The Sparco Superleggera RB-10.1 is the ultimate ultra-lightweight driving shoe. It was specifically designed for top-level professional drivers who are looking to save weight every way possible.  The Superleggera RB-10.1 is 50% lighter than a standard racing shoe by using a combination of kangaroo leather and light weight fabric. The Kangaroo leather is more durable than standard leather but equally soft. Along with the Kangaroo leather the main panels are made from soft, fire resistant fabric. The stretch fabric tongue wraps around the foot like a second skin and prevents dust, soil or other materials from entering the shoe. The Sparco Superleggera RB-10.1 also has a reinforced stretch panel above the heel to improve movement when in the driving position. This combination provides an extremely comfortable fit, highly breathable and offers a high level of protection. The ultra-thin oil-resistant and anti-static sole offers comfort and greater pedal sensitivity. Available in black in sizes from 38 to 48.
