuti and myself.
Right now I've got a pair of EU40.5 at my place and even if I'd like to, I can't say they fit myself the way I'd like them to.
I have posted earlier about them likely being the correct size for myself, especially when worn with my ortophedic insoles (low instep), but I don't believe in it anymore.
I have put them on for whole an hour so the leather could take the temperatuer of my feet and mold around them and I end up experiencing too much heel slipage and my toes don't reach into the toe box far enough.
Fiddler and others said they were UK6.5 and have gone EU40 in Vass F and were fine.
I took and measured the traces of my feet over and over again, have gone to a department store that offers C&J and tried on several pairs for countless times (some I like in UK6 others in UK6.5), as well as I have gone to three cobblers to have them have a look at the Vass.
They agree the current size is too large but are afraid of telling me how much to size down.
Also I have a pair of US7 Rancourt & Co Ranger Mocs which I am very comfortable in, yet of course I do understand it is difficult to compare a suede mocassasin derby to a calf dress oxford.
So now I am faced with the tough decission whether I should size down to 39.5 or 40.
40 definitely won't be too small but might even still be on the large side, especially as one of my feet is noticeably smaller than the other anyways.
If I go 39.5 I might end up with a pair that is too small for my bigger foot, but if I am lucky they might just be the best fit I could get out of the F last with no more than ~1.5cm in additional length.
Have a look at the link below.
My bigger foot is ~253mm long, according to the link I should always be UK6 and either the greatest length in 39.5 or the smallst in 40, not taking width, heel etc. into account.
No idea if Vass sticks to this very values though.
Agree with Louis XIV size chart from Wiki - gives you a true indicator if your familiar with converting from UK (amber) size to Eu (red) size.
