I presume they will take them in and send them to a local repair-shop (at least that what they do in London). No guaranty that the repairman will use original components. Check with the store. The majority of Italian shoes (Gucci, Prada and Berluti included) use Blake-stitched as the method of choice. If the shoe has a row of stitching (inside the shoe) running around the insole, they are Blake.
