What do these ratings mean?

Allbirds delivers minimalist sneakers crafted for everyday comfort with natural, breathable materials like ZQ-certified Merino wool, Tree fiber (eucalyptus TENCEL®), and bio-based SweetFoam® soles, lightweight yet supportive for urban walks, travel, or casual play. Their clean, unbranded aesthetic features recycled-polyester laces and moisture-wicking interiors that invite sock-free wear, backed by easy machine washability and all-day cushioning. Designed with versatility in mind, Allbirds shoes pair effortless style with superior softness, bouncing responsiveness, and low-maintenance durability.

Sustainability spotlight

Allbirds centers its "Flight Plan" on ambitious climate goals: halving per-unit carbon emissions by 2025 and reaching near-zero by 2030, with publicly disclosed carbon labels on every pair. Its materials mix includes regenerative Merino wool, FSC-certified eucalyptus tree fiber, sugarcane-based SweetFoam® (carbon-negative), Plant Leather (100% vegan), recycled polyester and recycled nylon. Through its ReRun™ resale platform, B-Corp status, and heavy use of ocean shipping and post-consumer recycled packaging, Allbirds ensures maximum circularity and transparency at every step.
