The Wilson Rush Pro 4.0 boosts dynamic movement with 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 support and forward propulsion. In the forefoot, Energy Cell features a lightweight EVA foam that provides energy return for more explosiveness. Layer in a sleek silhouette, the result is a shoe that takes the popular Rush Pro franchise to all-new heights for design and performance.
