Allbirds makes minimalist sneakers and apparel from renewable materials, chiefly merino wool and eucalyptus tree fiber, with sugarcane-based SweetFoam soles. Core styles are the Wool Runner, Tree Runner and Tree Dasher. The public benefit corporation went public on Nasdaq in 2021 at roughly a $4 billion valuation, then contracted sharply: revenue halved from its 2022 peak, and it shut its remaining US full-price stores by February 2026, shifting to e-commerce, wholesale and international distributors. On 30 March 2026 it agreed to sell its assets to American Exchange Group for $39 million.
