Our Verdict

adidas Adizero Evo SL

On Cloudboom Zone

The On Cloudboom Zone and the adidas Adizero Evo SL are both unplated uptempo trainers designed to give runners a lightweight option for faster workouts, but they approach that goal differently. The Cloudboom Zone uses a PEBA-based foam, delivering a direct, grounded feel with some snap through the forefoot, though the midfoot can feel a bit flat and the overall ride less energetic than the adidas. The Evo SL, on the other hand, relies on full-length Lightstrike Pro and feels noticeably bouncier, livelier, and more fun to run in. Both are best suited for intervals, tempos, and track sessions rather than long easy runs, but the On offers a more structured and much more stable ride, whereas the adidas provides more energy return and protection.
