Allbirds Tree Dasher 2.0 vs Salomon S/Lab Phantasm CF: Two Very Different Running Shoes

A sustainable everyday trainer with a eucalyptus upper meets a race day super shoe with a rocker-focused plate. Here is how they compare.

Introduction

These two running shoes sit at opposite ends of the spectrum. The Allbirds Tree Dasher 2.0 is built around sustainability, with plant-based materials throughout its construction. The Salomon S/Lab Phantasm CF is a race day super shoe designed for speed. If you are choosing between them, you are really choosing between a comfortable everyday option and a purpose-built racing tool.

Allbirds Tree Dasher 2.0

Allbirds is one of the most sustainable shoe companies in the world, and that ethos runs through every part of the Tree Dasher 2.0. The upper is made from natural eucalyptus, the midsole uses SweetFoam derived from the remnants of sugar cane processing, and the outsole is built on natural rubber.

The eucalyptus upper feels noticeably different from conventional knit uppers, and the SweetFoam midsole gives the shoe a soft, easygoing ride that suits daily miles. One thing to keep in mind: the fit may run a bit long, so it is worth checking sizing carefully before ordering.

If low environmental impact matters to you, this is one of the more convincing sustainable running shoes available, since the commitment extends beyond marketing into the actual materials.

Salomon S/Lab Phantasm CF

The Phantasm CF is Salomon’s race day super shoe, and its character comes from how the plate is used. Rather than delivering a pronounced popping propulsion feel, the plate works structurally to reinforce the rocker geometry, similar in spirit to the Carbon X approach.

The midsole is an EVA-type foam that feels soft and bouncy, and the rocker makes toe-off feel smooth and efficient. The trade-off is the upper: the long, crinkled tongue tends to twist when you are putting the shoe on, which can make getting ready on race morning a small battle.

Sizing is also worth watching. In testing, a size that should have fit closer to a smaller size had significant extra room in the toe box, so the fit may run long. If possible, try before you buy.

Which One Should You Pick?

If you want a daily trainer with genuinely sustainable materials and a comfortable, forgiving ride, the Tree Dasher 2.0 makes sense. If you are lining up for a race and want a super shoe with strong rocker geometry and bouncy foam, the Phantasm CF is the tool for the job, with the caveat of the fiddly tongue and potentially long fit.

Conclusion

Both shoes do their jobs well. The Tree Dasher 2.0 stands out for sustainability and everyday comfort, while the Phantasm CF earns its place on race day with smooth rocker mechanics and a lively foam ride. Just check the sizing on either before committing.
