Allbirds Tree Flyer 2

The Allbirds Tree Flyer 2 is a springy, everyday running shoe that blends performance feel with Allbirds’ signature natural-material approach. Built for daily training, treadmill miles, and fitness classes, it pairs a firm, responsive ride with a more secure, better-structured upper than the original. The zonal Tree Knit locks in the midfoot while staying airy up front, and the updated lugged outsole adds confidence when roads turn slick. It’s a versatile pick for runners who want stable, no-fuss cushioning that transitions easily from run to the rest of the day.

Highlights

• SwiftFoam midsole made with bio-based Pebax® for a lively, cushioned ride that stays controlled underfoot

• Bio TPU overlays on the toe and midfoot add structure, durability, and lateral stability during turns and transitions
• External heel counter improves rearfoot security and helps keep landings steady and aligned

• Machine-washable design for easy cleanup after sweaty runs, workouts, and daily wear
