Air
Nike Air units work by trapping air molecules inside a durable urethane shell. With each footstrike, the air unit compresses to reduce the force of impact, then immediately recovers its shape to be ready for the next landing. Nike Air units are built to last, so the cushioning properties hold steady for the life of the shoe.

Flyknit
It uses a knitted upper construction process that increases support for a comfortable, custom fit. Seams, weight and friction areas are all reduced. Polyester yarn is more open in areas that need more flexibility and tighter in areas that require more support. Nike Flyknit also eliminates the need for multiple materials used to make traditional shoe uppers, significantly reducing pollution.

ZoomX
ZoomX foam guarantees the highest level reactive energy return among the actual Nike shoes in production today. The weight of ZoomX is lower than 1/3 with respect to the Cushlon foam in essence it has all the advantages in terms of maximum cushioning at a reduced weight.

A mix very similiar to the ZoomX was used predominantly in the aerospace industry, but for some time has this innovative technology has been found in high performance shoes.

The ZoomX foam sheets are made with autoclaves in extreme heat and pressure conditions: to obtain the final component of the midsole, the product is cut into predefined shapes and then inserted into compression molds.
