Allbirds Treeflyers

The Allbirds Treeflyers are designed for long distance, tempo, and race day runs. They feature neutral support and responsive underfoot feel. The Treeflyer is available in both men’s and women’s sizing, including half sizes, but unfortunately many sizes are often sold out on the Allbirds website.

Allbirds prides itself on being a sustainable brand and is a certified climate neutral business. When making the Treeflyers they use natural fibers and recycled materials such as eucalyptus tree fiber, natural rubber outsole, and merino wool heel lining. The Treeflyers have a carbon footprint of 8.09 CO2e.

The shoes feature Allbirds new SwiftFoam, a lightweight and springy midsole foam, which Allbirds claims makes every run easier on your body. There is a eucalyptus fiber upper which helps keep your foot cool during runs. The natural rubber outsole features a zonal traction pattern to give you a good grip on the road. The geometric design helps to minimize weight while maximizing cushioning.

Customers generally like the Treeflyers and found them comfortable and stylish. Multiple reviewers shared they returned to purchase multiple pairs of the Treeflyers and loved the Allbirds customer service. Negative reviews complained that the traction was poor in wet conditions. Some customers found the toe box tight and wished there was a wide option.
