The Allbirds Tree Dasher 2 is the next generation of the best-selling running shoe, designed to support your daily runs, walks, and workouts.


  • Shoe laces made from recycled plastic bottles
  • Responsive SweetFoam midsole made from sugarcane
  • Castor bean oil-based insole foam
  • ZQ merino wool heel lining
  • Breathable TENCEL™ Lyocell upper made from Eucalyptus Fiber
  • Natural rubber outsole with extra grip traction
  • Wide, angular heel for extra shock-absorption
  • Padded insole
  • Odor resistant


  • Midsole: Made of sugarcane-based SweetFoam. This is a biodegradable, eco-friendly alternative to petroleum based rubber. The midsole is shock-absorbent and easy to run in. It’s not too dense and feels well-cushioned, especially when navigating streets and sidewalks.
  • Ankle: The heel collar is enhanced for a better fit and to avoid slippage. Allbirds can be worn sockless, so the new heel collar ensures all users have a good fit.
  • Heel: Optimized, angular design to better absorb impact. It’s also larger than the previous model. Runners with heavy heel strike may notice the change here because the heel makes a louder sound upon impact.
  • Upper: Made from lightweight, breathable Eucalyptus tree fiber. Moisture wicking, odor resistant and soft. Stretchy and flexible to create a snug, comfortable fit.
