High-performance Strobel insole materials for strength and comfort

  • Strobel insole

    Strobel insole (spunbond) – lightweight strength for every step

    We offer our spunbond Strobel insole as a lightweight yet durable foundation for modern footwear construction. Engineered with isotropic strength and dimensional stability, it delivers excellent stitch-hold and high cutting yield - ideal for Strobel and insole board applications. Available with GRS-certified recycled content, these materials support responsible manufacturing and traceable sourcing. By combining high performance with resource-efficient production, we help customers reduce waste while delivering lasting comfort and durability.

  • Injection Strobel – engineered by us for high-performance footwear

    We design our injection Strobel insole to meet the rigorous demands of direct injection molding. With excellent dimensional stability and bonding performance under heat and pressure, it is the trusted solution for work, safety, and high-performance shoes. Crafted with over 70% recycled post-consumer PET and available h dye-free, chemical binder-free process, delivering a cleaner and more resource-efficient manufacturing solution.

  • Binder-free insoles – Performance with recycled content and cleaner production

    Developed for customers seeking durable, lightweight material solutions, our binder-free insoles combine reliable performance with responsible material choices. Produced without chemical binders, they support cleaner manufacturing while maintaining excellent mechanical strength. Made with up to 100% GRS-certified recycled polyester, these clean-cutting materials help improve material utilization, reduce waste, and support circular product design.

Expert voice

“Sustainability remains a dominant topic, evolving from simple concepts such as "reduce, reuse, and recycle" to a stronger focus on traceability and carbon emissions. To meet these targets, there will be a greater push towards developing materials with lower environmental impact and improving production efficiency by reducing energy consumption or stepping up the use of alternative energy sources.”
