It is a typical construction method used by Zecchino d'Oro on sports or casual articles. The precision of the so called “cassette workmanship”, makes a simple rubber bottom a real gem of quality and elegance. Shortly, once you remove the last form inside the shoe, the bottom is meticulously sewn directly on the upper sole.
It is obtained by pasting the rubber bottom to the bottom of the last. This is the process quicker and easier to accomplish in all the work carried out by Zecchino d'Oro.
