adidas Adizero Adios 9 Reviews

Seems indestructible with a good upper, but uncomfortable on long runs and no wet traction.

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

600+ km in, it's their go-to for anything up to 15K at any pace; only the side strips peeled.

Past 200 km on the Adios 9, their go-to for every workout and gym session and worn daily on two trips. It feels much more stable once you're used to it.

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.

Loves the Adios 9 and snagged two pairs; the upper is perfect: durable, light, soft and flexible. They love getting back to road feel.

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.

After 100 miles of runs up to 10 miles, workouts and strides: soft, springy, very light and as close to a perfect trainer as they've found, with no outsole wear. The catch is serious heel blistering unless they wear thick socks, and it may lack protection for long distances.

Their only shoe for about 250 km at around 4:10/km: soft and bouncy with excellent energy return, a fantastic grippy and durable outsole, and fresh legs after half-marathon-plus runs. It runs a bit big and wide and can feel unstable on easy heel-strike runs.
