Women's Tree Breezers - Jet Black (Black Sole)

The Women's Tree Breezer in Jet Black with a black sole is a lightweight ballet flat from Allbirds that the brand says needs no breaking in. Its knit upper is made from eucalyptus-derived TENCEL Lyocell and recycled polyester, with a stretchy, fitted collar that moves with your foot. Inside is a plush bio-based polyurethane insole foam and a soft Merino wool insole lining, which Allbirds says is responsibly sourced. The brand suggests it for commuting, travelling, walking, the office and evenings out. It weighs 4.1oz in women's size 7 and is made in Vietnam. It comes in women's sizes 5 to 11, including half sizes. The flat is machine washable; remove the insoles, hand wash them separately and let everything air dry.
