The Sparco Prime EVO race shoe was designed for Formula one use and is currently being used by Formula One drivers. Formula One teams are always pushing for weight reductions and Sparco created some innovative solutions. The Prime EVO is one of the lightest race shoes available. It features a full Velcro closure system which gives a very secure and comfortable fit. The lightweight perforated Velcro closure covers a breathable stretch panel tongue which is extremely comfortable. The Prime EVO features a Carbon Fiber sole. The special Carbon Fiber was developed by Sparco Engineers in the Sparco OEM Division. This carbon fiber is unique because it has been developed to be flexible, it is inlayed into the sole and runs from the toe box to the heel. Carbon Fiber is visible through the window of the ultra-thin oil-resistant and anti-static sole which offers greater pedal sensitivity. The cushioned inner sole has another unique feature, it has a printed silicon pattern which gives added traction and pedal feel. The PRIME EVO is FIA 8856-2018 Approved.
