The Superleggera RB-10.1 racing boots have FIA 8856-2000 type approval. They combine fire retardant fabric, which can be personalised with prints, with soft and lightweight panels in kangaroo leather, which is far more resistant than normal leather. The unique, ultra-light soles adapt perfectly to all foot sizes, while a stretch fabric tongue wraps around the foot like a second skin and prevents dust, soil or other materials from entering the shoe. The Superleggera RB-10.1 racing boots have an elasticised panel at the rear just above the heel to improve fit and comfort, and allow the ankle to move freely when driving. The Superleggera RS 10.1 boots are available in black (customizable, upon request, in line with the Sparco guidelines) and in sizes 36 to 48.
