Ideastep RB-EVA Rubber Foam Sheet is a high-performance material specially designed for shoe insoles. With a hardness of 50±3°, it strikes the perfect balance between firm support and comfortable cushioning. Lightweight at ≤0.300 g/cm³, it ensures all-day comfort while maintaining exceptional stability.
This rubber EVA material boasts a rebound rate of ≥50%, providing responsive energy return and superior step resilience. Its tensile strength of ≥19.0 kgf/cm² guarantees reliable support and foot stability, while compression deflection ≤25% absorbs shock and pressure, reducing fatigue during extended wear.
