Blending TCX's high-quality standards and maximum protection, S-TR1 Air are the new sports boots designed to protect foot, joint and shin – the perfect balance between safety and comfort. Ventilation is optimized by the perforated upper and the front joint in breathable mesh fabric with integrated hot-melt bands – for optimal comfort even at high temperatures. Front protection is guaranteed by the upper construction in rigid TPU structure and lower soft padding – an innovative and functional design for padded shin protection resulting in boots boasting excellent flexibility. The TCS® (Torsion Control System) – specially designed to accompany the ankle as it moves through its optimal range of action – guides the movement of the foot joint, thus avoiding the risk of unwelcome twisting, hyper-extension and hyperflexion. The Groundtrax® sole boasts a specially designed tread that ensures perfect grip on the motorcycle’s controls as well as on asphalt, in all weather conditions.
