The Allbirds Men’s Tree Flyer Running Sneaker is designed for comfort, support, and everyday performance with a lightweight, breathable feel. Its upper is made from FSC-certified eucalyptus tree fiber knit, offering a soft and airy fit that helps keep feet cool. Underfoot, the bio-based SweetFoam® midsole delivers responsive cushioning and added stride stability, while natural rubber traction pads on the outsole provide reliable grip and lasting durability. The lace-up design with an integrated stretch-knit collar creates a secure, adaptive fit, and thoughtful details like the flared heel geometry help stabilize impact. A contoured lining also works to reduce heel slippage, making this sneaker a well-rounded choice for runners and active wearers alike.
