adidas Ultra Boost Uncaged Performance Review

Ultra Boost has always been popular, and both runners and shoe fans have consistently promoted this fashion running shoe. At the end of last year, after adidas launched Uncaged Ultra Boost, it was simply subverting the whole wave of shoes. Everyone rushed to buy, and some people even spend more higher price to get one .Adidas knows the passionate love of the fans for the “Umtra Boost” and decided to officially launched the first pair of Ultra Boost Uncaged series, which wind a  trend of the “walking” .

But what is it  like ? How does this shoe  performance? Here we will check it .

Ultra Boost Uncaged  featuring a fall-ready blend of dark burgundy and black across the shoe’s usual Primeknit upper with the heel counter in a textured matte black finish.


The Uncaged series of shoes combines functionality and style with Primeknit weaving technology to create a breathable and comfortable wearing experience with a clean, sleek look. Compared to the original Ultra Boost, the Uncaged series features a flexible sock-style design that perfectly encases the ankle and enhances flexibility. Adidas also abandoned the  plastic cage with three strip on both sides of the shoe .


For the supporting :

The most obvious is that the outside is obviously thinner than the inside. In fact, the reason why is because during the running process,  most people are touching on the ground outside of the foot when you walking . The heel wear of the shoes if you look your shoes’s traction. Generally,the out side of midsole  will be wear easily compare with the inside midsole. For running shoes, if the heels are flat on both sides,then it is easy to twist the ankle after rebounding, so it is easy to twist the outside.

So one version of the Utra Boost  used the plastic torsion syatem to provide the stability .

The inner surface is covered with a high density eva material. Both played a good role to avoid the torsion .

The main role of this overhanging  of outsole. that is  to protect the heel material avoid the wear and tear . As mentioned above, most people use the outside foot to touch the ground.Then we tested it as below :

Before touching the ground:

Touching the ground:

After touching the ground.

So we can see the proceed of touching the ground as above , our heel part also have been protected when we touching .


Because boost stability is poor, adidas designed a stereo stabilizer for the Ultra Boost  .The  Torsion system  lies in a recessed cavity, it’s funnel shaped ends spreading up and outwards from there. Also it will provide the superior heel to forefoot stability.

The forefoot does not have the stability  without the torsion system, it seems very soft. But the back part of the torsion system remained in a straight state after I pressed it hard.



For the traction : The traction with a single piece of soft rubber with rectangular perforations exposing the Boost midsole. This the  most important is the different  compare with the tradition ultra boost.


For the material : 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.

And different weaving methods are used in different parts. For example, the thumb and the toe area are encrypted and thickened which  make it more durable. but the for the part of  instep and the arch, it is use the special weaves to keep the good ventilation.In order to Keep your shoes dry. it is used the heat welded fuse on both sides of the toe and upper. Not only enhances the protection, but also makes the shoes look more straight.

So we can see more details and tested  as below :

Your big toe being pressed down by the Primeknit upper, though visually it looks like there’s plenty of space ahead of your toes. 

Overall,this pair of shoes is in terms of design and performance. The positioning of its trend running shoes is great.Anyone would expect a truly exceptional product under the circumstances, and we feel that the Ultra Boost Uncaged   still has some ground to cover before it can honestly be called great.

adidas Ultra Boost Uncaged Performance Review

It’s not hard to see why the Adidas UltraBoost is such a popular shoe since the adidas Ultra Boost Uncaged joined  its caged brother in helping to celebrate the Chinese New Year in the near future.

What do you think of the upcoming adidas Ultra Boost Uncaged Chinese New Year?So we will look it  closely today.

For the box ,it is simply.

However, the side look cool.The front of the shoe box is printed with CNY—China Year. Not the same as a regular yellow striped box. In contrast, cny this shoe box design is more low profile

The Primeknit and Boost combination takes a simple approach this year, as a white knit upper sees speckles of black and red throughout for a random array of swirls to compliment the unique lace option .

Adidas’s claim that the UltraBoost will deliver “your greatest run ever” is hard to prove, I felt that is the setting win a lot of buyer, especial for runner,the  UltraBoost, it became my go-to shoe for long distances.

For the material : It used the  Primeknit  again .As we know this kind of material is great. Midfoot partially switches to another material, and so does the heel area.Like engineered meshes, the single piece Primeknit has multiple zones of stretch.  So you can feel more elastic in places like the top of forefoot, while the edges and toe bumper have a closed knit construction for better structural support. but only one disadvantage of this kind of material , it will be easy to break out .

Then the ventilation , it is great, we can feel the air through the foot . and the special lace system.I can adjust it easily.

We can see more details as below :

Adidas Ultra Boost series were impressed with Adidas tech,which new model and its springy, lightweight protection from harsh pavement. “This may be my new favorite shoe,” tester Derek Call raved. “Some backstory: The Adidas Supernova Boost 6 was one of my favorite shoes of all time. It took three years for me to find a shoe even comparable to it, and that was last year’s Adidas Supernova.but this one adidas Ultra Boost Uncaged will be better , that is for me, it was an improvement on that shoe. It feels lighter, my foot slips right into the upper like a slipper, and it still offers enough stability without adding any weight or material

The insole look great.Also it is comfortable .

We can see more details inside.

Midfoot cage attaches to the molded heel clip with an inwards flare. Also it show the ULTRA BOOST which  uses so much plastic on what could have been a lightweight upper with unadulterated stretch.

Solar Boost offers fantastic traction for a road shoe,  so you can feel more comfortable and soft when you playing .even on snowy or slushy roads. That is why the small lugs on the full-length rubber outsole provide plenty of grip on and off pavement, while a wide heel gives the shoes a planted feel.

Overall, a Boost running shoe needs to feature at least one of the stability elements. Either a plastic cage with midsole ridging , so the adidas Ultra Boost Uncaged did it , the nice cushion midsole and great material ,also the  soft traction , all of the reason to attracted  more people.
