The Torsion Control System®has undergone modifications and been perfected, increasing its functionality and safety performance of the TCX Competizione S. The system has been noticeably updated and is now made up of 4 combined elements. The main structure has a double heel and a frame that allow lateral and longitudinal movement of the ankle, preventing torsion beyond natural limits and therefore protecting the joints from possible injuries. This main structure is connected to an X-shaped central body sewn to the upper, that connects the upper part to the lower part of the boot and guarantees excellent hold for the leg. The steel slider has been designed to protect the heel and favor the natural sliding motion in the case of a fall.
