adidas Adizero Adios 9 Reviews

They occasionally run steep climbs in the Adios 9, which they find fun and relatively poppy compared with their mountain flats.

Loves the Adios 9, which they think has the same foam as the Adios Pro 4 without rods or plate; a little firmer with more ground feel, perfect for threshold and faster, and works better for them than the Evo SL.

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 first run in the Adios 9 made them smile right away: good ground feel without harshness, and a strong 7K with intervals on tired legs.

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.

About 45 km (28 miles) of speed sessions, easy 10-12 km runs and hills. They praise the flexible, light, slipper-like feel, the soft stretchy upper with padded heel, excellent grip on wet and dry surfaces and the lively foam. They found it best for short fast reps and easy running, but the laces are poor, a sensitive arch may notice the midfoot shank, and how long the foam lasts is still unknown.
