Allbirds, Inc. 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.

Inside, a brand new dual-density insole uses cushioned memory foam, paired with Allbirds' signature wool-blend foam, to deliver uncompromising comfort that stands up to long days on feet. The Allbirds team tested more than 45 variations to find the footbed that best achieved immediate, out of the box comfort, working with a variety of vendors and testers to validate the new construction. The Tree Runner Zealand uses Allbirds' industry-leading library of natural and recycled materials to deliver a superior comfort experience.

Like its predecessor, the Tree Runner NZ's upper is made with a tree knit fiber blend, beloved for its breathability. This cool, soft and lightweight material combines TENCEL?? Lyocell with recycled polyester, delivering durability that can withstand whatever day demands.

The Tree Runner NZ upper features a uniform knit design, lending a simple, sophisticated look that transitions effortlessly through any casual setting-whether you're sipping wine at a favorite neighborhood spot or sightseeing off-the-beaten-path.
