Allbirds introduces Tree Runner NZ

Allbirds (BIRD) is introducing the Tree Runner NZ, a new iteration of the brand’s original Tree Runner. The style is the next step in Allbirds’ core franchise strategy, as the brand refreshes fan-favorite silhouettes with even more of what consumers know and love from the originals: incredible comfort, sleek design and sustainable principles. The Tree Runner NZ uses Allbirds’ signature SweetFoam midsole, now with an updated underfoot contour for a smooth, supportive stride. A stack height of 10.2mm at the forefoot and 20.0mm at the heel lends a naturally grounded feel when you’re on the go. The style also comes with a wool-blend collar and tongue lining to hug the foot for a snug, plush feel where you need it most.
