Bio-Based Midsoles

Cirql Zero36 is a new midsole solution offering a lower-impact alternative to traditional EVA midsole foams. This material innovation is 36% bio-based, fully biodegradable via industrial composting at the end of its usable life, and manufactured with a chemical-free supercritical foaming process. "We recognize that our brand partners need options that satisfy many requirements: performance, comfort, regulatory needs, scalability, climate goals and supply chain transparency, among others," said Matt Thwaites, Vice President and General Manager of Cirql, "Our aim at Cirql is to create products that make it easy for footwear brands to meet those needs, while simultaneously building a lower impact industry and a more circular future for all footwear."

Available as a finished component or polymer, Cirql Zero36 is third-party tested, and the technology is backed by 25 patents issued worldwide.
