The Nike Zoom Vapor 12 is one of the best lightweight tennis shoes on the market. This makes a return to form for Nike's best-selling model with improved durability and support. The Vapor 12 fits very similarly to the Vapor X in that they run a little on the small side. For the best experience, consider ordering a half size larger than normal.
Adaptive Fit System
While the adaptive fit system has been present in the Vapor franchise for generations, the application on the Vapor 12 draws a striking resemblance to the famous Vapor 9.5.

The adaptive fit system allows the upper and tongue to wrap the foot for comfort and support. It also allows different foot shapes to remain comfortable during long hours on the court. The application of the system on the Vapor 12 puts the player in charge of customizing the fit to their needs.
Upper Redesign
As the name "Vapor" suggests, Nike removes as much excess weight as possible to promote a faster ride. The engineered mesh is lighter in the Vapor 12, and it maintains durability in the high-wear medial-toe section. The medial side offers more abrasion protection than any previous Vapor model, and it has a similar look the the more durable Vapor Cage Rafa.

Full-Length Foot Frame
The firm foot frame wraps around a supportive midfoot plate and spans heel to toe, providing a secure fit. It provides the needed stability to transfer power during dynamic court movements. A midfoot fit band allows cinching the laces tighter to enhance the fit and enable faster cuts.

The Shank is Back
The supportive plastic piece allowed Nike engineers to remove the rubber in the midfoot, which further reduced the weight. The split-sole design and plastic plate delivers optimal stability and transitions when cutting from side to side.

Zoom Air is Back
A heel Air Zoom unit helps keep you supported and springy throughout your match. In addition, a midsole foam was added between the plastic and rubber to help keep you light on your feet.
Outsole
The herringbone traction pattern is made of a new rubber compound, which is lighter than the previous Vapors. It allows a direct cut, plant, and move back into position without feeling a loss in speed or stability
Wrap Up
As you can see, the Nike Vapor 12 is influenced by some of the most popular features of the previous models, but it also delivers a striking new silhouette which is sure to be the standard in speed for years to come. The Zoom Vapor 12 is available in men's and women's sizes, and Nike will release PRM versions to coincide with the biggest tournaments in the world.
