Take control of the tennis court and pair the Rush Pro 4.0 Special Edition Shift Clay Tennis shoes with the Shift V1 performance tennis racket. The Rush Pro 4.0 Clay's two midsole and outsole advancements provide dynamic court movement. The Rush Pro 3.5 chassis architecture has evolved into the 4D Support Chassis 2.0, which divides the chassis into two sections for improved forward propulsion and support under the foot and extra stability and control on the side. Energy Cell has a lightweight EVA foam in the forefoot of the midsole that is optimized to transfer body weight during impact for more forceful propulsion.
