The GEL-CHALLENGER® 14 tennis shoe creates the stability you need when you're covering the baseline, so you can keep your mind focused on controlling the point.​ 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.​ DYNAWING™ 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 outsole also features a separated heel construction to help you experience better stability during abrupt landings.
