Certified sports motorcycle boots designed to combine maximum safety with optimal comfort, even in the hottest climates. A combination of TCX's high quality standards and maximum protection, the S-TR1 Air is the new sporty men's motorbike boot designed to protect the foot, joint and shin, a perfect blend of safety and comfort. Front protection is provided by the upper rigid TPU structure and the lower soft padding.

Ventilation is optimised by the perforated upper and the breathable mesh fabric front with incorporated hot melt bands for ideal comfort even at high temperatures. The Groundtrax sole guarantees perfect grip on the bike's pedals and asphalt, in all weather conditions. CHARACTERISTICS: Ortholite footbed with hard-wearing padding and high breathability.
