Only Nike has air cushion technology?

Nike was the first company to use air cushion. Needless to say, that's because they are close to NASA, and the technology developed by NASA can go to the moon first (of course, it is also said that NASA engineers who invented air found Adidas first, but Adi ignored them, and Adi was much better than Nike in the 1980 s).

Adi has also introduced air cushion shoes, which will be earlier than other brands, and should be more than 90 years old.

Then, I don't remember the left and right starting points and the middle concave technology of air cushion shoes by and 1.

Li Ning has also introduced airbags, but there are not many styles.

Some skateboarding shoes in the United States, such as DG, have also introduced skateboarding shoes with a starting point.

There are too many small brands in China, so I won't talk about it.

Air's patent expired in 2002 (it seems to be in 2003 or 200), so Nike introduced airmax 360 to commemorate this cross-century technology. With the expiration of the patent, many brands can use this patented technology (at least in the United States).

But unfortunately, due to the demand of brand differentiation, other brands did not regard air cushion as the mainstream technology.

Analog devices is usually the first company to introduce a new generation of technology. The technology of Tianzu in the 1990s, the electronic technology of 1 shoes in the new century, and the ground control formotion later were all ahead of the current technology, but unfortunately, Europeans care about technology and are much worse than Americans in marketing.
