The Sparco Formula RB-8 driving shoe features a next generation sole made in pure lightweight rubber which enhances the pedal feel and is also anti-static, fuel and oil resistant. The mid-boot design has a full ultra-soft calf skin leather upper with perforated vents. The upper has a Hook & Loop strap closure and Speed Laces for better support and adjustability (standard laces also included). Another unique feature of the Formula RB-8 driving shoe is the Achilles stretch panel for improved mobility and comfort.
