Cirql invited Marc to assess and review Cirql rTPU30 to gain his global perspective on the potential of our newest material to drive positive change toward a greater sustainability in footwear. Here’s what he had to say.

On Cirql rTPU30’s Applicability for Designers:

“Cirql’s rTPU30 ushers in a pivotal shift in sneaker sustainability, marrying environmental responsibility with industry demands. The scalability of rTPU30 empowers designers to innovate freely, creating customized solutions that align with a brand’s unique vision, all while utilizing supercritical foaming—a cleaner, non-toxic approach to foam creation.”

On how Cirql rTPU30 Serves Footwear Brands’ Sustainability Goals:

“This [Cirql rTPU30] midsole, a fusion of 70% virgin and 30% post-consumer TPU, sets a new standard by reducing reliance on new materials and ensuring full recyclability. Its integration of GRS-certified recycled content disrupts traditional production cycles, paving the way for cleaner, greener manufacturing.”

On Where He Sees the Most Promise to Affect Positive Change in Footwear Sustainability:

“With its dual applicability as a midsole and co-molded outsole, rTPU30 offers a complete recyclable unit, demonstrating that high-end sustainability is now within reach for everyday footwear. This isn’t just progress; it’s a transformative approach that sets a new benchmark for the entire footwear industry.”
