In-Depth Review
Fibers from Nature, Performance for Life
The Allbirds Tree Runner has redefined the casual sneaker category by replacing traditional synthetics with high-performance natural materials. The upper is crafted from Tencel™ Lyocell, a fabric sourced from FSC-certified eucalyptus tree pulp. This material is not only inherently breathable but also uses significantly less water and land than traditional cotton or synthetic alternatives.
Engineering Comfort Sustainably
The comfort of the Tree Runner starts from the ground up. The midsole features Allbirds' proprietary SweetFoam®, the world's first carbon-negative green EVA made from sugarcane. The insoles are cushioned with castor bean oil and lined with ZQ Merino wool, providing natural odor resistance and moisture wicking without the need for harsh chemical treatments.
| Component | Material |
|---|---|
| Upper | FSC Certified Eucalyptus Fiber |
| Midsole | SweetFoam® (Sugarcane EVA) |
| Laces | Recycled Plastic Bottles (1 pair = 1 bottle) |
- Machine washable for extended product lifecycle.
- Silky-smooth material prevents blistering even without socks.
