Hilbert's paradox of the Grand Hotel

The former Nike air cushion was formed in a resilient synthetic rubber layer which formed by pouring the air gas into a resilient synthetic rubber under a high pressure.

Air-Sole was a "mean" air cushion, which had a balanced performance in the cushioning ability, stability performance and reaction speed performance. And this technology is widely used in a variety of sports shoes even today.

Visible Air-Sole: This kind of air cushion was made the Air-Sole into a visible type, such as the heel portion of the AIR JORDAN 3 was used this visible Air-Sole. Being regarded as the transitional form between Air-Sole and Max Air, Visible 180 Air-Sole can perform a good damping force and a perfect visible impact.

The early Air Max was launched in the year of 1994, which appeared as the shape like the U-shaped, and changed into multi-sealed chamber Air Max and the trachea-shaped Tube Max Air. It possessed a multi-interval which was in multiple pressures, with a 5PSI pressure in the low pressure zone and 25PSI pressure in the high pressure zone.

Air Max cushioning ability was very strong, can provide appropriateness protection to your feet and your knees, but may cause the loss of machine power. Running shoes and basketball shoes were always adopted this kind of technology.
The only 4-8mm thickness air cushion-Zoom Air was an air cushion by using a three-dimensional fabric to keep its flat shape, and not it would turn to a ball shape, with the air pressure of 20PSI. The damping effect with an excellent sense of site sensitive rebound effect and excellent acceleration, Zoom Air was widely used in extensive outside basketball shoes (such as FLIGHT series, the AJ series), and speed of running shoes (such as Air zoom Miler).

Visible Zoom Air: The external visible Zoom Air was with greater capacity and better cushioning performance.
The Tuned Air: An integrated cushioning contained a hemisphere-shaped cushioning system to provide maximum force protection, stable and comfortable foot feeling, and its hemispheric body deformation can provide a changing air pressure. TN Air contained the PBAX thermoplastic material which can provide a fast reflection, rubbing, and lightweight, flexible and suitable feet feeling for the appropriate thickness characteristics, its hemispheric body pressure was 20PSI and the cushion pressure was 5PSI.

The total Air: This kind of air cushion can be regarded as nike running the larger version of Max Air palm, with 1.5cm extra length in the fore palm. Total Air Foamposite Max, namely "Steel", was the most typical example of Total Air Cushion.
SHOX: The special highly elastic foam materials (advanced PU materials) damping elastic column and double TPU trays jointed the Mid-sole mechanical damping technology. The SHOX may have different functions when applied in basketball shoes and the running shoes.� SHOX system can provide perfect damping performance, but people who are under the weight of 70kg can not have obvious feeling, and this system is widely used in all kinds of sports shoes

The simplified version of SHOX-the IMPAX changed the columnar bottom into a horizontal punch technology to perform an nike running excellent damping and stability performance
Nike developed IPS system which an provide relatively independent and organic complexes cylindrical shock absorber for the research and development of Air Jordan XX shoes, under the help of 20 pieces Phylon material with different density, thickness, size and location.
