The Rush Pro 4.0 for clay improves movement dynamics on the court thanks to a number of innovations in the midsole and outsole. The 4D Support Chassis 2.0 is an evolution of the Rush Pro 3.5 chassis construction, dividing the chassis into two parts to fulfil a dual purpose: one part passes under the foot for better support and forward propulsion, the other part passes laterally for greater stability and control. In the forefoot area of the midsole, Energy Cell features a lightweight EVA foam that optimizes the transfer of body weight at impact, enabling more explosive propulsion. The result is a shoe that takes the popular Rush Pro range to a whole new level in terms of design and performance.
