adidas Adizero Boston 12 Reviews
Firm, very durable and grippy for tempo days; the main complaint is heel slip and poor lockdown.

PositiveA Boston devotee went through 8 pairs of the Boston 12 in two years at about 500 km each: light, fast, reactive and grippy.

PositiveLiked the Boston 12 more than several other shoes they ran in; fast and stable, and suited every pace from 5 to 10 min/mile.

PositiveUses the Boston 12 for threshold runs and 10K workouts alongside the Supernova Prima.
Blog · Believe in the Run — Thomas, Meaghan, Robbe · summarized
Positive'The line is back': softer, more forgiving ride with a snappy toe-off, a good training partner for the Adios Pro 3 or a budget racer. All three struggled with the lacing and the very thin tongue; one tester felt forefoot toe pain that he tentatively linked to the rods.
Blog · Doctors of Running — Matt Klein, Nathan, David · summarized
PositiveMatt Klein, Nathan and David call it a major improvement over v10 and v11: softer, bouncier and lighter, and great for workouts and long rhythmic runs. They criticize the upper for poor midfoot lockdown on turns, scratchy mesh and thin heel padding. It is now a true neutral shoe and less stable than before.
Blog · Gearselected — Charles Rodmell · summarized
PositiveCharles Rodmell found it fast and fun after adjusting to the pronounced toe spring, which took about five miles and worked his hamstrings more. It excels at tempos, fartleks and long reps, though the upper lacks lockdown for short fast reps. The outsole looked almost new at 91 miles.

PositiveA 89 kg runner who found the Novablast 3 unstable took the Boston 12 on a 5k shakedown and found it fast and fun, hitting a great time without even warming up.

PositiveFinds the Boston 12 more fun and faster than the Novablast 3; pretty firm at the start but never uncomfortable.

PositiveComing back from injury, a 190 lb runner planned an easy 10k in the Boston 12 but ran a minute per mile faster in zone 2 and nearly set a 10k PB; felt real pop off the forefoot and liked its moderate firmness.
Reddit · r/RunningShoeGeeks · Apr 9, 2024 · summarized
PositivePrefers the Superblast for daily training but finds the Boston 12 a great tempo/speed shoe, very snappy in the forefoot.

MixedUses the Boston 12 for picking up speed; it takes about 1.5 miles to re-acclimate and is not very comfortable at slow paces.
Reddit · r/RunningShoeGeeks · Apr 7, 2024 · summarized
PositiveHas done 200 miles in the Boston 12 with barely any wear and calls it perhaps their favourite shoe ever: not a race shoe, but a phenomenal tempo shoe.
Reddit · r/RunningShoeGeeks · Dec 10, 2023 · summarized
PositiveAfter 545 km of the Boston 12 they'll keep buying it: best for distances up to 25 km and especially great at half-marathon distance in training. A good shoe for a beginner to train and race a half in.
YouTube comment · on kofuzi · Sep 18, 2023 · summarized
PositiveThe best all-round shoe they've tried in years, pairing with the Adios Pro 3 for 18-24 mile long runs and faster tempos; not an easy-day shoe, and the Lightstrike Pro needs 20-30 miles to break in.
YouTube comment · on kofuzi · Sep 18, 2023 · summarized
PositivePrefers it to the Deviate Nitro 2 for varied workouts, especially speed sessions; mid- and forefoot strikes roll smoothly, though the upper is subpar.
YouTube comment · on kofuzi · Sep 18, 2023 · summarized
PositiveRan a 1:28 half marathon in it, choosing it over the Takumi Sen 8, Vaporfly Next% 2 and Deviate Nitro Elite 2 because it is more comfortable and handles every pace.

PositiveAfter a 4-mile run they enjoyed the Boston 12: true to size, decently stable, great forefoot when picking up pace; only issue was heel collar and lockdown.
