Hi @Enrico Casati,
Can you say something about the lasts you use? Are they typically suited for 'normal feet', or are some lasts more suited for people with narrow feet and other for people with wide feet?
For instance, I wonder what the characteristics are of the ankle boot (I'd call it a chukka ) Artista. On the narrow side, on the wide side; what about the instep?
You don't offer different widths, do you?
