Roamr: 3D Printing Materials for Footwear

Roamr: Engineered for Movement

Welcome to the world of Roamr — a new high-performance materials sub-brand created for makers and designers who refuse to stay within limits. If you are looking for materials that are truly made for walking, Roamr is your answer.

Brand Philosophy: Roam & Explore

The name Roamr comes from the word “Roam” — to wander, to walk, to explore. We removed the final “e” not only as a nod to modern, minimalist technology design, but also to emphasize continuous motion and energy.Footwear and wearable products are the tools humans use to explore the world — and Roamr is the core material that powers that journey.

Motion: Engineered for dynamic, real-world movement
Freedom: Breaking free from traditional manufacturing constraints to enable complex structures
Exploration: Designed to walk with you into wider worlds

“Not just filament — but the energy beneath your feet.”

Why Roamr? The Need for a Better Balance

Siraya Tech is already a leader in foamed elastomers, with widely trusted TPU Air and PEBA Air materials. So why create Roamr? The answer lies in finding the perfect balance between performance and comfort. When developing materials for footwear, we found that existing foamed materials each excel in certain areas — but neither truly satisfies the demands of walking.

Roamr VS TPU Air & PEBA Air

TPU Air

TPU Air is lightweight and easy to print, but when used for shoe soles, it lacks sufficient energy return. Users often describe the step as flat, and under long-term load, the material can deform, resulting in insufficient support. Click to order

PEBA Air

PEBA Air delivers exceptional rebound and is widely used in high-end industrial applications. However, due to its nylon content, it feels relatively stiff. For footwear that must stay in close contact with the body for extended periods, this stiffness compromises comfort. Click to order

The Roamr Solution: Comfort-Tuned Rebound for Footwear

Roamr was created to fill this exact gap. It is a specially calibrated foamed TPU, optimized specifically for footwear comfort and walking performance. In short, Roamr gives you the rebound you want — and the softness you need.

Stronger energy return than TPU Air

Roamr delivers 48%–50% rebound, which surpasses the energy return of standard TPU Air. It eliminates the "mushy" feeling of collapsing soles, providing an upward thrust with every step.

Softer, more wearable feel than PEBA Air

By retaining TPU’s inherent flexibility and eliminating nylon stiffness, Roamr ensures comfort suitable for all-day wear.
