Envalior's Arnitel Powers Next-Gen Norda Trail Running Shoe

The company's advanced polymer technology delivers 30% energy return boost in new 001A footwear application.


Envalior's high-performance #Arnitelpolymer technology will power Norda's next-generation trail running shoe, the 001A. The specialized thermoplastic material delivers performance advantages in the midsole, highlighting how advanced polymer science is revolutionizing athletic #footwear.


Envalior noted its proprietary Arnitel Performance blend achieves a 70.8% resilience rate in the 001A midsole boosting energy return by 30% compared to the previous Vibram SLE midsole. The material also enables weight reduction of 7% to 10% for the overall shoe, with the midsole itself 15% lighter while maintaining durability.


Arnitel Performance outperforms other midsole foam materials in rebound weighted by foam density," explained Andre Oosterlaken, product and market innovation manager for Arnitel at Envalior. "It exhibits extremely low energy loss after foaming, enhancing wear performance while ensuring reliable foot support during intense physical activities.


Increased rebound

The company noted the material demonstrates 17% higher rebound compared to #TPU alternatives while maintaining stable mechanical properties across temperature ranges a factor for trail running applications. Equally important for today's performance materials market, Arnitel-based #midsoles can be recycled and are available in low-carbon-footprint and bio-based grades.


Moreover, the company noted the 001A represents a comprehensive materials showcase, combining Envalior's Arnitel Performance midsole with a proprietary #biobasedDyneema and #recyclednylon weave upper that weighs under 90g/m² yet delivers over 3000 N tear strength. The shoe's foundation features a Vibram soleplate with Litebase and Megagrip technology.

"Partnering with Envalior to integrate Arnitel Performance into the 001A midsole allowed us to significantly increase rebound and reduce weight without sacrificing durability," said Nick Martire, co-founder and CEO of Norda.


The material technology has earned a reputation for balancing durability and comfort in sports shoes, offering a soft touch with lightweight structure and rubber-like strength and flexibility. #Envalior's Arnitel Performance ensures the midsoles maintain reliable performance for over 1,000 kilometers of use.

The #Norda 001A featuring Envalior's Arnitel Performance technology will be available to consumers in fall 2025.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
