Continuing the evolution of our best-selling franchise, the Rush Pro 4.5 builds on the innovations of the 4. with new upgrades that improve breathability, support and abrasion resistance. The engineered mesh upper has a graduated pattern, with a larger hole mesh toward the front to promote airflow and a tighter mesh toward the heel for support. A larger, integrated medial mud guard provides all-around protection and support, while the enlarged rubber drag pad on the lateral side is extra thick to resist abrasion and anatomically shaped to follow the foot's profile. The Lightweight Energy Cell EVA foam under the forefoot provides cushioning on impact, then responds to help you spring back into position. Sleek, durable and providing multidirectional support, the Rush Pro puts your game on a great foundation, whatever the playing surface.
