OrthoLite introduces sustainable footwear midsole foam

OrthoLite has unveiled a new midsole foam named Cirql rTPU30. This innovative foam is crafted using 30% recycled TPU material from post-consumer sources and is manufactured through a chemical-free, supercritical foaming process. Cirql rTPU30 offers a scalable and fully recyclable midsole solution to help footwear brands meet their climate and sustainability objectives.

Cirql’s rTPU30 meets 2024 compliance standards by incorporating 30% GRS-certified recycled TPU materials into the foam through a patented chemical-free supercritical injection foaming process exclusive to Cirql.

Glenn Barrett, the founder and CEO of OrthoLite, expressed the company’s commitment to exceeding the expectations of footwear developers seeking advanced, sustainable materials with consideration for end-of-life disposal. Barrett stated that OrthoLite is proud to address the demand from their 550+ brand partners for trusted sustainable solutions through Cirql rTPU30.

Cirql rTPU30 has undergone rigorous testing by third-party labs to ensure it meets essential midsole specifications. The material will be available with the option of a co-molded TPU outsole, eliminating the need for bonding and creating a glueless, single-material bottom unit. Additionally, Cirql’s midsole foam innovations can be conventionally bonded to all existing outsoles on the market.
