RESPONSIVE SUPPORTIVE ATHLETIC SHOE: Our lightweight sports fitness shoe for men is designed for running, training, fitness classes, home/gym workouts, jogging, and walking. The Tree Flyer 2 lace-up sneaker offers a breathable single-piece knit upper for maximum comfort with an easy slip-on design, responsive foam, an external heel counter for enhanced stabilizing support to reduce overpronation, and cushioned SwiftFoam midsole for a springy and more responsive ride to propel you forward.
BREATHABLE UPPER: We reimagined the eucalyptus tree upper with a zonal knit which provides more breathable stretch across the top and toes, the tighter knit in the midfoot helps lock the foot in place for a comfortably secure fit and next-level all-day comfort. Sizing: a snug fit; we suggest going up a half size for a roomier fit.
EXTRA SUPPORT: Bio TPU overlays on the toe and midfoot adds stability, durability, and lateral support. Made with an updated natural rubber outsole compound, the horizontal lug pattern (designed perpendicular to your running motion) helps securely grip the road with more traction, even in wet or rainy weather.
ALL-DAY COMFORT FROM NATURAL MATERIALS: The Tree Flyer 2 is optimized for cushion, stability, support, increased traction, and responsiveness. Allbirds bouncy SwiftFoam cushioned midsole is made with biobased Pebax, a thermoplastic elastomer made from renewable sources that cushions every step. The outsole is made with FSC-certified natural rubber and the heel lining is made with ZQ Merino wool. Machine washable, simply set in a delicates bag and wash on cold gentle cycle; air dry for 24 hours.
