The carbon shell is very light due to its new production, but it has no effect on the overall strength. Thanks to My Fit technology, the inside of the shoe can be warmed up and adjusted to fit your foot. The Trinity mounting system is a new gripping system that allows the wheels to be as close to the shoe as possible, reducing the center of gravity, increasing stability, more damping the vibration induced by the ride, better transmitting force to rebound and providing more control during skating.
