When compared to traditional synthetic mesh sneakers, the Men's Tree Runners offer superior temperature regulation due to the natural cooling properties of eucalyptus fibers. Unlike standard leather or plastic-based trainers, Allbirds utilizes a carbon-offsetting program that addresses the entire lifecycle of the product. While they lack the aggressive grip of dedicated trail running shoes, they provide a much smoother, bridge-to-street aesthetic than most performance-only footwear.
The Men's Tree Runners are the most comfortable sneakers I have ever owned for summer walks, and I love that they are completely vegan and carbon-neutral. — Verified buyer
Allbirds maintains high ethical standards by using FSC-certified eucalyptus trees, which rely on rainfall rather than irrigation. The brand is a certified B Corp, ensuring rigorous social and environmental performance, and the SweetFoam midsole is the world's first carbon-negative green EVA. Packaging is made from 90% recycled cardboard and serves as both the shipping box and the shoebox.
Sprinkle a little baking soda under the castor bean insole once a month to maximize the natural moisture-wicking longevity of the eucalyptus material.
