In-Depth Review
Material Science: The Power of Eucalyptus
The Allbirds Tree Runner is a paradigm shift in footwear construction. Unlike traditional sneakers that rely on synthetic nylon or polyester, the upper of the Tree Runner is knitted using TENCEL™ Lyocell. This fiber is derived from FSC® Certified eucalyptus trees, which are grown in sustainably managed forests. The production process uses 95% less water than traditional cotton and has a significantly lower carbon footprint.
Revolutionary Sole Technology
The midsole features Allbirds' proprietary SweetFoam®, the world’s first carbon-negative green EVA. This material is made from sugarcane sourced from Brazil, processed in a mill that runs on renewable energy. Unlike petroleum-based foams, SweetFoam® actually sequesters carbon during its growth phase. The laces are made from 100% recycled plastic bottles, and the insoles are crafted from castor bean oil and ZQ-certified merino wool.

| Upper | FSC Certified Eucalyptus Fiber |
| Midsole | SweetFoam® (Sugarcane) |
| Insole | Castor Bean Oil & Merino Wool |
| Laces | Recycled Plastic Bottles |

The Tree Runner is designed with the 'end of life' in mind. By avoiding complex mixed-material glues and focusing on high-quality natural fibers, Allbirds creates a product that is not only durable but fits into a more circular economic model.
