TORUS tech is initiated as your feet and body enter a turn. As your weight shifts to the outer edges, TORUS bends and deflects with you to keep you up and skating at extremely sharp angles. You will not slip out. This is due to 1) the flexible side walls of the TORUS; and 2) the hollow design of the TORUs which allows for more room to flex.
The Integrated Structure Ring (ISR) built into the TORUS is a stiff and rigid support ring. As you are in your stride you are skating on what is called the "running surface" of the wheel. The ISR prevents the wheel from deflection, which creates structure and integrity within the wheel and allows for Speed.
