These Upaco patented films have been developed to bond to various soling and midsole materials for permanent sole attaching. Depending on the different substrates that needs to be bonded, the films may be used in-mold or post mold.
Frasson s.p.a. and Rubbermac have been the first European users of this revolutionary bonding system.
The new Rubbermac multiple compound concept is inspired from the structure of competition tire: each rubber compound is dedicated to the specific need of the customer.
In the same way, the rubber outsole is also composed of specific compounds that allow different performance, depending on the area of the outsole.
This structural technology is specifically developed to reduce the weight of the final shoe.
So why focalizing only on the weight of the wedge and upper shoe parts? The outsole can also be helpful.
