DESCRIPTION The GEL-CHALLENGER 13 paddle 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 support upper keeps your feet locked on the shoe platform. It creates a reinforced feeling during volleys or when backing up to look for deep shots. WINGWALL technology is placed on the sidewall to improve stability during side-to-side movements. This feature offers good support, so you can advance your shot and hit the ball with more pace.
