Allbirds Tree Flyer 2 review in a nutshell: sustainably made running trainers that look and feel good for distances up to 10K.
Admittedly, I wasn’t blown away by the original Allbirds Tree Flyer, but I thought it was a good effort and hoped to see the franchise develop in the future. Intended as a tempo trainer for shorter distances, the Tree Flyer used a bio-based midsole and a naturally-made upper to maintain the sustainable image of the brand while, hopefully, making the shoes more appealing to diehard runners.
