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.”

Works well for long runs, easy runs, threshold intervals on mixed surface.

30 mpw training for a half marathon came from the Nike Pegasus Turbo Next Nature
5/5
Overall
Great for speed work, workouts, tempos, progressions. They are very light, but work well for easy miles too.

40 mpw training for 5K and 10K came from the New Balance FuelCell Propel v4
4/5
Overall
improved cushioning, good for easy runs up to tempo, not so much for intervals. fit is a bit weird, lacing makes it hard to keep it snug and the heel is a bit loose

20 mpw training for a half marathon came from the Nike Zoom Fly SP (Special Project)
4/5
Overall
As a high school runner who doesn't want to spend 250+ on super shoes all the time this is a great alternative. This shoe with the carbon fiber infused rods gives a good push without it being too much at times like with a plate. This is very nice when you get tired because the full length plate normally messes up your form. The price is also great because you won't be scared to tear these things up because they aren't as expensive.
