Nike Kyrie 7 Performance Review

We have deconstructed the Kyrie 7 and share the technical information of Kyrie 7. Today, we want to share the performance review of Kyrie 7 with you.

Suited Court: indoor court or outdoor plastic court

Suited Players: The defenders whose weight below 85kg.

Suited Foot type: normal size, if your instep is high, it’s better to have a try before purchasing.


Will the lighter vamp effect the strength? The answer is not.

Comparing with Kyrie 6, Kyrie 7 don’t use the leather and Velcro. But the 3 layers of composite vamp can offer good supporting performance. We can feel the tenacity of vamp when making lateral movement.

It can satisfy the request of Kyrie.

Meanwhile, the green stiff material is link of insole and outsole. It increases the supporting performance of vamp.

It’s surprised the design of dynamic shoelaces. After fastening the shoelaces, it will fix the forefoot well.


Although it still uses the same Air Zoom Turbo and full-length Phylon, but it still has big difference with Kyrie 5 and Kyrie 6.

The feedback of air cushion is more obvious. I can feel the feedback of air cushion obviously when putting on Kyrie 7. It doesn’t need time to break-in.

The more important part is the low center of gravity.

It not only has excellent feedback and it reduces the center of gravity.

The rear sole still uses Phylon. It’s not stiff. The cushion performance is enough for me. But it’s better not choose it if your weight is over 85kg.


Many guys doubt the abrasive resistance of Kyrie 7.

I can’t offer the exact judgement for the abrasive resistance of Kyrie 7 now. As I only play 5 basketball games till now. I haven’t found the abrasion on the outsole. And the depth of outsole is thick.

The traction performance of Kyrie 7 is reliable. It can grip the ground well.


The anti-rollover performance of Kyrie 7 is improved. As it has low center of gravity, the forefoot sole doesn’t have anti-rollover design. But it’s more stable than Kyrie 5 and Kyrie 6. It can satisfy the multi-directional traction performance.

The rear outsole is wider.

Kyrie 7 don’t have built-in arch supporting plate, the internal support is not good enough. If it has a extending stiff material from the arch part like Kyrie Low 2, the anti-torsion performance will be better. If you want to play high-strength basketball games, it’s better to put an arch supporting shoe-pad in it.


Fitness of vamp: 9

Supporting performance of vamp: 8.5

Feedback of forefoot sole: 8.5

Cushion performance of rear sole: 7

Anti-torsion performance: 6

Anti-rollover performance: 8

Traction performance: 9.5

Overall Protection: 8.5

Overall supporting performance: 8.5

Overall stability: 8.5

Overall scores: 82

Overall, comparing with Kyrie 6, Kyrie 7 is a pair of shoes which is lighter, has lower center of gravity, better cushion performance and better stability, but the ani-torsion performance is reduced.

For defenders, Kyrie 7 maybe not the best choice of basketball shoes, but it’s still worthy for you to consider it.

Insole: The AIR STROBEL cushion brings excellent feedback. The big TPU supporting plate improves the stability of insole.

Overall: PG 5 still uses the AIR STROBEL cushion as the insole technology. By adjusting the material of vamp and insole, the fitness, stability and comfort level have been improved. But the appearance is not attractive.

Adidas Ultra Boost 21 Performance Review

The Adidas Ultra Boost has updated 10 generations. It’s popular on the market. Since Adidas paid to Kanye West to wear the white UltraBoost 1 on the stage. Many people start to wear Ultra Boost as casual shoes. Ultra Boost can be professional sneakers and casual shoes.

Is the new released UltraBoost 21 the sneaker or fashion casual shoes? Or does it have both functions?


We can see the thick Boost insole after unboxing. The tail is upturned.

The shoe tongue is integrated design. It doesn’t need to worry that the shoe tongue will move when running.

Due to the integrated shoe tongue, the shoelaces need extra support to be fixed. The transparent TPU adidas logo improve the supporting performance.

The extending shoe heel is convenient for putting on and taking off.


Adidas Ultra Boost 21 uses Primeknit technology. The fitness and supporting performance of Primeknit material is good. It also has good air permeability.

The vamp and shoe-pad uses Primeblue materail. Primeblue is made of Parley ocean plastic. It’s a kind of recycling environmental protection material.

The unit weight of EUR40 is 309g. It’s not light. As the target location of Adidas Ultra Boost 21 is not racing. It’s suitable for jogging.

The drop height of forefoot sole and rear sole is 10mm. The height of forefoot sole is 20.5mm, and the height of rear sole is 30.5mm.

The drop height of Adidas Ultra Boost 21 is high. Normally the drop height of racing shoes should below 5mm. But the high Boost of rear sole can absorb the impact force. It’s suitable for the beginners.

Boost Insole:

As the official said, the insole material of Adidas Ultra Boost 21 is increased 6% than last generation. The 6% is the result after trail and error. So we can see that the insole of Adidas Ultra Boost 21 is thicker.


The Adidas Ultra Boost 21 uses Continental Stretchweb outsole. There is a big area of semi-transparent rubber.

The characteristics of this kind of outsole is the noise when running.

Another core upgrade is the new Adidas LEP(Linear Energy Push) system. Comparing with normal lacing system, it increases about 15% bending rigidity of forefoot. This kind of design is beneficial to running.


Court: Plastic track and road.

Speed: 4’30

Distance: 15km

The sole is very soft when running in soft plastic track. It’s very comfortable. It’s not too soft and not too stiff when running in stiff road.

For me, Adidas Ultra Boost 21 is comfortable when running at the speed 4’30.


The insole of Adidas Ultra Boost 21 is thickened. It improve the hardness. With LEP system, Adidas Ultra Boost 21 is more suitable for running.

With the wide outsole, thick Boost insole and the reinforced frame,  Adidas Ultra Boost 21 is suitable for the runners with heavy weight.

If you want to choose a pair of running shoes for aerobic pace training, you can choose Adidas Ultra Boost 21.

Adidas Ultra Boost 21 has 24 colorways. You can find your favorite colorways.  Adidas Ultra Boost 21 is not only a pair of sneaker, but also a pair of fashion casual shoes.
