Cristiano Ronaldo would not be the competitor he is, without setbacks. This version of Vapor Academy 15 is designed to take your game to the next level, and has haunting ripples representing the sagas we endure, while energetic greens represent the breakthrough that arises when we overcome obstacles. You also get an Air Zoom unit so you can speed up properly again in the last minutes of a game, when it's most important. The Air Zoom unit in the heel area is located on the outsole and provides an additional, stretchy underfoot feel that helps you move quickly across the field. She creates distance when it matters - no matter if you shoot goals, you're the first to reach the ball or pass through the defenders. Unique traction pattern provides super strong traction with quick release to create a separation. A revised design improves the fit to better simulate the foot. To do this, we have conducted several usage tests with hundreds of athletes. The result is a better contoured toe and a better fit in the heel area. The upper is made of NikeSkin, a soft and flexible mesh material bonded together by a thin layer. Supports ball control and provides a true barefoot feel. The speed cage inside the structure is made of a thin but strong material that secures the foot to the sole without extra weight.
