Whether you're running a 10K or for ten minutes, the Tree Flyer 2’s comfortable, lightweight, and responsive design helps you enjoy the full experience of your run. The Tree Flyer 2 was designed with direct consumer feedback in mind, building on its predecessor to help maximize performance and minimize environmental impact. New innovations include: A flexible, breathable knit upper made with TENCEL™ Lyocell (eucalyptus tree fiber), re-engineered for a more secure fit; the upper is overlaid with bio-based TPU skins for extra support, and lined with ZQ-certified Merino wool for signature Allbirds comfort. An updated natural rubber compound and lug pattern, now perpendicular to the tread direction; this refreshed lug design functions like teeth on the road to help provide improved traction, especially on wet surfaces.Overlays on the toe and midfoot for lateral security, increased stability and durability, and element protection; and an external heel counter for back-end support and securityA heel tab to easily slip into the shoeA carbon footprint of 7.21 kg CO2e (which Allbirds offsets to zero) – that’s 2.71 kg CO2e less than its predecessor and barely half of a standard sneaker’s carbon footprint, which is about 14 kg CO2e based on our calculations.

The midsole is fine-tuned to propel you through each stride with an estimated 70% rebound rate. The SwiftFoam™ midsole is created via a single-step, highly efficient supercritical foaming process, requiring no chemical additives and a fraction of the time it takes to make traditional midsoles.
