Step into ‘The Material Effect’ journey

Footwear Evolution: Performance, Sustainability, Efficiency

Today’s consumers expect footwear that performs on every level – from athletic output and impact protection to lightweight comfort in daily wear. The midsole plays a central role, delivering energy-return, cushioning, and durability across use cases. Purchasing decisions are increasingly influenced by environmental impact, with growing attention to how products are made. 

This dual challenge requires footwear brands to adopt advanced materials that deliver performance while supporting smarter, cleaner, and more scalable manufacturing.

We're seeing growing demand for materials that deliver both elite performance and sustainability. Desmopan® FLY unlocks new possibilities with optimized processing, offering lightweight resilience, long-term durability, and efficient recyclability to help shape the future of high-performance footwear.
