The Rush Pro Tour personifies power, stability and dynamic court movement thanks to two innovations in the midsole and outsole. Energy Cell comprises a lightweight EVA foam in the forefoot of the midsole for a softer feel and quicker transfer of body weight through impact, creating more powerful acceleration. 4D Support Chassis 2.0 splits the chassis into two pieces for a supreme combination of lateral stability and forward propulsion. The additional support around the ankle makes this a can't miss shoe for tennis players with a history of ankle injuries. Slick design, dynamic performance and remarkable stability combine to serve up a formidable, game-changing shoe for aggressive tennis players.
