I understand your points. Looking forward to the pictures.
Personally, I'm not a fan of the RTW shoes in questions as I don't see the value in paying that much for Blake stitch. Makers like gravati and sutor already fill that niche quite well for a lot less.
Were you fitted in person? Not sure if bestetti even does online bespoke ala kielman, but just curious. What about test shoes?
Wasn't implying the leather isn't inferior, just that using that as the only parameter isn't the best idea in general
