Our Verdict

adidas Adizero Adios Pro 4

adidas Adizero Prime X3 STRUNG

The adidas Adizero Prime X3 Strung and the adidas Adizero Adios Pro 4 may share a family name and a big chunk of Lightstrike Pro foam, but they're built for very different purposes. The Prime X3 is a super trainer: heavier, much higher stacked, and far more cushioned, with a dual propulsion system that delivers huge rebound but feels too bulky to race efficiently. The Adios Pro 4 is the true super shoe in the lineup: lighter, snappier, and more energetic thanks to its carbon Energy Rods and firmer, more responsive forefoot. The Prime X3 offers more protection and long-run comfort, making it ideal for marathon-pace training blocks, while the Adios Pro 4 provides better efficiency, quicker turnover, and a more race-ready feel for half marathons and full marathons.
