adidas Adizero Adios Pro 4 Reviews

The cutouts and soft foam make their inner ankles sore.

A cheat code at pace, but the cutout hurt their leg when they slowed and tired.

Too unstable in the heel for them, so they only use the Adios Pro 4 on flat courses up to a half marathon, though they like its fit and forefoot ride. At about 100 km they already notice the foam packing out.

The Adios Pro 4 was brilliant for them at half-marathon pace, but running slower and landing further back injured their posterior tibial, foot and knee.

A 68 kg forefoot striker's 15 km tempo run in the Adios Pro 4: lighter and much more comfortable upper than the AP3 and Boston 12, very soft and bouncy midsole, but a narrower toe box and much less stable than the AP3.

A 3:30-45 marathoner who tested them and found them too aggressive for their pace, worrying about form late in a marathon, so chose the Saucony Endorphin Pro 4 instead.

About 53 km (33 miles) covered in workouts, easy runs and a 10-mile long run. They praised the very soft, bouncy foam, the comfortable locked-in upper and an outsole with no wear yet, and found marathon pace easy to hold. They say it is not very stable and demands strong feet, that overpronators should avoid it, and that heel and midfoot strikers may find it a mixed bag. They expect less long-term durability than the Pro 3.

About 100 miles in them, mostly long runs and a 10K time trial. They loved the bounce at first and found the outsole barely worn, but the snappy feel faded after 50-60 miles into a softer ride. The heel feels wobbly, the fit runs short (a bruised toe, so size up half for long races), and it suits forefoot strikers best.

A softer, bouncier, more controllable ride with an excellent, more comfortable upper. Called a top-5 racer despite heel blisters; one tester felt it lost some stability and snappy turnover; another felt the soft heel slowed the transition. Scores 9.4-9.6.
