Why don't domestic basketball shoes have air cushions?

The air cushion you mentioned should be the main technology of Nike, such as Air sole, Zoom air and Max air.

At present, Nike is the only company in the world with a patent on air cushion technology.

So other brands, such as Adidas, don't have this technology, but other brands also have their own technology. For example, the main technology of Adidas is a3 technology (the symbol is the cube of A).

Domestic basketball shoes can't develop air cushion technology such as NIKE ZOOM AIR for various reasons such as capital and technology.

If funds permit, I suggest you buy Nike shoes, which are of good quality, comfortable and cost-effective.
