Sparco's Prime-R racing shoe takes the highly breathable approach that brought the Prime-T, but in a more traditional design. Flat laces are added to the ultra-lightweight shoe, with a single thin velcro strap that not only provides additional ankle support, but acts as a lace-keeper. The preforated leather upper maximizes breathability, and compliments the highly breathable inner fabric. The heel is designed to dampen vibrations, an excellent feature for today's most powerful race cars, while the thin rubber sole features a contrasting grip texture to maximize pedal control. Abrasion resistant leather inserts are strategically placed on the outside of the shoe to increase durability and scuff resistance.
