The Rush Pro 4.0 upgrades the dynamic court movement with innovation in the midsole and outsole. An evolution of the Rush Pro 3.5 chassis structure, the 4D Support Chassis 2.0 splits the chassis into 2 pieces for two purposes. One runs under your foot for added support and forward, and the other runs sideways, increasing stability and control. Energy Cell in the forefoot of the midsole features lightweight EVA foam designed to optimize weight transfer from impact and promote explosive propulsion. Layers in a sleek silhouette. The result is a shoe that takes the popular Rush Pro franchise to a whole new height in both design and performance.
