When talking about insole technology, people will think about Adidas Boost technology. Today, we want to talk about the performance of Adidas Ultra BOOST 19.
From Ultra BOOST 2.0 to Ultra BOOST 4.0, most of people can’t distinguish their difference. But most of people think that it’s a pair of great running shoes. And now Adidas Ultra Boost 19 has made the revolutionary improvement in several parts.
The shoebox is with yellow, white and purple. It’s printed with a big “BOOST”.
It still uses flat type vamp with crooked shoe shape. It has high height difference of forefoot and heelpiece.
We can see the Boost on heelpiece is thicker. The official said that it adds 20% of insole Boost. The main colors are red, navy blue and creamy white.
It uses Primeknit 360 one-piece knitted vamp. Both side of the knitted vamp is black, and the middle part is white. It inserts red knitted wire in the instep.
The classical three-wire TPU of UltraBoost has been changed to high-intensitive gauze element. The advantage is to improve the wrapping performance and comfort level.
The integrated shoe tongue is seamed with Adidas logo. The shoelaces are flat type. The holes of shoelaces are also flat type.
It uses 3D Heel Frame design on heelpiece. It can reduce the weight and keep the stability of heelpiece. The 3D Heel Frame is made of transparent part and red part. The integral shape is modern. The stiff part on 3D Heel Frame can reinforce the stationarity of heelpiece.
There are two pieces of sponge on the shoe mouth. The vamp is red and printed with “BOOST”. The integrated knitted vamp of Primeknit 360 make the Ultra Boost 19 to be socks.
As it increases 20% of Boost material in insole, so the insole looks very thick. And the particles of Boost is unordered, and it doesn’t have punching holes.
The outsole still uses Continental rubber. From the outsole, we can see the Torsion Spring anti-torsion system in the insole. Due to the Torsion Spring anti-torsion system, the anti-torsion is excellent.
It’s easy to wear. Although the half sole is thin, but we can obviously feel the cushion on heelpiece.
The shoes fit well with the foot, and the toes have space for moving. The tenacity of knitted material on vamp is not enough, but it has the elasticity. The stability of the shoes can satisfy the requirements of slower running. I’m satisfied at the heelpiece part, which is very soft and fit well with the foot.
The heelpiece of insole is very high, the thickest part is about 4cm. But we don’t feel that the center of gravity is not stable. It’s because that the area of outsole is big and incline to the two sides. Pressing hard on the heelpiece, we can feel the cushion from the thick Boost. The cushion and feedback of Ultra Boost 19’s insole should be more lasting than other Boost sneakers when running.
When jumping and jogging, I can also feel the cushion from half sole. Although it’s not strong, but the soft feeling is exactly existing.
I have ran on the road by Ultra Boost 19 after raining. The Continental rubber outsole haven’t let me down. The traction performance is great. As I only weared it for testing only about 3 days, so I can’t confirm the abrasive resistance of the outsole. Referring to the Ultra Boost 4.0 which also has Continental rubber outsole, we think that the abrasive resistance should be good and enough for daily wearing and jogging.
Overall, Ultra Boost 19 has great improvement comparing with previous 4 generations. The design of appearance is more modern. And it has great improvement on the performance. Although it increase 20% of the Boost, the insole is high, but it’s still stable. The intensive Primeknit 360 knit makes the shoe like a sock. It can cover the foot very well. I’m surprised at the heelpiece. It’s stable and also fit well with the foot. The arch support of Ultra Boost 19 is also not bad. And it has great anti-torsion performance. It should be an outstanding running shoes without doubt.
