The Juniors` Vapor Pro Tennis Shoe is an update to one of the most popular shoes on the pro tour. Nike designed the Vapor Pro to be lighter and more stable than the shoe's predecessor, the Vapor X. The innovative three layer design places breathability, stability, and durability features where they are needed most, but without adding excess weight. The Juniors' Vapor Pro looks to continue the high performance tradition we have come to expect from the Nike "Vapor" name.
