Roamr TPU Air HR 85A is a structural foaming TPU within the Roamr series, specifically engineered for high-stress, high-wear, and critical support zones in footwear.

Unlike materials that chase extreme hardness, HR 85A strikes the perfect balance between stable support, responsive rebound, and long-term durability.

It ensures 3D printed shoes are not just "wearable prototypes" but durable footwear capable of long-distance walking and daily use.
