Our Verdict

adidas Adizero Adios Pro 4

ASICS MEGABLAST

The adidas Adizero Adios Pro 4 and ASICS MEGABLAST can both handle fast running, but they're designed for very different levels of efficiency. The ASICS is a do-it-all trainer that blends bounce and cushioning with a surprisingly light feel for its category, making it versatile enough for daily miles, long runs, and even racing if you want a single shoe rotation. That said, he adidas is still the more purpose-built racing tool, with a lighter build and a carbon plate that feels more responsive and more efficient when you're pushing hard. It also delivers a more energetic, bouncier ride that helps improve running economy, letting you maintain pace with less effort.
