Brooks Hyperion 2 vs adidas Adizero Adios 9

The adidas Adizero Adios 9 and the Brooks Hyperion 2 are both lightweight trainers that embrace their low-stack heritage, but they differ in execution. The Adios 9 is the lighter and more stripped-down option, sitting closer to the ground with a firmer, more energetic Lightstrike Pro midsole. It's an all-in, well-executed speed shoe that excels at intervals and short races. The Hyperion 2, on the other hand, is more of a traditional lightweight daily trainer. It's heavier, not as energetic underfoot, and prioritizes durability over raw performance.
