    Adidas Ultra Boost: Is it worth the purchase?

    Adidas Ultra Boost was first released in 2015 and acquired significant good reviews and comments both on the internet and from close friends.

    That intrigued me to try it out.


    Appearance & Color Variation

    As of now, I believe they have more than 30 color variations.

    I choose the standard black for no particular reason, just maybe because after a while the dirt is less shown on the fabric.

    In my opinion, Adidas could have worked harder on the appearance, as you can see it's just plain black throughout the entire shoe and the sides as well. I would prefer to have other colors on the side and back of the shoe for instance.


    Comfortability & Upper

    When you wear the Ultra Boost, you feel your feet is wearing a sock as the Primeknit make the fabric really soft and comfortable.

    On the upper part, you can feel no manufacturing seam, and despite my concern on the first days, it is very well built.

    As you can see below, after several months of usage it is still in good shape, it's just like new.



    In terms of ventilation, it is also good and this new Adidas technology gives a smooth step feeling not only to the upper part but to the feet as a whole.

    In terms of weight, it is also remarkably light for the amount of cushion it posses.

    Running (Cushion, Stability & Sole)

    As just said before, even though its lightweight, Ultra Boost provides a good amount of cushion, giving a smooth ride to the runner.

    However, and this is very important for me and all the runners with ankles issue, the stability on the Ultra Boost is not good at all, and you can easily twist ankle and foot while running.

    I tried to simulate on the photo below what happened to me a couple of times.



    I believe this happens because there is no structured support that wraps up the ankle where they applied the same fabric as the rest of the shoe. This makes the ankle area very smooth as the rest of the shoe.

    For that, I give a strong minus.

    For the sole, it is good for different types of soils and more importantly, durable. The grip is also very good but just not in line with the stability needed.



    As you can see, even after all these months, it looks just like new throughout the shoe.

    The only thing that I disliked here is what I highlighted In the photo above, the excess of the sole on the back part which is longer than the foot itself.

    It made the shoe just ugly, but I believe its objective is exactly to make the sole more durable. Anyways, my comment is noted.

    For the back part, I was disappointed with the lack of reflective light in order to provide a safe ride for night runners.


    The Day After

    Before reviewing shoes, I always like to wait for the day after to completely evaluate it not only during the exercise but also its effect on my body after it.

    And with Ultra Boost I got just what I expected. Very few leg sores due to its good cushioning system, but quite significant amount of pain around the ankle.

    From the photo below you can see how lacking the support around the ankle is in comparison to similar premium shoes.



    On the left part from the photo above, you can even see how the shoe lost its format around the ankle, which is very disappointing for the price you pay for.


    • Durable well-built shoe with good upper support and high-quality materials
    • Great energy returns while running, improving overall running experience


    • High price tag
    • Bad stability despite the amount of cushion it provides
    • Bad support around the ankle
    • Lack of retroreflective light on the back part for night practices


    The Adidas Ultra Boost is indeed a new era for the cushioned shoes because of its soft solid fabric, weight, and comfortability.

    It is a very flexible shoe with good responsiveness during exercises and even after several months it still looks just like new. It's also a very well built and durable shoe.

    However, it lacks good stability and support around the ankle, so if you have ankle issues it is not recommended for you, or if you are planning to use it on uneven terrains.

    In other words, its best fit for treadmills, but then again, is it worth the price you pay? You tell me.

    Adidas Ultra Boost – Comfortable runner or confused slipper

    I heard about the Ultra Boost from a mate, he told me that nothing can compare to the comfort you get from the Adidas Ultra Boost. I decided that I had to get a pair in order to cure my curiosity.

    At first glance, the Ultra Boost seems to break all the norms. The upper is made of a knitted like material the midsole looks like polystyrene balls glued together. It really had my curiosity going and I could not wait to get my feet into them. Yes, it had the looks, the bounce, and comfort like a slipper.

    Now for the true test, is it a running shoe or just a comfortable slipper?


    Midsole & Outsole

    The midsole is comprised of full Adidas Boost material from hill to toe. The outsole is Continental rubber which this model calls stretch web.

    Midsole has a bouncy effect. When you first place the shoe on and start jumping on the spot, you get a good feel of comfort and cushioning.

    The profile of the midsole is rather flat when on your feet as there is not much structure to support the mid and front foot. This does not make it a contender for a good racing shoe nor does it have enough structure for a marathon shoe.

    Outsole has the Continental logo branded into the rubber. My first run in the Ultra Boost was 21km on asphalt. I expected a tough outsole – however, there was excessive wear by comparison to my Supernova Glide Boost. The stretch web outsole smoothed out quite quickly and you're basically left with a slick punched sole.



    Often the words referred to is sock-like; here the appropriate metaphor would be “slipper-like”. The Primeknit upper is nothing short of comfort. Upper at the toe box area has a stretch knitted material that is airy and comfortable.

    There is no tongue, which has the disadvantage of not having enough padding between the foot and laces. The laces can be felt on the bridge of the foot, if too tight.

    The plastic cage keeps the foot locked down without a slide. The cage is made of a thick plastic and contradicts the whole concept of breathability and comfort.

    I feel that the cage structure could have been made from a cloth material rather than plastic, Nike uses thin “flywire” -  Adidas could have been a little more innovative with the lockdown system.

    I do like the idea of the external hill support with the split, combined with an extra overhang of the Achilles' lip, making foot insertion really easy. In fact, I barely do my shoelaces with the Ultra boost, it slips on and off.


    • Comfortable
    • Bouncy boost midsole
    • Easy slide on and off – slipper like


    • High Price
    • Outsole not durable
    • Plastic cage could be softer/breathable
    • Laces can be felt on the bridge of the foot


    The Ultra Boost is a comfortable shoe; the primeknit upper hugs your foot without any constraint. Your feet have a true sense of freedom, comfort and loads of breathability. The bouncy boost midsole offers plenty spring under your foot when running.

    The excessive wear on the outsoles is disappointing to me, especially when one considers the price; I expected a lot more mileage before seeing such wear.

    The Ultra Boost for me makes an ideal treadmill shoe, the soft outsole takes away that “clanky” sound at impact you normally get from a tough carbon outsole.

    The outsole with the extra overbite at the hill makes for a good hill strike on the treadmill. I have seen this on trail shoes, but not really on road shoes.



    In conclusion, I have found a place for the Ultra Boost and that it is destined for a life on the treadmill. That is not necessary a bad thing or a bad buy from my part, it, therefore, fits into a niche part of my shoe cupboard. I have done 200km on the treadmill with the Ultra Boost and will continue to use it for that purpose.

    Now if you don’t own or have access to a treadmill, the Ultra Boost makes great slippers.

    My Thoughts on Adidas Ultra Boost V2.0

    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.



    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.



    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.



    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.



    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.


    • 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


    • 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


    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.

    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.

Updates to Adidas Ultra Boost

  • Adidas hypes the Adidas Ultra Boost as “the best running shoe ever.” Such 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 Ultra Boost boasts of ¾ one-piece Primeknit upper that hugs the foot in comfort. A Stretch Web 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 pressure off of the Achilles.

Adidas Ultra Boost size and fit

The fit of the Ultra Boost 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. Sizing is on cue in this shoe as well. Sizes are from 6 to 15 for the men’s and 5 to 12 for the women’s.


The outsole literally resembles the form of a as it is rightfully called the Stretch Web. 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 Ultra Boost has an astounding 20% more of these shock-absorbing and responsive 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. 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.
