    My Thoughts on Adidas Ultra Boost V2.0

    More photos

    At this point, almost everyone has heard of the Adidas Boost technology.

    The Adidas Ultra Boost is one of the most comfortable and responsive shoes I have worn, and one of the sexiest too, but it came at a hefty price.

     

    Comfort/Midsole

    After putting over 500 miles on these shoes, the Ultra Boost has served me well for both short and long runs. Although a lot of people have complained about the breathability of the shoe, I never had an issue with this.

    The primeknit fit my feet well and never felt too constrictive. The lightweight design never felt like it was weighing my feet down, even 10 miles into a run.

    As you start seeing the outsole wear out, you will barely notice a difference in the comfort of the Boost midsole. It stays just as comfortable and responsive 300 miles in as it did the day you put it on.

    One issue I did have with these was when I would stand for a long time, they made my heels hurt. If you're not moving for a long time the shoe can get a bit uncomfortable, almost as if it was too soft.

     

    Looks

    This has to be the best-looking shoe you could wear. It goes with absolutely everything. Put on some shorts and go running. Come back, shower hopefully, and put on some casual clothes and put these suckers back on. They go well with any outfit you could think of.

    There are more color options for you to pick from than I could name here. Warning, some of the more exclusive colors can go for hundreds if not thousands of dollars. Absolutely insane!

    Due to the overall popularity of these, they can be hard to find in your preferred color and shoe size so be ready to shop around a bit.

     

    Outsole

    I own the Adidas Ultra Boost 2.0. The 1.0 had a lot of issues with the outsole wearing out too fast but with the 2.0 and forward, Adidas introduced the much more durable and grippy Continental outsole. Running hundreds of miles, and wearing them often to school and around town, my Ultra Boost finally started cracking and wore off after one year.

    As long as you get a pair with the Continental rubber outsole, these will last you for hundreds of miles. They have great tracking no matter the conditions due to the Continental rubber outsole. Don't get caught in heavy rain in these though, you'll feel like you are running in a swamp.

     

    Price

    Ah, the price. Short and to the point - way too expensive! What the heck is Adidas thinking about making these $180?

    The hype around these shoes for runners and casuals means that these shoes never go on sale, and finding them in your size can be a challenge in itself.

    Pros

    • Incredibly comfortable
    • Lightweight
    • Stays responsive no matter how many miles you put on them
    • The 2.0 and forward have a durable outsole
    • Great design
    • Large color selection
    • Soft inner lining

    Cons

    • PRICE!
    • Certain models can be hard to find in your size
    • The plastic pieces scratch easily
    • The white boost yellows with time, unwashable
    • Gets wet easily in rain

    Conclusion

    The Adidas Ultra Boost is an incredibly expensive but a versatile shoe. Whether you're running a half marathon or going out on a date, these will serve you well. The price tag is heavy but they are a good value due to the hundreds of miles you will get out of them.

    The shoe is lightweight, breathable, and comfortable making it the only shoe to date I would wear without a sock. I would not recommend it to anyone in a really wet climate as these don't mix well with rain.

    Price tag aside, these were the first Adidas Boost I purchased. I instantly fell in love and now own 7 different models.

    Adidas Ultra Boost after 50 miles and a lot of travel

    I initially bought the Adidas Ultra Boost because I was traveling a lot for work, and I needed a shoe that could transition from a run to looking 'ok' with jeans if I needed to meet up with co-workers in the evening.

    I also needed a shoe that provided enough cushion since I was still recovering from foot surgery. Overall, I think this shoe definitely checked all the boxes for what I was looking for, but I probably wouldn’t use it for my daily trainer

    Upper

    The shoe has a thick single-piece knit upper that is flexible and allows your toes to splay in the toe box.

     

     

    This was really important to me since some shoes rub too much and cause blisters or result in another lost toenail. While flexible, the upper seemed durable and I don’t feel like it will wear down and create a hole.

    Midsole

    The midsole, however, is the star of the show and I think the reason is the Boost line. The midsole is Boost material throughout so you get that nice bouncy midsole from the heel to the toe. 

    Collar

    The ankle collar has a lot of thick padding, which I think is to keep it secure. 

    But I found that it added a lot of extra weight and wasn’t too supportive. The tab at the back of the collar was nice since it helped get in and out of the shoe quickly. 

     

    Shoelace

    The shoelaces are attached using this thick plastic piece that I feel didn’t allow for good lockdown since it created a lot of pressure points.

    This was definitely my biggest problem while running in the shoe since I didn’t feel like I could make a lot of lateral movements. 

    Outsole

    The shoe’s outsole is a grippy continental rubber. The outsole is nice, but it’s very thin and is wearing down quickly after 50 miles running and a lot of walking.

    This shoe is also not ideal for anything beyond pavement or a hard-packed trail since you won’t really get a good grip on any other surface.

    Weight

    This shoe is heavy! Don’t expect a lightweight foam shoe like the Vaporfly, but you definitely get the benefit of the energy return from all that beautiful Boost material.

    Performance

    In short, this was a fun shoe to run in. My favorite type of running to do in the shoe is hill repeats.  

    The forefoot of the shoe is thinner but well cushioned for the uphill and springy comfortable on the downhills. It is a very cushioned shoe and I found that I could do treadmill runs, outdoor long runs and everything in between with very few issues. 

     

     

    I found that the energy return made me feel like I'm faster than my normal runs, which is generally the pace of a turtle running through peanut butter.

    I ran into some issues when I tried to take corners or do lateral movements. I found that my foot was moving around a lot in the shoe since my foot wasn’t very secure in it. If you don’t do a lot of sharp turns or have a foot shape that lends itself to a good lockdown in this shoe, you probably won’t have any issues. 

    Value

    This is an expensive shoe, especially considering the durability factors mentioned above. However, if you opt for the Parley version, you can take solace in the fact that you are contributing to less ocean plastic. Also, it is definitely good looking.

    Pros

    • Cushioning
    • Very responsive and springy ride
    • Flexible midsole
    • Knit upper is comfortable and doesn’t restrict foot
    • Stylish shoe that you can walk around in
    • Fit true to size

    Cons

    • Heavy
    • Lockdown is either difficult or uncomfortable
    • Not well suited for surfaces beyond pavement or treadmill
    • Durability concerns with the outsole

  • 70 / 100 | The Ginger Runner | | Level 5 expert

    I think there's room for improvement on this shoe because I can definitely see the benefits of going with a Boost long-form shoe. Something that will take you on those long, long runs, Marathon, maybe even beyond. There's just some elements [that] I think need a little fixing.

    The boost material on the Ultra Boost is just amazing.

Become an expert

- Adidas hypes the Adidas Ultraboost as “the best running shoe ever.” Such a bold claim is primarily anchored on its innovative and revolutionary Boost midsole foam that is not only very cushioned but also superbly responsive. The superior responsiveness of the shoe is supported by The Three Stripes’ assertion that it is 20% more responsive than any of the Boost models.

- More than just the extremely responsive and cushioned midsole, the Ultraboost boasts of ¾ one-piece Primeknit upper that hugs the foot in comfort. A Stretchweb outsole delivers more than adequate grip on the road and light trail while the newly designed split heel counter prevents slippage in this area and eases the pressure off of the Achilles.

The fit of the Ultraboost is unbelievably comfortable. Besides the generous padding all throughout, runners with average dimensions in their feet will love the adequate space in the heel, the secured midfoot, and the wide toe box. Available widths are the standard D for the men’s and B for the women’s.


The outsole literally resembles the form of a web as it is rightfully called the Stretchweb. Like a real web that adjusts to the spider’s movement, Adidas’ proprietary outsole rubber adapts and stretches to maximize the power of every stride. Additionally, it offers flexibility and an element of natural running.


The midsole is undoubtedly the domain of 3,000 blown TPU energy capsules. According to Adidas, the Ultraboost has an astounding 20% more of these shock-absorbing and responsive thermoplastic polyurethane (TPU) pellets than any of the other Boost models. It means that there are 20% more pellets that lock themselves together to take on the impact of every stride and convert the same impact for a truly responsive ride. The same midsole element is used in the new Adidas Ultraboost 19

Another technology in the midsole is the Torsion System or the plastic bridge insert that offers torsional stability and enhanced transition without adding weight.


An engineered mesh that has precise stretch points that hugs the foot like a second skin. Adidas’ digital knitting process uses synthetic yarn that produces extremely breathable, supportive, and lightweight one-piece upper. Altogether, the engineered mesh and Primeknit material, adapt to the runner’s foot while offering maximum comfort and support.

Inside the shoe is a lightweight sockliner that enhances the plush comfort even more.

One very noticeable part of the upper is the sleek and catchy heel counter that cradles the foot in support and prevents untoward movement in this area. Comfort and stability are offered by this innovative heel structure.

The Ultraboost is one of the flagship shoes in the Adidas stable of performance products. Many people have stood by this road companion’s capacity to provide enjoyment throughout the running sessions. The Boost™ technology certainly gained traction as one of the most reliable cushioning systems in the world, especially since many people have taken the time to experience it and feel the reactive and impact-resistant nature of the amalgamated thermoplastic polyurethane (TPU) pellets. It’s clear from the start that boost™ was here to stay.

Interestingly, most shoe companies didn’t immediately challenge the popularity of Boost™. In fact, the widely used ethylene-vinyl acetate (EVA) didn’t phase out over the decades. A bevy of road running shoes still continues the trend of EVA utilization, though the need for innovation and change eventually stirred the companies to a thoughtful implementation of creativity and scientific methods. Midsoles apparently needed to be bettered to retain consumer interest and, maybe, encourage new ones.

The need to innovate

Nike, arguably one of Adidas’ most prominent competitors, sought runners out, asking them what they wanted for their running shoes. The general consensus was that people just wanted a cushioning system that offered high levels of energy-return, a lightweight ride, and flexible experience that accommodated the natural movement capacity of the foot.

The challenge for Nike was creating a technology that would permit such desires and implementing it in shoes that kept up with the current expectations of consumers. Enter the “React” foam and the Nike Epic React Flyknit. It’s not the first shoe to ever use the React, but it’s the one that people are comparing to the Adidas Ultraboost the most.

Let’s get to know what Nike did to challenge Adidas’ licensed midsole technology. But it’s also good to see the rest of the features in each shoe.

The material composition of Ultraboost and Epic React Flyknit

The outsole units of the Ultraboost and the Epic React Flyknit are the ones that bear the most difference; while the former has a rubber compound that fills the surface of the sole unit like a grid or web, the latter only has rubber on the heel and forefoot to ensure targeted protection and traction.

The upper unit of the Adidas Ultraboost is made of engineered mesh, a material that has a cloth-like quality. It’s relatively well-known and is used in many running shoes. On the other hand, Nike’s offering is graced with the proprietary Flyknit material, a knitted textile that is stretchy yet securely woven. It is one of the first knit-uppers to ever be featured in the market. A cleatie construction allows people to experience a sock-like fit, though a lacing system is still in place.

Now, to the midsole. It’s always been clear that Boost™ is the main competition of the React foam, but the latter is vastly different in design. The compacted TPU pellets of Adidas’ line works to provide a springy and well-cushioned ride. The React aims to do that and more.

Nike’s creative minds created the formulation of the React unit to welcome the desire for balance in every aspect of the performance. They wanted to give a luxurious underfoot experience and a springy ride without putting too much weight, sacrificing flexibility or bringing too much energy-return. The piece that went out of the mold is arguably more substantial in form than the one licensed by Adidas. No compaction was involved as it’s a single-piece foam. Ripple-grooves (zigzagging trenches that line the external surface of the material) help in heightening responsiveness and flexibility.

To add extra structure to the underfoot experience, both companies employed their own version of an underfoot support unit. Adidas utilized the Torsion System, a thermoplastic layer in the midsole, to support the muscles and tendons of the midfoot. Nike’s choice was an injected heel clip that can be clearly seen from the back of the shoe. The task of this clip is to stabilize the heel of the foot while also attenuating impact shock.

A healthy competition

Many elements of the offerings from Adidas and Nike are stark images of each other. While some of them may be implemented in unique ways, it’s clear that they’re all for the betterment of a person’s performance.

Adidas paved the way for running shoes that are of superb quality. Every year, the brand finds new ways to make the running experience as pleasant as possible. Nike and other companies are also part of this cycle of innovation and integration. The Ultraboost and the Epic React Flyknit are only two examples of friendly competition causing positive waves to the sports industry. There are more to come, and inventors and shoemakers are there to see them through.

Neutral shoes similar to the Adidas Ultraboost

Brooks Glycerin 16

The Glycerin series has always been a pinnacle when it comes to providing copious amounts of underfoot comfort and excellent performance on the roads. People were highly appreciative of it as it’s apparently one of the neutral running shoes that have cared for their feet during their time on both flat surfaces and groomed trails. The new DNA Loft midsole technology also received waves of positivity for being highly responsive and durable. Even the design was given due praise for improving upon its immediate predecessor and working its way towards a simple yet contemporary look that’s great for both exercise and daily walks.

Altra Escalante 1.5

The Zero Drop specialization of Altra Running is in full swing with the Escalante 1.5. This shoe can be worn for daily speed training, yet it can help in doling out high levels of performance during races. The external pad features the FootPod technology, a pattern of grooves and traction centers that complement the bending capacity of the tendons and joints of the foot. A full-length, foot-shaped foam with a roomy forefoot construction permits the relaxation of the toes. Rounding out these form-accommodating elements are the InnerFlex midsole-integrated flex channels and the stretchy yet cloth-like engineered knit façade.

Skechers GOrun Ride 7

The Skechers brand has always been interested in perfecting the running form of a person. In fact, the designs of their shoes encourage an apparently more efficient way of taking each step, particularly the midfoot-striking technique. The GOrun Ride series has always been a proponent of such a method, and it is one of the reasons why the GOrun Ride 7 still has the Skechers-led Midfoot Strike Zone technology, which is fundamentally a slightly convex midsole shape that inspires the runner to land on the midfoot rather than the heel. Such action aims to mitigate the impact and cause speedier transitions through the gait cycle. Other conventional design elements such as an uncluttered façade and responsive underfoot experience help to better the performance.

Mizuno Wave Rider 22

The Wave Rider is one of Mizuno’s most enduring series. It has taken over 20 forms, evolving with the times and providing some of the most reliable products in the market. The purpose of the Rider products is precise yet straightforward: offer a robust and comfortable running experience that feels consistent, even after long miles.  It features a bevy of technologies in the midsole like the full-length U4ic and the U4icX heel piece for well-rounded cushioning, as well as the thermoplastic Cloudwave layer that offers extra bounce and shock-attenuation. On the upper of the Mizuno Wave Ride 22 are the engineered mesh and Dynamotion Fit, stretchy and non-irritating elements that secure the foot and keep it in place.

Under Armour Dash RN 2

The Dash RN 2 from Under Armour is an entry-level road shoe that caters to those on a budget and those who still desire sporty shoe-façades and highly functional features. This shoe is lightweight and straightforward in its purpose. It has a cushioned foam midsole, a traction-ready outsole layer, and a ventilated upper that’s supported by stitched overlays. Some said that the silhouette of the Dash RN 2 is a throwback to early models of running shoes, the ones that date back to the early 2000s. Still, it’s considered as one of the most accessible models in the Under Armour stable, offering just the right performance for neophyte runners and exercise fans.
