The COURT FF 3 tennis shoe is made to be like how Novak Djokovic plays tennis. These shoes are made to help you swing the tennis racquet harder and get ready for the next shot faster. Novak does a special move called a zero-step shot. That means he starts swinging his racquet as soon as he lands after a jump. The shoe makes landing stable and puts less stress on your body by making the bottom of the shoe touch the ground more. This way, you can use more power to hit the ball hard.
