Development:

Air Jordan 4 is inextricably linked with Air Flight89 launched in the same year. The same outsole and midsole design provides sufficient shock absorption and lateral support. Although it looks a little heavy now, compared with the air-cushion basketball shoes at that time, the midsole of this series is light enough.

The truly innovative design is the mesh material of Air Jordan4 upper. Before the appearance of Air Jordan 4, basketball shoes always appeared in front of people with a heavy image.

The mesh material that only appeared on running shoes before appeared on basketball shoes for the first time. This material not only greatly reduces the weight of shoes, but also liberates the feet of the wearer. The most important thing is that the permeability of basketball shoes has changed qualitatively.

Athletes no longer have to wear airtight "boots" to fight on the court. The elasticity of the mesh material greatly improves the ductility of AirJordan 4, and obviously improves the auxiliary function of athletes to change direction and start.

These are the great reforms of Air Jordan 4, or the reforms that Air Jordan 4 brought to the whole basketball world. A small idea has promoted the development of the whole basketball shoe product.
