These Upaco patented films have been developed to bond to various sole and midsole materials for permanently attaching sole. Depending on the different substrates that need to be bonded, the films may be used in-mould or post-mould.
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 by the structure of competition tyres: 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 focalising only on the weight of the wedge and upper shoe parts? The outsole can also be helpful.
