How it compares
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.
What to know before buying
- Remove the insoles and laces before placing the shoes in a mesh laundry bag.
- Always use cold water and a gentle cycle with mild detergent to preserve the fibers.
- Never tumble dry; always allow the sneakers to air dry in a shaded area.
- Consider sizing up if you are between sizes, as the flexible knit provides a snug fit.
- The heel cup is structured but soft, allowing for easy slip-on transitions.
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
Sustainability & ethics
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.
Pro tip
Sprinkle a little baking soda under the castor bean insole once a month to maximize the natural moisture-wicking longevity of the eucalyptus material.
