The F50 boot incorporats what Adidas calls Fusion Frame System technology. Adidas claims this lets players vary the feel and performance of their shoes according to playing style and conditions during a game. The concept of the shoe provided a boot and three different chassis. Each chassis consists of a special mixture of polymer intended to adapt in performance and character to the player.
The upper of the F50 is made of comfortable leather and Engineered Mesh, which Adidas says adds stability with little weight. A covered quick lacing and “single pull system” fits the footwear around the foot.
