The Rush Pro 4.0 is the latest evolution of the Rush Pro franchise. The new bottom unit has been reinvented to bring more dynamic movement for the explosive attacking player that wants to control the game. The latest technology in the Rush Pro 4.0 is the Energy Cell technology. It’s a new foam developed with Salomon, Wilson's sister company. It is used in the midsole to give it more energy and power to the player. To enable them to move forward faster, with more explosivity. It’s a foam that’s unique. It’s resilient and a bit softer, so it’s very comfortable but has a lot of pop. Really that was our focus and goal: to give more energy to the Rush Pro 4.0.
