An ultra-lightweight boot which is 40% lighter than a standard race boot. The Sparco Superleggera RB-10.1 is mMade with a fire retardant fabric that can be personalised including the use of prints if required. The panels are made from the finest lightweight kangaroo skin which is much more wear resistant than normal hide. The ultra-light soles adapt perfectly to all types of heel. Integrated lateral reinforcement. The RB-10.1 race boots feature a stretch fabric tongue wraps around the foot like a second skin and prevents dust, dirt or other materials from entering the shoe. An elasticised panel at the rear just above the heel improves fit and allows the ankle to move freely when driving. The end result is an ultra-lightweight boot for racers which provides maximum driver sensitivity for a drive without compromises.
