Adidas Adizero Adios Pro 2 vs. Asics MetaSpeed Sky (2021)
These two carbon plate running shoes are the flagship of their respective brands in the category. The Adios Pro 2 boasts a six-carbon plate configuration (five of which are under the forefoot), while the MetaSpeed Sky uses one that is most noticeable under the heel and midfoot.
The Adios Pro 2 has a higher stack height with 39.5 mm (heel) compared to 33 mm for the MetaSpeed Sky. The drop is also higher (10 vs. 5 mm).
These characteristics translate into comfortable cushioning and a smooth ride for efficient propulsion, crafted for racing.
However, testers note that the MetaSpeed Sky’s cushioning is more explosive, especially with a more dramatic rocking motion. That’s not necessarily a good thing: this type of setup excels primarily at high speeds. Conversely, the Adios Pro platform is more versatile and allows you to enjoy runs at slower paces.
Finally, runners find the MetaSpeed Sky’s lockdown slightly more precise than the Adios Pro 2’s. It has partly to do with its ample yet not very flexible mesh that delivers a good fit.
Adios Pro or MetaSpeed Sky: which one to choose?
Overall, runners agree that the Adios Pro 2 is more versatile, but the MetaSpeed Sky is more effective if the main objective is to go fast.
Thus, the former seems to be a better choice if you want to use it for some daily training, while the latter is better suited for pure racing.
On the other hand, with its higher stack and softer cushioning, the Adios Pro 2 is more comfortable over longer distances overall.
