Eucalyptus tree fiber multipanel uppers use thin, lightweight, breathable materials to provide comfort across a wide range of temperatures
Laces made from recycled plastic bottles and eyelets made from bio-based TPU
Integrated SweetFoam® insoles underfoot help reduce the amount of material used and put your feet even closer to the cushioning
Ultralight bio-based SuperLight foam underfoot is featherlight and high performing; features approximately 70% bio-based content
Low-profile heel pockets provide an additional layer of cushioning comfort and may vary in color based on recycled materials used
FSC-certified natural rubber outsoles have high-wear and traction areas that keep the weight as low as possible while providing all-condition traction and grip
To wash, remove the laces and insoles and place shoes in a delicates bag (a pillowcase works too); choose a gentle cycle with cold water and mild detergent
Shake out any excess water and set aside to air dry (don't put the shoes in the dryer); shoes will regain their original shape with 1 or 2 wears
Hand-wash laces and insoles on their own
SuperLight Tree Runner sneakers have a carbon footprint of 2.85 kg CO2e (for comparison, a standard sneaker is about 14 kg CO2e, based on Allbirds calculations)
Allbirds is a certified B Corporation, meeting the highest standards of verified social and environmental performance, public transparency, and legal accountability
