The Most Advanced Soccer Ball We’ve Ever Built. Period. Introducing the all-new FT553B. Completely reimagined from the ground up, with aerodynamically-designed convex material that results in a 47% improvement in softness and durability. A thicker, more flexible cover material and added sponged cushioning creates a lively feel and enables superior control. Also new is a hybrid blend of natural and synthetic rubber combined to improve air retention by 38%.
