Original Nike Pegasus Turbo was the first daily trainer with Zoom X foam and is innovative and a trendsetter.  It was supposed to be a training companion for VaporFly 4%. Fun fact the original Pegasus Turbo is reportedly built at the request of Eliud Kipchoge to have a training shoe that closely mimics his race day shoe. The [YouTube promo video](https://youtu.be/e6kmjDjtzEA?si=7GvD0V-arND6oQu3) for Pegasus Turbo featuring Kipchoge is slick. 

I have had two pairs of Pegasus Turbo and loved that flying experience of using Zoom X foam. It is light, extremely agile and bouncy, one of the best speed trainers I've had. Unfortunately, Nike stopped the Turbo line after v2.  

When I heard of Pegasus Turbo Next Nature I was all excited.  However, to my surprise Turbo Next Nature has a totally different story, but equally innovative as the original. It is all about sustainable shoe development.  

Finally, I got to try the shoe.  This review answers some of these questions and more

+ How does it compare to the original Turbo?
+ How is it different from the classic Pegasus line?
+ What purpose does it serve as a running shoe?

#### What makes up Pegasus Turbo Next Nature?

The shoe profile is similar to Pegasus 40 then to the original Turbo.  Here is a graphic that overlays the outlines of Pegasus Turbo Next Nature, Pegasus 40 and the original Pegasus Turbo.

</div>
</div>

When compared to the original turbo, the toe spring is less pronounced so is the heel bevel, but is better than Pegasus 40. The girth at the toe-box is much higher than the original Turbo and Peg 40.

Pegasus Turbo Next Nature has some unique features.  It is the second of Nike shoes which are branded “Next Nature”, which is Nike’s line of sustainable shoes that have more than 50% of the weight made of recycled materials. 

##### Midsole

The midsole uses two different foams - Zoom X and possibly React.  This is similar to the original Pegasus Turbo, and more recent Nike Vomero.  However, the key difference is the Zoom X foam used here is recycled scrap generated during the manufacturing process of other Nike shoes.

<div class="col-12 col-md-8 px-1">
    <LightBox src="/images/nike-peg-turbo_2.jpg" caption="" alt="" ></LightBox>
</div>
</div>

Like Pegasus, the shoe has a 10mm drop heel-to-toe drop, making it a versatile shoe and can accommodate a variety of foot strike patterns.  Stack height is 32mm, which is 1mm lower than Pegasus 40.

Midsole on the Durometer shows quite soft at about 24 HA.  Shoe as a whole weighs in at about 282 grams for Men’s 10 UK, which is on the lower average of daily trainers, and 10-15 grams lighter than Pegasus 40.

    <LightBox src="/images/nike-peg-turbo_10.jpg" caption="" alt="" ></LightBox>
</div>
</div>

##### Upper

The upper is FlyKnit, which is Nike’s brand of knit upper. Interestingly Nike claims, the yarn used is 100% recycled, and was dyed using a new process that saves 70 litres of water for every kilogram of yarn.  The upper differs from Pegasus 40 which uses an engineered mesh. I have run in a few Nike’s FlyKnit shoes in the past (Nike Free RN, Zoom Fly FK),  but this upper is the thickest I have seen. 

<div class="d-flex flex-row align-items-center justify-content-center">
<div class="col-12 col-md-8 px-1">
    <LightBox src="/images/nike-peg-turbo_7.jpg" caption="" alt="" ></LightBox>
</div>
</div>

The upper has a vibrant and intricate pattern with multiple colors, including shades of blue, pink, black and white. The swirling lines and color contrasts throughout the Flyknit adds to the visual appeal but also adds a lively look to the shoe, and makes the shoe stand out. 

The upper has five inlets for the laces, and is also missing the extra inline for heel lock lacing.  I guess this decision is because FlyKnit fits very snug to the foot, hence eliminated.  

##### Heel

Heel has decent padding, and has a stiff counter.  However the pull tab is surprisingly missing which comes as standard on all the Nike’s Flyknit shoes.  The extended bevel at the heel and harder foam 

##### Outsole

<div class="d-flex flex-row align-items-center justify-content-center">
<div class="col-12 col-md-8 px-1">
    <LightBox src="/images/nike-peg-turbo_6.jpg" caption="" alt="" ></LightBox>
</div>
</div>

Outsole has plenty of recycled rubber, which means better grip and more durability.  The lug pattern is quite unique but does have the signature of the pegasus series, and has a very good aesthetic appeal. 

#### Why did I consider this shoe?

I have had two pairs of Pegasus Turbo and loved that flying experience of using Zoom X foam. When I saw the pictures of Turbo Next Nature, it looked cool. The swirling lines and color contrasts throughout the Flyknit added to the visual appeal, and made the shoe stand out. But it's not cheap, and the price was a deterrent. 

Thankfully, it went on sale after a year or so, and I was like, "Alright, why not?" I mean, it's a Turbo, and I always loved FlyKnit. It turned out to be a good daily trainer for base building for my upcoming marathon.

#### Ride In Pegasus Turbo Next Nature

I've put over 150 kilometers on this shoe so far, and it's proving to be a very good daily trainer. No break-in is needed. I have run a few long runs over 20K including a 30K.  I have also used it for a speed workout which involved 16 repeats of 400m at VO2Max.  

I have to admit, I'm a bit disappointed with the bounce. Despite the softness of the midsole, it feels surprisingly firm. The thin insole is probably the culprit there. It feels different from the regular Pegasus in terms of ride, and the lack of Air Pockets makes it feel much flatter.

That being said, it doesn't get in the way of your running. For easy runs, it's incredibly comfortable and feels very natural. It's become my go-to shoe for those days. On speed runs, it lacks that pep and bounce I was hoping for, but it gets the job done. For long runs, it feels less "underfoot" than I'd like.

##### Fit & Comfort

<div class="d-flex flex-row align-items-center justify-content-center">
<div class="col-12 col-md-8 px-1">
    <LightBox src="/images/nike-peg-turbo_4.jpg" caption="" alt="" ></LightBox>
</div>
</div>

The upper though is of FlyKnit it is thick and not as breathable as the Pegasus.  But it offers a good fit. In fact, it's one of the best-fitting shoes I've ever worn. The toe box and forefoot are just right and mold to your foot. It reminded me of the Nike Free RN – I always loved those knit uppers. It feels very light and just fits like a glove. It’s flexible and moves with your foot. Fit wise it is much better than the Pegasus.

##### Stability

While it doesn’t have any stability features, it does feel quite stable for a shoe with a narrow base and Zoom X foam. It's as stable as the regular Pegasus. The midfoot feels stable enough. No issues there, considering the relatively lower stack height. 

The heel is perfect too. Lacing is good too. The lack of extra eyelets didn’t bother me much because the fit is perfect. That said, the laces were a bit too long and required some attention to keep them in check.

##### Road Grip 

I've found the grip to be excellent on regular roads. I couldn’t test it on slippery surfaces, but based on what I’ve seen it would probably perform well.

</div>
</div>

##### Aesthetics

This shoe is a head-turner. One of the best-looking shoes I've ever seen. Especially the upper, vibrant and intricate patterns, the swirling lines and color contrasts throughout the Flyknit it stand out. I really liked that color asymmetry that I see on my pair. I can wear it all day long. It’s a conversation starter in the running group for sure.

Nike’s Pegausus with a new sustainable twist

Nike Pegasus Turbo Next Nature


While Adidas Boston shoes have a rich heritage spanning 40 years, the modern iteration of the Adizero Boston series is relatively recent. It was only in 2010 when the Adizero and Boston shoe lines merged to create the Adizero Boston, a performance-oriented racing shoe. Now, in 2023, although the Boston line has maintained its focus on performance, it is no longer the primary racing shoe in the lineup. Starting with the Adizero Boston 10, it has become the preferred training companion to the Adios Pro, which serves as the super shoe racer in the Adizero line.

The Adizero Boston 10 [(Read our Boston 10 review here)](https://shoegeeks.in/review/adidas-adizeroboston10-001009010/) marks a significant departure from earlier Boston shoes, featuring a higher stack height. The Boston 12 continues to build on this design and is intended to be a daily trainer with the flexibility to be used for faster tempos.

Notably, the Adizero Boston 12 is one of the very few running shoes in the Adidas lineup that have been discounted in India. I purchased one during the recent Big Billion Day sale. I was eager to try it out based on positive reviews, despite having had a negative experience with the Boston 11 in the past.

_So Is the Adizero Boston 12 the perfect training companion for the Adios Pro? Does it make a versatile daily trainer?  Read as I explore its features, performance, and whether it truly lives up to its reputation._ 


<ShoeCard shoeCode="001009012M"></ShoeCard>

##### What makes up Boston 12?

To an untrained eye, the Adizero Boston 12 appears very similar to the Adios Pro 3 [(Read our Adios Pro 3 review here)](https://shoegeeks.in/review/adidas-adizeroadiospro3-001013003/), and the profile is quite similar, albeit slightly less aggressive. When placed side by side, one can observe that the Boston 12 features a more gradually tapered toe spring angle and a less aggressive heel bevel. Another noticeable difference is the dual-stacked midsole in the Boston 12.

<LightBox src="/images/adizero-boston12_1.jpg" caption="Boston 12 and Pro 3 side by side" alt="" ></LightBox>


From a technical specs perspective, the Boston 12 represents a significant performance upgrade compared to the Boston 11. The Boston 11 feels clunky when compared to the Boston 12. The Boston 12 has a 6mm heel-drop (with a 38mm heel and 31mm forefoot), while the Boston 11 has an 8mm offset. The stack height on the Boston 12 is reduced by 1.5mm to 38mm (compared to the Boston 11's 39.5mm stack). The weight has also significantly decreased, with the Boston 11 in UK size 10 weighing 306 grams, while the Boston 12 in the same size measures 279 grams.

<LightBox src="/images/adizero-boston12_13.jpg" caption="Boston 11 and 12 side by side" alt="" ></LightBox>


The shoe's geometry strikes a good balance between rocker and classic styles. The rocker doesn't feel overly aggressive but is much more pronounced than that of the Boston 11.

__Midsole__

The midsole of the Boston 12 shares a similar construction with the Boston 11. It features a dual-layered midsole with Light Strike Pro foam in the top layer, closer to the foot, and Light Strike 2.0 foam in the bottom layer. Glass fiber rods are incorporated into the midsole between the two layers. In comparison to the Boston 11, the foam quality in the Boston 12 is significantly improved. LightStrike Pro foam has a durometer of approximately 24 HA, while the new Light Strike 2.0 foam measures around 34 HA. When compared to the Boston 11's 36 HA and 45, the new midsole foam is far superior and softer.

<LightBox src="/images/adizero-boston12_8.jpg" caption="Dual-foam midsole" alt="" ></LightBox>

__Upper__

The upper undergoes a major upgrade too.  It features a much lighter mesh construction that is extremely breathable. The suede elements from the Boston 11 are absent in the Boston 12, resulting in a much lighter and more supple upper that adapts well to the feet. The tongue is minimal, with minimal padding, making it very lightweight and more racer-like in feel.

<LightBox src="/images/adizero-boston12_6.jpg" caption="Major upgrade in the upper" alt="" ></LightBox>

__Heel__

The heel of the Boston 12 has minimal padding, resembling a racer more than a trainer. However, this might not be ideal, as the heel lacks the stiffness found in the Boston 11. There is a heel tab, similar to previous editions and other shoes in the Adizero line.


__Outsole__

Like many of the shoes in the Adizero line, the outsole of the Boston 12 is made of Continental rubber. The tread pattern is designed to provide traction on most surfaces, which is beneficial for a trainer. However, the outsole is notably thinner compared to that of the Boston 11.

<LightBox src="/images/adizero-boston12_5.jpg" caption="Continental rubber outsole" alt="" ></LightBox>

##### Why did I buy it?

I am currently in the midst of a marathon training cycle, and I've been searching for a reliable daily trainer with good bounce. I came across an article on Light Strike 2.0 and heard positive feedback about the Boston 12 in various running shoe forums. Given my less-than-satisfactory experience with the Boston 11, which felt clunky and made it extremely challenging to run at faster paces, I was somewhat hesitant. However, a 50% discount offer during the Flipkart Big Billion Day sale ultimately convinced me to make the purchase.

##### Boston 12 Ride

I've covered a distance of 170 kilometers with these shoes over the past 8 weeks. Primarily, I've used them for medium-long runs, typically around the half-marathon distance. I haven't utilized them in any races, as that's not my intended purpose for these shoes, and I wouldn't recommend them for racing unless it's the only pair you have.

To evaluate the shoe's bounce and speed, I've taken it on a couple of hard tempo runs spanning 8 kilometers each. Additionally, I ran a 10-kilometer route on a soft trail around a lake bed to assess its traction.

<LightBox src="/images/adizero-boston12_2.jpg" caption="Trainer with a bent on speed" alt="" ></LightBox>

The shoe takes some getting used to, as the minimal padding can make it somewhat uncomfortable during the first few runs. However, as you become used to it, running in the shoe becomes much more comfortable. The shoe truly shines during faster runs, offering excellent bounce and stability, making it an ideal companion for the Adios Pro. Despite being a bit heavier, I found it to be more suitable for tempo runs than the Takumi Sen 9, especially on uneven roads and typical road surfaces in India.

The shoe is perfect for medium-long runs, providing ample cushioning that can carry you all the way to a marathon. If I have to compare, the ride of the shoe resembles my older Adios Pro 2 more than any other neutral trainers on the market. The ride is bouncy but not overly soft, and I wouldn't recommend it for longer runs where post-run recovery is the primary goal. For those purposes, you'd be better off with Invincibles and Superblasts.

__The reduced heel drop of 6 mm means Boston 12 is more suitable for midfoot and forefoot strikers than heel strikers.__


__Fit and Comfort__

The upper fits perfectly on the foot, especially once you've become accustomed to it after a few runs. While you can sense the lack of padding, the softer and more flexible upper doesn't cause much discomfort. The toe box suits me well as my toe shape aligns perfectly with the shoe last. However, if you have a foot shape that is more square, with toes of similar height and a wide foot, you might need to explore other options. The forefoot and midfoot fit very well.

<LightBox src="/images/adizero-boston12_4.jpg" caption="Minimally padded heel and it slips" alt="" ></LightBox>

The main issue I encountered relates to the heel. Despite the soft heel counter, the lack of padding makes it uncomfortable. Moreover, the heel tends to slip, making faster runs more challenging. I had to experiment with the lacing to achieve a satisfactory heel fit. Depending on how well the heel fits, especially if your heel is narrow, you might have to consider going half a size smaller with the Boston 12.

__Stability__ 

Compared to its racing counterpart, the Adios Pro, the shoe feels notably stable. Given its 38mm stack height, it provides impressive stability, likely attributed to the firmer Light Strike 2.0 foam in the bottom of the midsole. Although it lacks specific stability elements, it doesn't offer the same level of pronation control as stability shoes.

__Road Grip__

The shoe delivers decent road grip, making it practical for daily training with an emphasis on speed, particularly on Indian roads. While it performs well, it doesn't match the level of grip offered by Puma Grip in the Nitro line from Puma. The shoe performs admirably on softer trails with pebbles. It handles corners effectively during tempo runs. The only challenge is with roads that have loose sand and construction debris.

However, I’ve noticed the outsole tread seems to worn out a bit, but that is not out of the ordinary. 

<LightBox src="/images/adizero-boston12_14.jpg" caption="Outsole after 170kms of running" alt="" ></LightBox>


__Aesthetics & Ergonomics__

The shoe has a great presence on the road, and looks like a racer.  I really loved my colorway, which is officially called “Cloud White / Core Black / Lucid Lemon”. It doesn’t shout for any attention, but looks really great. It is easy to clean too.
