1. Most domestic sports shoes follow international brands and imitate international brands, and their scientific and technological innovation ability is seriously insufficient.
2. The existing sneaker technology can support the sports needs of domestic non-professional athletes, while professional athletes choose more advanced and stable international sports brands.
3. Each sports brand has its own core technology, which belongs to patents (such as ZOOM, sole, fit of NK, cool of Adi, Honeycomb and Airbag of Reebok, etc.). Even if domestic sports shoes want to join these new technologies, they have to pay high patent fees to these brands, which greatly reduces profits.
