The Formula RB-8 was developed using feedback from Sparco’s professional drivers. This development program created some unique features for the new shoe. The Formula RB-8 has the 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 features a full ultra-soft calf skin leather upper with perforated vents. The upper has a Velcro strap closure and Speed Laces for better support and adjustability (standard laces also included). Another unique feature of the Formula RB-8 is the Achilles stretch panel for improved mobility and comfort. The Formula RB-8 has a pre-formed anatomic insole.
Driving and racing shoes are usually slightly narrower than athletic shoes. Most drivers like their shoes to fit as snugly as possible to increase pedal feel. If you are between sizes and like your shoes to fit snugly, choose the smaller size. If you are between sizes and have a wide foot or do not like your shoes to fit tight, opt for the larger size.
