Adidas AdiZero Boston 12 Introduction
I’ve fond recollections of my very first Adidas Boston (which was the fifth model). On the time, it had all I wished in a operating shoe: it was mild, it was lean and it had sufficient cushioning for the quick to medium distance runs I used to be doing.
The Boston 5 was a really totally different beast to at this time’s Boston as we all know it. These have been the times when lean and minimal have been nonetheless traits that individuals wished in a operating shoe. The Boston 9 and earlier variations have been designed to be versatile, light-weight trainers for uptempo runs, day by day runs and even racing.
The Boston of at this time fills a very totally different position within the Adidas lineup. It’s designed to be a pace trainer: a extra sturdy, cheaper model of their flagship marathon racer, the Adios Professional 3.
The final Boston model that I examined was the tenth model. I loved testing it however I felt prefer it was extra of a simple day/long term shoe than a pace coach. I preferred how stiff its midsole was however I discovered it a bit too agency for lengthy distances.
The Boston 11 was solely an higher replace however the brand new Boston 12 has been totally refreshed. It now weighs 9.4 oz (267 g) which is 0.2 oz (6 g) lighter than the earlier model however a lot heavier than rivals just like the Magic Pace 3 and Razor 4. It additionally has a thinner midsole than the Boston 11 and its value stays $160 which is the typical value for a plated, pace coach.
Adidas AdiZero Boston 12 First Impressions
My first run was a simple 41 kilometres proper out of the field. At first, it felt a bit stiff and blocky however after 20 kilometres, the shoe broke in and it felt a lot better.
Essentially the most noticeable adjustments have been the forefoot stiffness and the journey softness. The forefoot felt far more versatile so there was much less of a rockered journey. The midsole felt a bit of bit softer than the Boston 10’s midsole and it had sufficient cushioning for the complete distance.
On that first run, it didn’t strike me as a pace coach. It felt like a day by day coach with relaxed transitions. It additionally didn’t really feel as energy-saving because the Boston 10 as a result of the forefoot rocker wasn’t as aggressive.
I additionally seen some slight discomfort on the slim midfoot the place it poked into my arch but it surely didn’t trigger any blisters. That is one thing that I by no means skilled with the Boston 10.
Adidas AdiZero Boston 12 Higher
The Boston 12’s higher is lighter and extra versatile than the earlier model however I don’t discover it very snug. Essentially the most annoying factor is the skinny, ungusseted tongue which slides downwards throughout runs and bunches up on the backside of the lacing space.
The lacing system doesn’t work very properly and I’ve to cease to regulate the lacing a number of occasions throughout lengthy runs as a result of it creates stress spots on the highest of my foot.
I discover the heel match unfastened. The issue is that I can’t tie the laces too tight or I really feel the lacing stress. I used a runner’s knot however I nonetheless expertise a unfastened heel match which makes the higher really feel sloppy.
The forefoot and toe field are effective however the midfoot is slim which causes some arch stress. This may be a difficulty for wide-footed runners or runners with flat fleet. The match is true to dimension and works finest for me with medium or thick socks.
Adidas AdiZero Boston 12 Sole Unit
The suggestions from the Boston 10 and 11 was that they have been too agency and too heavy so Adidas has addressed this by including extra Lightstrike Professional foam into the midsole and lowering the quantity of Lightstrike. They’ve additionally modified to Lightstrike Professional 2.0 because the firmer backside layer of the midsole which gives additional stability and sturdiness.
I don’t discover an enormous distinction between Lightstrike Professional 2.0 and the unique model of it as a result of it’s EVA- it nonetheless looks like a midsole foam from 4 years in the past. The Boston 12’s new midsole doesn’t ship much more power return but it surely does really feel extra forgiving than the Boston 10 and after my long term, my legs felt nice. It positively has sufficient cushioning for a full marathon.
The glass-fibre power rods within the midsole have additionally been tweaked. They’re extra versatile than within the Boston 10 so the 12 has a extra versatile forefoot with a much less outstanding forefoot rocker. This was a mistake for my part. The stiff forefoot of model 10 gave it a extra related journey to the Adios Professional 3. It used to really feel extra environment friendly over lengthy distances.
There’s no extra plate below the heel like within the final 2 variations so the journey feels smoother and extra constant now. Beneath the heel is a pretzel form which is related to the Energyrods.
I discover that the Boston 12 is finest for straightforward runs. It’s not notably mild and it’s not very energetic so it doesn’t actually encourage me to choose up the tempo. Its weight and its journey make it really feel a bit clunky to me so it leans extra in the direction of a day by day coach than a exercise shoe.
The Boston 12’s sturdy outsole is its finest characteristic. It has thick, grippy Continental rubber which is able to final a really, very very long time. There’s little or no put on displaying on my pair after the testing interval. I additionally discover that the uncovered Lightstrike midsole is sturdy so it received’t put on down prematurely.
Adidas AdiZero Boston 12 Conclusions

The adjustments have moved it extra in the direction of a day by day coach than a pace coach or exercise shoe. They have already got the Photo voltaic Enhance, Photo voltaic Glide and Supernova for day by day coaching. I might have been proud of a Boston replace with a softer journey, a extra aggressive rocker and a wider midfoot.
