The GEL-CHALLENGER 15 tennis court shoe is ideally suited for the beginner to mid-level tennis athlete who controls the game from the baseline. It offers high durability and good stability for multi-directional movements. The shoe's soft, yet supportive upper is also met with a thicker collar to help create a more comfortable wrap around your foot. WINGWALL technology is placed in the sidewall to improve stability during side-to-side movements. This feature offers good support, so you can step into your shot and stroke the ball with more pace.​ The full-length outsole and separated groove design helps create a larger contact area. This helps create softer landings for better overall comfort.
