The boot is worn by the French superstar Kylian Mbappé. Mercurial Air Zoom brings a new kind of propulsion and speed to the wonderful world of football. For the first time in history, Nike has developed a 3/4-length Zoom Air unit placed in the sole, providing extremely efficient and responsive foot transition that sends you rocketing towards the goal. Premium upper made of a synthetic material combined with durable mesh that wraps around the foot for the best fit, as well as optimal ventilation and comfort. Internal speed cage made of a thin but strong material that holds the foot against the sole without adding extra weight, creating a secure lockdown. This is a shoe with a TF outsole, making it suitable for use on artificial surfaces such as synthetic and gravel fields.
