Thermoplastic Polyurethane Film (TPU film)

TPU film is an abrasion resistance technology used for certain Diadora Utility work shoes. The certification indicates that a work shoe features a thermoplastic polyurethane film. This is a transparent layer of hard plastic and silicone material that completely encases the EVA and PU insole. Thanks to this technology, the work shoe has excellent abrasion resistance, making the footwear last a lot longer.
