The Alkali Revel 4 Skates usher in a new era of fit and performance for Alkali Hockey. The Revel 4 boasts the new IX construction process that gives this skate a high-performance, anatomical fit from heel to toe. They also used thicker foams throughout which also aid in fit but also significantly boost comfort too. Below the boot, Alkali debuts their new aluminum Rize chassis that elevates east-to-west agility without sacrificing top-end speed. With (2) larger wheels in the rear and (2) smaller wheels in the front, the Revel 4 puts players in the optimal, explosive skating posture. The forward lean of the boot and the toe spring also help out by gearing the skating stride specifically to roller hockey mechanics too.
