Light as air. Solid as titanium.
AIRENIUM was born from the need to find a material capable of overcoming the limits of traditional PU and EVA: lighter, higher-performing, more sustainable. A concrete answer to the needs of luxury brands.
Since 1987, Tre Zeta Group has been developing materials and processes for sole production. AIRENIUM is the result of decades of applied research: a hybrid material that redefines the concept of engineered lightness, without compromising the quality of the finished product.
Density between 0.22 and 0.24 g/cm³: less weight on the sole, no compromise on design.
Top-level rebound, compression set and tearing performance. Lightness does not compromise durability.
Hybrid TPU/PU composition, enabling the recycling of both production waste and the entire finished sole.
Airenium stands apart from today’s low-density materials on the market, such as PU and EVA, thanks to innovative characteristics that meet the highest quality standards required by the industry:
Tre Zeta Group has developed a GRS-certified compounding regeneration process that transforms waste from soles made with AIRENIUM into new TPU with up to 50% recycled content. A closed-loop system where nothing goes to waste.
A versatile material, designed to meet the most diverse production needs in the world of luxury footwear.
