Borealis introduces renewables-based polymer grade for footwear midsoles

• Borealis launches renewables-based ethylene vinyl acetate (EVA) solution developed specifically for footwear midsole applications
• The new grade is part of Borealis’ Bornewables™ portfolio of premium solutions made from renewable feedstocks, delivering virgin-quality performance while reducing reliance on fossil-based materials
• The innovation is another example of how Borealis enables its customers to shift to circular solutions without compromising quality

Borealis has introduced a renewables-based ethylene vinyl acetate (EVA) grade designed for shoewear midsoles. EVA is a lightweight, foam-like material that provides comfort, cushioning and firmness, making it ideal for midsole applications. Part of the Bornewables™ portfolio, the new grade delivers the quality and durability required by the footwear industry—while enabling a midsole with a 45% lower carbon footprint than one based on traditional fossil-based materials. This innovative midsole solution is a clear example of how advanced material solutions can enable the shift to a circular economy without compromising quality.

The Bornewables is Borealis’ range of premium solutions that deliver the same material performance as fossil-based equivalents, but with significantly lower environmental impact. Feedstock is sourced entirely from waste and residue streams, including vegetable oil production residues, waste oils, and by-products from the timber and food industries. The entire portfolio is ISCC PLUS (International Sustainability & Carbon Certification) certified, ensuring full traceability from point of origin through the entire supply chain.

The first application of the new EVA grade is in a pair of lifestyle shoes by Swiss brand On, whose latest Cloud 6 model features a midsole made with the renewables-based material. The new midsole delivers the same comfort, cushioning, and durability the brand is known for, while significantly lowering the product’s carbon footprint.

Samples of Cloud 6 will be on display at our booth at K Show 2025, Hall 6, Stand A43
