Matmarket Launches Latest Version of Insite® Contoura Insoles, the Next Step in Comfort and Performance, in Collaboration with DuPont Tate & Lyle Bio Products


This week, Matmarket is launching the latest version of Insite® Contoura Insoles, featuring 25 percent bio-based Susterra® propanediol, a renewably sourced, plant-based building block that delivers high performance across a wide variety of polymer applications. Susterra® propanediol is a molecular building block that is a fundamental part of the material structure, and not simply an additive, which allows Insite® to reach new performance heights with a lower carbon footprint. Compared with conventional petroleum-based alternatives, Susterra® propanediol produces 48 percent less greenhouse gas emissions and uses 46 percent less nonrenewable energy from cradle-to-gate.

“The performance and sport science properties of Insite® insoles are industry leading, and we are happy that Matmarket chose Susterra® propanediol to help make these performance breakthroughs a reality,” said Steve Hurff, Vice President of Marketing & Sales at DuPont Tate & Lyle Bio Products. “In addition, Susterra® propanediol, a USDA Certified 100 percent bio-based product, enables a lower carbon footprint compared to petroleum-derived materials, meaning that brands and consumers no longer have to make tradeoffs for sustainability and performance.”

“We started developing with Susterra® propanediol for the sustainability benefits, however, we ended up integrating it into all of our products since the material performance alone outperformed our non-bio alternatives,” stated Gregory Diharce, Chief Product Officer at Matmarket LLC. “The partnership with Susterra® allowed us to develop compounds that enhanced material performance and durability while reducing overall weight which we have not found with any other bio-product.”

Insite® Contoura insoles use the latest in polymer science and ergonomic shape to elevate the comfort of every shoe. No longer is step-in comfort, performance and arch support exclusive of each other. Through continuing research, Insite® insoles have proven to reduce hip, knee and ankle injuries by up to 36 percent when tested against footwear without ergonomic insoles. It is the first insole technology to measure the onset of fatigue to give brands the confidence of true, all-day comfort. Now with Susterra® propanediol, we are able to produce a lighter, higher performing and more sustainable product which continues to elevate the standard in footwear comfort.
