The GEL-CHALLENGER® 13 tennis shoe from the NOVAK Pack is inspired by the idea of being there for one another and living uplifted. The shoe's supportive upper keeps your feet locked in on the shoe's platform. It creates a reinforced feel during volleys or when you're dropping back to track down deep lob shots. WINGWALL™ technology is placed in the sidewall to improve stability during side-to-side movements. This feature offers good support so that you can step into your shot and stroke the ball with more pace.
