adidas adizero Boston 12

I did my first three marathons in the Boston 4, 5 and 6 then switched to On to change things up.  I tried the 10 and 11, both were terrible - super clunky.  The 12 is a completely different shoe, it’s fast, light, the right amount of torsion and looks nice.  It’s my go to training shoe for tempo days.  (Have two BQs and completed multiple full IMs).  There’s too much technology in other shoes to make this a race day shoe, but if carbon plates didn’t exist, this would be my shoe.

I love the balance of fit (perfect foot shape, forefoot room) heel lock down.  light weight , durability, versatility. Responsive, Bouncy and protective Cushion and performance. I use for all runs, short, long, slow , fast and road and trail. I do mountain, ultra trail running and racing. But also train for road half/marathons. This shoe is my go to most of the time. 
the lacing system and lockdown are the only flaws I see. 7-10 score there. But it’s not a deal breaker. The softer light strike 2.0 is great. Still I would love to see in the next version a better lockdown/lacing and a version called Boston Pro 13 with all lightstrike pro cushion! That would make this shoe the best! Also a trail version with same upper But continental trail grip with 3.5 mm lugs. Hallelujah! 

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.

Not a big change from previous models.  At this price range you can get other shoes better for the Boston 12 cost.

I like this shoe

I have struggled finding a neutral shoe that balances cushioning and performance when you want to squeeze the pace down in workouts or tempo runs.  The Boston 12 is really good in this aspect.  I have enjoyed it on easier aerobic runs, long runs, and workouts.  It's comfortable on foot, and it also has not caused any hot spots during runs.    

I haven't had any experience in previous models of the Boston so I won't be comparing it to those. I picked it up at 30% off RRP so was willing to give it a go for that price. The upper is a bit race-like and lacks comfort for longer runs because of this. You can tell this is a shoe that was designed to be multipurpose. If you run slow and land further back on the shoe, it feels like a comfortable easy run shoe. If you try to get moving a bit towards tempo pace it gets up and goes a little bit. The energy rods don't feel super snappy and it could be compared to the Saucony Endorphin Speed 3 in the way it's a fast trainer that can do multiple things. You definitely don't have that roll on to the forefoot like you get with Saucony's speedroll technology though. I think the flexible rods help the comfort at slower paces compared to a snappier plate. Overall an okay shoe and definitely worth the discounted price but I'm not sure I could quite justify RRP on this one.

This if my first shoe with with a stiffer forefoot via carbon rod/plate and first shoe with modern foam.  I was looking for a shoe with these features, but at a price point and durability that would make sense for a daily trainer.  I have about 80 miles on them and so far they have been a great pair of shoes.  They are much lighter than my previous Brooks Glycerin 20s.  They feel fast and slightly bouncy/springy.  I have less fatigue in my calf muscles late into runs.  If I can get several hundred miles on them I would certainly purchase again.

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

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)
