ASICS GEL-CHALLENGER 13 Asics GEL-CHALLENGER™ 13 Clay women's tennis shoes are the steady partner for any tennis player who wants to dominate. The upper is designed so that your foot locks into the shoe's platform for optimal stability. This creates a sense of empowerment when you are serving or back-pedalling, to run down deep lobs. WINGWALL™ technology on the sides improves stability during lateral movements. With this support, you don’t have to be afraid to give it your all, and hit the ball with all you have.
