adidas Adizero Adios 9 Reviews

Fast and promotes good form, but bites their Achilles.

Huge fan for parkrun and reps, but limited to twice a week due to leg fatigue.

Fast and light but tough on the knees with heavy use.

Picks it over the Evo SL for most runs: light and fast.

103 miles of intervals: light, snappy and fast with a durable outsole, but narrow (half size up) and demanding on knees.

Awesome: 120 miles of workouts, including on grass and dirt cross-country courses, with no visible outsole wear. Ideal on soft ground, where the low stack matters less.

After 50 km of everything from 1K repeats on hilly terrain, a flexible, fast shoe for their wide feet.

Calls the Adios 9 one of their favourite shoes ever, like a classic racing flat with modern materials, and very versatile: used for sprints, easy runs, a 21 km steady long run and an all-out 5k race.

About 106 miles across a 5K training block and early marathon base work: fast sessions, hill repeats and runs up to 13 miles, at a body weight of around 200 lb. They found it excellent for fast workouts and hills, with the upper, foam and outsole all holding up well and little break-in needed. Complaints are a very short tongue, flimsy-feeling laces and plenty of ground feel from the low stack. Suits speed and hill work and copes with longer runs, though they expect to use it less for the longest ones.

About 100 km in two and a half months, a low total because the shoe was hard to fit into their routine. They love how light and fast it feels and call the upper and fit perfect, but two runs of over an hour both left slight plantar fascia irritation, and the low stack felt punishing on tired legs. Best when fresh, a niche speed shoe rather than a daily trainer, and not one they would urge anyone to rush out and buy.
