Tag: Adidas Ultra Boost 4.0 Performance Review

As we know the set of 5Ks that empowers running communities to combat the extreme amount of marine plastic pollution in today’s world , so the Deep Ocean Blue” Parley Ultra Boost 4.0 was the official shoe which inspired by the deepest part of the world’s oceans –Mariana Trench.  but I just got the black one.And we will test it today .

The shoe’s unique Primeknit upper is offset by a black plastic midfoot cage, and the tongue features black adidas and Parley branding.

Whether  it is as a professional runners shoes or the casual shoes, there are more topics for this running shoe.and a lot of people will buy and test this shoes .

Unlike the Ultra Boost ST which prefers the reinforced the supporting , and it also differs from the Uncaged which only  focusing the Primeknit uppers. The Ultra Boost 4.0 was more profession with  perfect Primeknit uppers together.As for Energy Boost 4, I think it is a bit of out of fashion with  Tech-Fit upper and EVA and Boost midsole.seems theEnergy Boost 4 like a pair of traditional running shoes?

 

The soft and comfortable Primeknit knitted upper, and the plastic counter also cups under the heel edges,and the famous full length  Boost cushioning. The classic Torsion System midsole and the Strech Web  rubber outsole constitute the entire technology of the Ultra Boost 4.0.

Here’s our take on why the Ultra Boost uses so much plastic on what could have been a lightweight upper with unadulterated stretch. We think that the Boost midsole is inherently unstable once the foam volume crosses a certain threshold, and that is why adidas uses one of the two things – a plastic midfoot and/or a midsole rim.

 

Perhaps Utra Boost 1.0’s design has been classic one, or the appearance of running shoes has been accepted by consumers, so the  Uta Boost 4.0 is only a slight adjustment on the upper material and the traction, we will check it closely .

 

The Ultra Boost upper isn’t pure Primeknit, but rather a hybrid which uses elastic-knit in forefoot and midfoot, and a bootie construction in the rear which relies on traditional stretch fabrics.

Midfoot cage attaches to the molded heel clip with an inwards flare. This plastic counter also cups under the heel edges.

While we generally see a flat piece glued flush with the outsole, the footbridge here originates in a midsole cavity.

The side support and the Primeknit uppers are visually more low-key coordinated. Compared to the Utra Boost 3.0 translucent material looks more stable and strong.

There are the BOOST  symbol inside of shoes.

For the traction :just a single latticed sheet clothes the bottom. The exposed windows help reduce weight and increases the ride softness and consistency. and the traction improved the grip and stability compare with last version .

The other side of the compression molded EVA midsole. The last markings indicate a different base fit than other Boost models.The Energy Boost and Glide Boost all are based on different upper fit dimensions

The classic Torsion System is firmly embedded in the midsole of the running shoe, extending from the forefoot to the back.
It can be seen that the HeelCounter heel locking system was extending to the heel ,high-density Boost and Torsion System anti-twist system are all constitutes the running shoes, making the running shoes practical in the short distances.

adidas calls its outsole design ‘Sprintweb’, a single piece of soft rubber with rectangular perforations exposing the Boost midsole.

A white Boost midsole provides contrast and comfort, and the shoe is rounded off with the Ultra Boost’s standard Continental rubber outsole for exceptional durability.

There are more picture on-foot as below ;

 

Running (5-10km and sprint), but also sports like fitness, or some recreational sports.
I can run from 0 to 2-3 times a week, it depends on the period, but I’ll use it also for some sport and when I’ll walk a lot.

I’m also looking for a shoe which is very comfortable, flexible, responsive, with good transition and and ventilation and beautiful

The most intuitive feeling  is the comfortable fit . Compared to Nike’s Flyknit, Primeknit is more conformable , and excellent stretchability gives better tension to the upper. After solving the problem of previous uppers, the Primeknit upper will maximize .Then it fit with all types of foot.

It can be seen that the full length Boost cushioning effect is obvious, and the shoes will be fact more   impaction when running.

We have to remember that the Ultra Boost is very much a neutral shoe, and the midsole behavior is well within the boundaries of that.  then transition quality which feels great for a shoe this cushioned.

Different Primeknit knitted and different densities of material will bring the different wrapping under different situation. The HeelCounter  locking system also did a great job ,but sometimes it will give more pressure to ankle .

 

The heel softness is comparable to the Energy Boost 2 , but with one major difference , the midsole of UtrA Boost  is far more responsive.  If you were to look at the midsole heel top down, you will notice that a good portion of the Boost foam sticks outwards, along with the outsole lip.

Here are some gif picture as below :

The Ultra Boost is that the front and rear part of the midsole work together as two separate halves. In the back, a very cushioned ride pampers your heel as explained in the cushioning breakout.

A squashy toe-box and the unwanted pressure from the midfoot cage make a dent in the German brand’s ‘greatest running shoe’ claim.

Overall, I try to test nay angle , the traction is amazing with nice responsive. And the full length Boost ,it  will bring the great bounce and the TPU with the Torsion System also did a great job.

 

 

As the Ultra Boost 4.0 has been released ,it is updating  from the  Boost 3.0.Compare with last version ,whats updating ?

We will check it today.

Featuring an upper woven with black plastic material, the shoe offers a unique striped black look that provides a striking contrast with the black plastic midfoot and heel cage. Black laces with an abstract pattern add an extra pop of detail, seems nice and matched .

Unlike the Ultra Boost ST, it prefers the reinforced support on the inner side of the running shoes, and it also differs from the Uncaged which only retaining the Primeknit uppers. As for Energy Boost 4, the old model— Tech-Fit’s upper are with EVA and Boost midsole. Isn’t this like the  traditional running shoes?

The soft and comfortable Primeknit knitted upper, the plastic strip and HeelCounter heel locking system, and the famous full- Boost cushioning. full-length white Boost midsole  and the Strech Web mesh rubber outsole  technology ,all of are make the Ultra Boost 4.0.

There are more details as below :

 

The updated sole consists of a stretchy rubber in an open grid pattern that adapts to your foot’s movement and makes for a smoother transition from heel-strike to toe-off.

The toe is angled up higher, which further helps the shoe roll. Some runners may find the rigid plastic overlays around the heel and arch uncomfortable, but if the shoe fits, get ready for an ultracushioned, responsive ride. 

The mega pull tab is a visual oddity yet functionally effective, and comes in very handy when putting the shoe on. 

For the material : We were always curious to find out how adidas Primeknit compares against Nike’s version, which by the way, comes in different iterations. Like the super compressive Nike 3.0 Flyknit, or the more easy going version on the Flyknit Lunar. For now, we can only judge Primeknit based on its use in the Ultra Boost, but as time goes by, we should be exposed to more variants.it feels more elastic in places like the top of forefoot, while the edges and toe bumper have a closed knit construction for better structural support.

For the ventilation :it is nice , the forefoot top is more porous and breathable, which also makes it more accommodating to stretching.

The energy-returning boost™ technology was welcomed by many runners because, for them, it was able to deliver responsive underfoot cushioning

For the lace system : it is easy to adjust the shoes when you running .

It is show the boost  symbol, the sole actual court feeling is amazing

 

For the traction : not many pieces of rubber here, just a single latticed sheet clothes the bottom. The exposed windows help reduce weight and increases the ride softness and consistency.

 

The classic Torsion System is firmly embedded in the midsole of the running shoe, extending from the forefoot to the back.Then the strip surround the HeelCounter heel locking system , and the high-density Boost and Torsion System anti-roll system are making the 4.0 ,also this setting up will be great for the runner .

The external heel counter was lauded by a user because it kept their heel in place and prevented it from wobbling or accidentally exiting the shoe

On some level, the Ultra Boost is similar to the Energy Boost 2. The two models can be compared on shared traits like a compressive upper, plastic midfoot cage and heel, and a prodigious chunk of exposed midsole hewn out of bouncy Boost foam. Even the plastic ‘Torsion’ shank dams up on the Ultra Boost’s medial heel the same way the EB-2 does. At the same time, the two differ on the quality of fit and cushioning behavior, and as always, we’ll talk about it at length before the sun goes down.

As a fashion sneakers, the fashion design is important. From the perspective of appearance, Ultra Boost 4.0 was followed the last model . but the the shoes look more smoothly and naturally, taking into account parcels and fashion trends.

We  can see more details as below : 

This plastic counter also cups under the heel edges. Leaving the Achilles area free was smart design thinking

For the cushioning test : the cushioning is amazing ,  The heel softness is comparable to the Energy Boost 3 , but with one major difference – the midsole is far more responsive. That is caused by two factors. If you were to look at the midsole heel top down, you will notice that a good portion of the Boost foam sticks outwards, along with the outsole lip.

 

The outsole rubber extends slightly outwards to provide protection , and the curved upsole structure on both ends allows for smooth transitions in the  responsive  foot. It can be seen that the full-length  Boost cushioning effect is obviously, and the heel impact is maximized when the heel strikes.

We can see the GIF picture as below :

The effect which has the narrower foam sink in and come back out soon after weight moves forward.Then a wider flare on lower midsole creates a greater contrast with the upper portion, which then becomes relatively narrower.

Overall : After having looked at the Ultra Boost from multiple wear-test angles, we know the shoe has many things working for it, the nice boost tech and the great material,an upper fit which feels snug yet comfortable, and transition quality which feels great for a shoe this cushioned. But for the supporting , it is not enough as  usually . So how  about you think ?
