Midsoles for athletic sport shoes

Arnitel® Foaming grades for midsoles provide high rebound, consistent performance, are longer lasting and offer attractive sustainability characteristics. 

Enhanced Performance, Reduced Footprint

The footwear industry is rapidly evolving, driven by the increasing demand for enhanced performance, cutting-edge designs and improved sustainability. Consumers and athletes alike are pushing for products that offer durability, superior performance & eco-friendliness. To stay ahead of the curve, brands and OEMs must adopt innovative, upcoming process technologies that merge sustainability with design flexibility and high-performance standards. The pressure to innovate has never been greater—those who fail to adapt risk being left behind.

Chasing the ultimate material for midsoles

As the industry shifts toward cleaner options, traditional materials like EVA are being reconsidered. There is a growing emphasis on recyclable, bio-based, and low VOC materials that align with both environmental and performance goals. Leading footwear brands are now experimenting with advanced thermoplastics and physical foaming technologies to deliver midsoles that meet the demands of both sustainability and high performance. However, finding a material that offers the ideal balance between these benefits remains a challenge, as current options often come with compromises.

Engineered for Performance: Arnitel® TPE-E

Envalior’s Arnitel® is a high-performance TPE-E used by leading athletic footwear brands. Unlike traditional EVA midsoles, Arnitel® offers processability in physical foaming processes, delivering midsoles that enhance both speed and endurance. As athletes demand more durable and sustainable materials, Arnitel® is driving the industry forward with unmatched performance. It not only meets, but exceeds, the needs of both athletes and manufacturers, offering a range of key benefits:
