Adidas Adizero Adios 9
2025Sizes running out6.2 oz · 28/21 mm stack · 7 mm drop
Full-length Lightstrike Pro (single slab)
The Adizero Adios is the most decorated racing-flat lineage in the sport: four straight Berlin marathon world records fell in it between 2008 and 2014, the last records set before carbon plates. Since 2020 the name has been searching for a job. Race day moved to the carbon-rod Adios Pro, the 6 (2021) rebuilt the flat as a $120 speed trainer, the 8 (2023) crept back toward the old geometry, and the 9 (2025, current) went all the way back: a 6.2 oz full-length Lightstrike Pro flat with the stabilizing Torsion rods deleted, brilliant for efficient striders and a documented hazard for heel strikers. Do not confuse it with the Adios Pro, the max-stack marathon racer; this page tracks the plain Adios since 2020.

Most runners skip a version or two rather than buying every update. These compare a version against the one two updates on, with the net change rather than a single step.
We ranked the shoes that ride closest to it (a featherweight, low-stack racing flat that doubles as a speed trainer) and called out the honest differences.
