Another customized option would be to reproduce on the shoes any particular decoration which recalls any symbol or drawing which may has a personal meaning for the customer. This would be a proper mark to make your shoes unique.
The design of any model could be modified to customer’s liking. Decorative patterns (brogues) could be changed according to someone’s preference and different finishes ( classic, antique or streaky nuances finish) could be chosen.
On top of bespoke services applying letter initials has always been a must, especially on tailored shirts. This could be done on shoes as well with “tattoo” drawing or with embroidery and also a special gold or silver pin could be applied.
