How it compares
The Tree Runners stand out against traditional synthetic knit sneakers by utilizing plant-based fibers that naturally wick moisture and reduce odor. While many athletic brands use petroleum-based polyesters, Allbirds focuses on regenerative agriculture and bio-based foams. Compared to recycled plastic footwear, the tree fiber construction offers superior breathability and a cooler feel against the skin, making them the preferred choice for warmer climates or high-activity days.
What to know before buying
- Select your typical size as these generally run true to size, though they will stretch slightly over time.
- Remove the insoles and laces before placing the shoes in a mesh bag for machine washing.
- Always air dry your sneakers; high heat from a dryer can damage the bio-based materials.
- Consider wearing them without socks to experience the moisture-wicking properties of the eucalyptus fiber.
- Note that while water-resistant versions exist, the standard Tree Runners are designed for maximum airflow and are not waterproof.
"The comfort level is unmatched for all-day wear, and knowing they are carbon neutral makes every step feel better for the planet." — Verified buyer
Sustainability & ethics
Allbirds maintains a rigorous commitment to environmental transparency, labeling every pair of Women's Tree Runners with its specific carbon footprint. The eucalyptus fibers are sourced from FSC-certified forests, ensuring responsible land management, while the SweetFoam soles are made from the world's first carbon-negative green EVA derived from sugarcane.
Pro tip
If you are between sizes, Allbirds recommends sizing up for the Tree collection to ensure maximum breathability and toe room.
