The Allbirds Tree Runner NZ takes the brand’s fan-favorite silhouette and refreshes it for everyday wear. The Tree Knit upper blends TENCEL Lyocell tree fiber with recycled polyester for a light, airy feel that keeps feet cool, while the subtle knit texture and sleek profile keep the look clean enough for anything from travel days to weekend errands.
Underfoot, a redesigned SweetFoam midsole contours for smoother, more supportive strides, and a dual-density Featherbed insole with a wool-blend sockliner adds plush comfort over long days. The NZ name nods to Allbirds’ New Zealand roots.
