The Alkali RPD Max Roller Hockey Skates are the premier model in the RPD Skate Line. This RPD Max features the magnesium Labeda Movement chassis with premier Labeda Addiction (XXX Grip) Wheels for superior speed and grip. Alkali had the chassis specifically made for these boots to provide an aggressive turning radius with excellent power transfer through each stride.

When looking directly at the full carbon composite outsole, there is a low-profile cutout that allows the second wheel from the toe to recess into. This was a collaboration design between Alkali and Labeda to give the RPD Max a lower center of gravity, a tighter turning radius, a better overall balanced feel and a more efficient power transfer during the striding process. To provide the high class speed and grip that advanced players are looking for, the Labeda Addiction (XXX Grip) Wheels with Swiss Lite 608 Bearings were used.

The Hyper Light Quarter Package is made of a high quality EPP Foam that is very lightweight and has been widened in the forefoot by 2 mm. The Pro 9 mm White Felt Tongue is perforated for good airflow while the high-density lace bite guard protects the top of the foot. The liner is a soft hydrophobic material with anti-slip properties so that a player’s foot stays dry and does not slide internally.
