adidas Adizero Boston 12 Reviews

Almost at 350 km on the Boston 12 and it still feels great after swapping the stock laces for better ones.

At 684.5 km their Boston 12 feels unchanged since the first kilometre, and they expect at least 1200 km from it (65 kg runner).

Retired their Boston 12 at 622 km when it felt dead as a rock. Solid for long runs, tempo and speed work up to about 450 km, and the upper and outsole still look very good.

Their Boston 12 is fantastic, with a bulletproof outsole: very little wear and great grip at 560 km.

Their Boston 12s perform consistently until retirement at 650 km, and they're about to buy a third pair.

The Boston 12 is the only shoe they want to run in: 220 miles on and it feels better than ever, and they prefer it to the Adios Pro 3.

The Boston 12 is their favourite daily trainer, with 400 km on one pair and two more boxed.

A 170 lb runner averaging 50 miles a week has hit 1,000 miles in the Boston 12 and calls it their favourite shoe: comfortable, nicely cushioned for long runs and light. The only downside is laces that come undone.

Calls the Boston 12 a tank: got 450 miles out of their first pair.

Has 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.

Has about 450 miles on both the Boston 12 and the Adios Pro 3; the Boston looks nearly new though it feels older, while the AP3's exposed foam is shredding.

Runs the Boston 12 half a size down and says its longevity is great; usually retires them around 300 miles though they could go further.

Is 915 km into a pair of the Boston 12; the outsole shows some wear but the shoe doesn't feel dead yet.

Over 730 miles across pairs of the Boston 12, retiring each around 400 miles. They think it's the best daily trainer.

After 400 km, a love-hate-love relationship: the Boston 12 is great for longer speedwork and very durable, but easy to overtighten, too narrow for some, and less comfortable than most. 7.5/10.

A long-term review after 100 miles (160 km) through a wet UK winter. They found the upper easy to lock down with no heel slip, rubbing or blisters, and it still looked almost new, while the outsole barely wore apart from some exposed midsole. The foams softened and improved with miles, making it a versatile shoe for easy, steady and marathon-training runs, but not their pick for track reps. They would like it a touch lighter, and it is not for trails.

Got over 500 good miles from the Boston 12, but when it was done it was done: the heel foam collapsed and running became uncomfortable.

Says the Boston 12 lasts practically forever, but it took about 100 miles to break in before it felt decent.

After 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.

Their Boston 12, like their other adidas shoes, got softer until about 50 miles and then stayed in the ideal range for a long time.
