Dominate the court and match the Shift V1 performance tennis racket with the Special Edition Rush Pro 4.0 Shift Tennis shoes. The Rush Pro 4.0 upgrades dynamic court movement thanks to a pair of innovations in the midsole and outsole. 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 a design inspired by the latest Shift collection, and the result is a shoe that takes the popular Rush Pro franchise to all-new heights for both design and performance.
