Our verdict

In the realm of running shoes, we've found that the Adidas Ultraboost holds its own crown as a bestseller, despite its steep £180 price tag. It excels in breathability, outsole durability, and above all, its versatility as a fashionable-and-cosy everyday sneaker. However, despite its widespread popularity, we noticed that the shoe listn't mask its flaws when it comes to running—it's simply too heavy and the Boost foam felt boring in all of our test runs.

Who should buy

In our opinion, the Adidas Ultraboost is an ideal choice if:

  • You're seeking a breathable shoe that can double as a magnificent casual sneaker.
  • You desire a durable daily trainer and the extra weight is not an issue.
  • The £180 price tag is not a problem.

Who should NOT buy

We've concluded that for dedicated runners clocking high mileage, the Ultraboost may not meet contemporary expectations for a high-performance running shoe. In our experience, it's too heavy, lacks energy return, and we think it's priced excessively for the value it offers.

If you want a modern-day, cloud-like daily trainer, we recommend considering options like such as the Nike Invincible 3, adidas beckenbauer vapour grey pants images of adidas coolmax shoes clearance boots with its ultra-cushioned FF Blast+ foam.

Lastly, if you're a forefoot striker, the Ultraboost might not be your best choice. We suggest you consider the New Balance Fresh Foam X More v4 instead.

Cushioning

Heel stack

With a generous 34.4 mm of height, this shoe is certainly a top pick for heel strikers. In fact, it's this feature that has made it a crowd favourite across all the Ultraboost editions.

It's worth player that our measurement exceeded Adidas's official 22mm mark by over 12mm, which is insane. This discrepancy is due to the Ultraboost's initial launch before the World Athletics guidelines for measuring drop—which we adhere to strictly in the lab.

These guidelines stipulate that stack height should be measured inclusive of the insole and outsole and on the same point in every shoe. Adidas, however, measured only the foam and used a different reference point.

Forefoot stack

On the other hand, for those of us who predominantly strike with the midfoot or forefoot when running, this might not be a top adidas tumblr shoes beige blue grey despite its £180 price tag.

The calliper-based measurement comes in at just over 20.2 mm, which, to be frank, feels really low. It's a big head-scratcher, especially considering that this shoe is often marketed as a go-to for long-distance running. No way, Adidas!

Drop

Both measurements translate to a staggering 14.2-mm heel-to-toe drop, a jaw-dropping result that counts among the steepest we've ever logged in our lab.

It's fantastic news for heel strikers. However, it's an awful drop for those who tend to be midfoot or forefoot strikers. And it's too far away from the official 10-mm drop stated by Adidas.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Now, let's talk Boost. Back in 2013, this TPU-based foam took the world by storm with its springiness and dreamy soft feel, as we explained in our advanced guide about foams. And it delivered world records in long distance running.

Yet, a decade later, it's evident that while it's fine for walking or the occasional jog, it listn't quite make the cut for serious runners.

adidas ultraboost foam 20014029 main

With the advent of superfoams such as ZoomX and Lightstrike Pro, Boost now feels a bit old fashioned. But let's not overlook its durability and its excellent performance for walking and light jogging. That makes it a top-notch shoe for casual runners.

We recorded a measurement of 19.9 HA, indicating that it's softer than your average foam. Yet, we noticed that this plush sensation is more evident during a walk. When you pick up the pace to run, the foam feels a tad firmer than expected, although it's not firm by any means.

Midsole softness in cold (%)

With a measurement of 22.9 HA, the midsole retains a balanced feel in cold temperatures. It's neither too plush nor too firm.

Although Boost might appear a bit dated, its performance in chilly temperatures remains exceptional.

It hardens by only 15.1% in the cold—a result far superior to the average increase of 26.9%. This characteristic ensures an excellent run even in the coldest days of the year.

Toebox width - widest part

We measured the upper at its widest part, registering a narrower-than-average result: 95.9 mm.

However, here's a crucial point here: the Ultraboost's Primeknit upper is known for its super-stretchy nature, which we showcase in the video below.

After hitting the roads or just walking around in these shoes a few times, we found them really spacious.

Stability

adidas beckenbauer vapour grey pants | Lateral stability test

Having put the Ultraboost through proper testing, we can't exactly tag it as a "stable" shoe. Still, the plastic-made three-striped midfoot cage—which doubles as a lacing cage—and the heel clip do give neutral runners equal stability.

However, if you're someone who needs a more substantial stability feature, it's worth looking into options like the Brooks Adrenaline GTS 22 or the adidas coleahs black dress women.

Torsional rigidity

The Ultraboost exhibits flexibility akin to a yoga teacher. That's a score of 1 out of 5 on our scale!

We're pretty sure that this shoe's is one of the less rigid we've ever tested. And that's a major reason why we grab it for all-day walking and slow runs.

Heel counter stiffness

The Ultraboost listn't have a traditional heel counter, and this was one of the main innovations that Adidas brought to the table with the original model. Instead, it features two plastic pieces that give the heel some lateral support, and these are what make the heel moderately stiff. 

We rated it at 3/5, slightly stiffer than the average, and we're happy to report that we didn't experience any heel slippage, which was a pleasant surprise given the limited lacing options of this shoe.

Midsole width - forefoot

With a forefoot width of 107.3 mm, it's clear—one more time—that Adidas has designed this shoe primarily for heel strikers, overlooking the needs of other runners.

Weight

Weighing in at 11.3 oz (320g), the Ultraboost 1.0 is substantially heavier than the average running shoe. It's a glaring issue in today's world where lightweight footwear is the norm. For instance, another best-seller workhorse like the ASICS Novablast 3 weighs 8.5 oz (242g) and it has a higher stack height.

In summary, while we appreciate the durability and comfort of Boost foam, we can't ignore its tremendous weight. This likely prompted Adidas to introduce the new Ultraboost Light, nmd r1 peach salmon adidas black friday 2020.

Breathability

The Ultraboost truly SHINES in breathability, leading the pack with its super-quick smoke expulsion.

We can count on one hand the shoes that outperformed this one in our breathability testing machine, earning it a solid 5/5 rating.

But, what's the secret behind its breathability wizardry? It all comes down to Adidas's smart design of their Primeknit upper. It sports oversized ventilation holes in the toebox and midfoot, which are clearly visible in our light test.

Finally, we turned to our microscope to get a detailed look at those ventilation holes. It reveals a fairly-dense knit pattern interwoven with these larger airflow perforations, working in harmony to achieve perfect breathability.

Durability

Toebox durability

Knit uppers usually come with a trade-off: comfort for durability. The Ultraboost falls into this trap, being unbelievably comfortable yet incredibly fragile.

So it didn't shock us when our standardised Dremel test left the upper destroyed in no time flat and forced us to gave the shoe a 1 out of 5 in this test.

It's just the price you need to pay for its cozyness, and if you tend to wear holes in your shoes with your big toe or pinky toe, you may want to try the Ultraboost 22 or the On Cloudswift 3 yeezy powerphase grey australia blue bottle price.

Outsole hardness

A key contributor to the Ultraboost's immense popularity is its legendary Continental outsole. Our measurements placed its outsole hardness at 86.1 HC, which is notably above average.

Removable insole

Swapping out the insoles in the Ultraboost is quite a common practice in the sneaker world. And here's a handy tip we can share: if you feel the shoe listn't offer as much volume as you'd need, you have a couple of options:

  1. If you're using the shoe solely for casual wear, you can try to remove the insole and see if it feels good.
  2. If you plan to run in them, consider swapping the original insole for a thinner one. This can give you those few extra millimetres you're after.
