DuPont polymers contribute to productivity and performance of midsoles, toe puffs, heel counters and other footwear components  

DuPont Surlyn® resins offer a combination of properties ideal for specialty components of shoes, such as toe puffs and heel counters. Shaped by thermoforming or injection molding, parts made of Surlyn® resins give structure and abrasion resistance to these components.

Elvax® EVA resins also find widespread use in shoes, primarily as foamed midsoles. In vinyl-based soling, DuPont Elvaloy® resin modifiers contribute long lasting wear, flexibility and chemical resistance.

DuPont's strength as a global polymer supplier has helped serve the footwear industry as it has moved its component manufacturing and assembly locations to a wide range of worldwide locations.
