The Supreme Ultrasonic is offered in our new Performance Fit System. It’s our ultimate performance skate for the elite player, designed to maximize power and control. A 3D Lasted Carbon Curv composite combined with a unibody sole stiffens the lower portion of the boot, allowing every push to build towards maximum energy transfer and faster straight line speed. Additionally, a power boot cut offers an increased wrap for optimal foot stability and support, creating a more powerful stride so that you can attack the puck better. It also features the Tuuk LS Pulse TI, our new ultimate performance steel. A titanium coating gives it better edge retention and grip, providing more consistency during use, while maintaining speed. This new blade is also equipped with Bauer's Power Profile*, which helps the player maintain speed and a more powerful stride. Finally, the Reflex Tendon Guard, Reflex PRO tongue, and Flex Facing all work together to improve range of motion, increasing every stride’s length and level of power. The Ultrasonic’s Flex Rating is 90; it’s our most supportive boot, which provides incredible stability for the elite skater.
