Our Verdict
ASICS SUPERBLAST 2
adidas Adizero Prime X 2.0 STRUNG
The ASICS SUPERBLAST 2 and the adidas Adizero Prime X 2.0 STRUNG are both maximalist, high-stack trainers, but they're tuned for very different experiences. The ASICS is lighter and has a wider platform, giving it a more stable and versatile feel that's comfortable for easy mileage as well as for faster paces. It also lacks a plate, resulting in a more natural, forgiving ride that some runners might prefer for day-to-day training. In contrast, the adidas is taller and more aggressive, with a dual carbon-infused plate and a geometry that activates best at marathon or uptempo efforts.
