In-Depth Review
The Innovation of Tree Fiber
The Allbirds Tree Runner represents a pivot away from traditional synthetic footwear. The upper is constructed from TENCEL™ Lyocell, a fiber sourced from FSC-certified eucalyptus groves. This material is not only sustainable but offers superior breathability and a cooling effect, making it ideal for high-activity days or warmer climates. The production of this fiber uses 95% less water compared to traditional materials like cotton.
Underfoot Comfort: SweetFoam®
Standard sneaker midsoles are made from petroleum-based EVA. The Tree Runner features Allbirds' proprietary SweetFoam®, the world’s first carbon-negative green EVA made from Brazilian sugarcane. This material provides responsive cushioning while actively sequestering carbon during the growth of the sugarcane. The insoles are further enhanced with castor bean oil and ZQ-certified merino wool for moisture wicking and odor control.
| Component | Material |
|---|---|
| Upper | FSC Certified Eucalyptus Fiber |
| Midsole | SweetFoam® (Sugarcane EVA) |
| Laces | 100% Recycled Polyester |
| Eyelets | Bio-based TPU |
Ethics and Lifecycle
As a certified B Corp, Allbirds adheres to the highest standards of social and environmental performance. The Tree Runners are designed with a low-waste pattern-cutting technique. Furthermore, the shoes are fully machine washable, which significantly extends their usable life by allowing users to refresh them easily. At the end of their life, Allbirds partners with Soles4Souls to ensure gently used shoes are repurposed rather than discarded.
- Machine washable for longevity.
