The S-TR1 Air is the new sporty boot that combines high TCX quality standards with maximum protection. It has been designed to protect the foot, ankle, and shin, offering a perfect balance of safety and comfort. Ventilation is optimized through the perforated shaft and the front joint made of breathable mesh with integrated hotmelt bands, providing ideal comfort even in high temperatures. The front protection is ensured by the upper rigid TPU structure and the soft lower padding: the synergy of the innovative and functional design of the shin guard with the padding guarantees excellent flexibility of the boot. The movement of the joint is controlled by the TCS (Torsion Control System), which has been specifically developed to accompany the ankle in its optimal range of motion, thus preventing unwanted twisting, hyperextension, and hyperflexion. The Groundtrax® sole with a specially designed profile ensures perfect grip on the motorcycle pedals and on asphalt, in all weather conditions.
