What's the Allbirds story?
Co-founded by New Zealand soccer star Tim Brown and biotech engineer Joey Zwillinger, Allbirds launched in 2016 with a simple mission: create the world's most comfortable shoe using sustainable materials. Their Wool Runners became a Silicon Valley staple and sparked a revolution in natural material footwear.
What materials does Allbirds use?
Allbirds pioneered several innovative materials: ZQ-certified merino wool for breathable uppers, Tencel lyocell from sustainably harvested eucalyptus trees, SweetFoam soles made from Brazilian sugarcane, and Trino yarn blending tree fiber with merino wool. Every material is chosen for both comfort and reduced environmental impact.
How transparent is Allbirds about their carbon footprint?
Allbirds labels every product with its carbon footprint, measured in kg CO2e — a first in the fashion industry. Their average shoe produces 7.6 kg CO2e compared to the industry average of 14 kg. They offset all remaining emissions and openly share their carbon calculator methodology.
