Allbirds Tree Runners white US 9

The Allbirds Tree Runners are lightweight, breathable sneakers designed for everyday wear, walking, and warmer weather. Made primarily from eucalyptus tree fiber, they emphasize sustainability, comfort, and minimalist style. Despite the name, they are not intended for running—they’re best suited for city walks, travel, and casual use. These shoes are praised for their barefoot-like flexibility, thermoregulating fabric, and ability to be worn sockless without odor buildup, thanks to merino wool lining.
