The Rush Pro 4.0 Clash Edition upgrades dynamic court movement in a special design inspired by the Clash v2 tennis racket. An evolution of the Rush Pro 3.5 chassis construction, 4D Support Chassis 2.0 splits the chassis into two pieces for a dual purpose: one piece runs under the foot for enhanced support and forward propulsion, while the other runs laterally for additional stability and control. In the forefoot of the midsole, Energy Cell features a lightweight EVA foam designed to optimize the transfer of body weight through impact for more explosive propulsion. Layer in a sleek silhouette, and the result is a shoe that takes the popular Rush Pro franchise to all-new heights for both design and performance.
