The GEL-RESOLUTION™ 9 CLAY tennis shoe creates advanced stability and cushioning for players who like to control the game from the baseline. DYNAWALL™ technology in the midsole now extends into the heel for added stability during lateral movements. It's a functional feature that's effective when you're running covering both sides of the baseline.
