The top-of-the-range Sparco PRIME EXTREME driver shoe , developed in close collaboration with the RED BULL F1 team, impresses with its upper made of ultra-light and supple fabric. The extremely light laces, the breathable inner lining, as well as the ultra-thin F1 sole reinforced with carbon fiber for an outstanding pedal feel and the transparent silicone reinforcements make this shoe a first-class choice.
