AllBirds pride themselves on the comfort of their shoes. Not only do their respectfully sourced materials lend an unmatched level of comfort to their shoes, but the brand also strives to accommodate all types of feet, including the wide and flat. A savant mix of merino wool, tree fibers, natural yarn, and more unexpected materials like sugarcane all come together to create unmatched comfort which gives Allbirds their signature "walking on clouds" feel.
