Does Yushuai 13 have water pump technology?

There is no such thing.

Li Ning successfully polymerized four kinds of polymer materials with different physical properties, such as EVA and rubber, by chemical means, forming the basic framework of the midsole.

At the same time, the gas generated by the foaming agent added in the formula can fill the whole frame structure and form countless micro "airbags".

When the midsole material of "Li Ningyun" hits the ground, the "airbag" will deform under pressure, quickly absorb the impact force and reduce the damage to human feet. This is a process of absorbing energy and also a process of buffering.
