How it ranks
The adidas adizero Boston 12 ranks among the stronger daily trainers in our data. Looks and durability are its strongest sub-ratings. Comfort scores well below its other sub-ratings. The rating rests on 58 runner reviews and 10 other rated shoes in the adizero Boston product line.
Confidence
How settled the rating is against every other rated shoe. A shoe can rate high on confidence with relatively few reviews of its own when its product line has a long record and external ratings from retailer sites agree. Confidence will score low when we have few ratings or when runners disagree.
Confidence
95/100
“Fit quite long and wide—size down half a size.”
“Laces are absolute garbage; come undone during runs.”
“Forces you up onto your toes, helping increase cadence and decrease overstriding.”
“Runs about ½ size bigger than Saucony and Nike.”
“Lasted only 200 miles before sides separated from base.”
“Outsole is grippy and looks new after 100km.”
“Needs about 30 miles to break in; feels overly firm before that.”
“Less calf muscle fatigue late into runs.”
“Rolls through the toe with obvious ease.”
“Upper is race-like and lacks comfort for longer runs.”

Great shoe, really responsive. Only issue was that it lasted just 200 mikes before the sides separated from the base

80 mpw training for 5K and 10K came from the adidas adizero Boston 10

I thought the Boston is not getting enough credit for what it’s worth for my threshold trainings (not a race shoe but amazing for 1-3k reps, temporuns etc)

70 mpw training for a marathon came from the Nike Air Zoom Pegasus 40
5/5
Overall
This shoe is so ugly. My first high stack height shoe, and honestly, I almost couldn't pull the trigger to buy them. I've always run in lower, lighter shoes from Adidas. But, wow! Once I got these on and put in a few miles, the ease with which these roll through the toe was just obvious. It is so much less effort to keep the cadence up and get this aging frame through those easy miles. While I won't convert to this shoe entirely, a pair will certainly remain in the shoe rack for easy distance runs in smooth terrain.
