Lionel Messi and X Speedflow. They're all about fast thinking and faster feet. To mark Messi's return to adidas' speed franchise, these lightweight football boots take design cues from the F30s he wore in 2007, when he scored one of his greatest goals of all time. The raised forefoot, Carbitex carbon fibre insert, Agilitycage and adidas Primeknit collar will help you explode into action. Special packaging includes a booklet that looks back at that golden goal.
