Allbirds released the Tree Runner Go, an addition to its Tree franchise, offering “extra cushioning and improved durability, packaged in a light, breezy material that’s great for when you’re on the go.”

The company reported that the Tree Runner Go “draws inspiration from the company’s best-selling silhouette, the Tree Runner, with multiple innovations and upgrades,” including:

  • Breathable Upper: Allbirds’s Tree material combines tree fiber–Tencel Lyocell with recycled polyester for a “cool, soft and lightweight feel.” The added recycled poly “improves material strength, flexibility and durability plus recycled poly has a lower climate impact than conventional virgin polyester.”
  • Durability: The upper is made with a “new yarn spinning technique that improves durability by up to 50 times.”
  • Ultra-Cushioned Midsole: Allbirds SweetFoam underfoot offers a height of 45.5mm at midfoot, “lending a cushioned, forgiving feel—14 percent more SweetFoam underfoot and 12mm more height than Allbirds Tree Runner.” SweetFoam is made with sugarcane-derived Green EVA, “unlike plastic, petroleum-based midsole foams often used in footwear.”
  • Elevated Design: Fine knit detailing across the upper and a new midsole look with line detailing “add texture and expression for a more refined look that transitions seamlessly throughout the different parts of your day.”

The Tree Runner Go is available in full and half sizes for men and women in five colorways.
