Bio-Based Bounce

Lightweight and super springy, our new SwiftFoam™ midsole makes your extra efforts feel effortless. It provides serious cushion and comfort, so even the toughest runs are easier on your body. And the flared, geometric design helps add stability to each and every stride.


Keep Cool And Steady

Made with breezy FSC-certified eucalyptus fibre, the supportive upper hugs your foot and keeps the air flowing for extra comfortable miles. The recycled heel counter gives you a more balanced and stable ride, so you can find your pace and forget about the rest.


Get A Grip

The Tree Flyer is a bonafide road runner. FSC-certified natural rubber tread with a zonal traction pattern gives you a strong foothold on pavement. The outsole was also engineered to flex, helping to smooth out heel-to-toe transitions and increase energy return.


Form Meets Function

We worked all the angles with our new SwiftFoam™ midsole, literally cutting corners to help give you maximum cushioning with minimal weight. But we also went wide where needed. The flared heel design adds stability and helps keep your stride smooth and steady.
