Designed for the leading motorsports crews, the FIA homologated Sparco MB Crew is equally at home in a co-driver's footwell. Two types of leather are used in its construction, one soft and one reinforced, for a comfortable and supple fit with excellent abrasion resistance. The high top boot features a padded ankle and tongue for support and comfort, with perforation strategically placed for maximum breathability. The fuel and oil resistant sole is designed for maximum traction for crew members and holds an ergonomic and shock absorbing insole.
