The RT-Race Pro Air motorcycle boot is the top-of-the line Racing model, resulting from collaboration between the TCX R&D Department and professional MotoGP riders. RT-Race Pro Air incorporates Fasten Fit Control, an internal lacing system connected to the boot lining through a quick-slide lace, so that the upper can wrap round the foot as much as possible and the fit can be personalized right down to the millimeter. The boot fastening system features an aluminum lever with micrometric adjustment and quick release, designed so that the shaft can adapt perfectly to various calf shapes, and a side zipper with stretch panel. TCX RT-Race Pro Air motorcycle boots are equipped with the anti-twist Double Flex Control system, a polyurethane joint in the ankle area able to control movement down to the millimeter, offering ideal joint support and flexibility, to prevent dangerous twisting and the risk of injury. The upper is made of highly wear-resistant microfiber and perforated, to ensure optimal ventilation for the foot and maintain perfect comfort even at high temperatures.The inner lining is made of breathable AIR TECH mesh fabric and has a padding with different thicknesses in the ankle area to offer maximum comfort. The “Burnout” sole created by TCX in collaboration with the Michelin research center is inspired by the Michelin “Power Supersport Evo” tire. It features a bi-compound tread with differentiated grip areas, designed to ensure superior grip on foot pegs and controls and greater resistance to wear and abrasion from asphalt. The profile is fully integrated with the upper and the heel angle ensures optimal position on the foot pegs. There are interchangeable magnesium sliders on the toe and heel to aid sliding when in contact with the asphalt. There are more polyurethane reinforcements in the most exposed areas, such as the shin, ankle, toe and heel.
