The Alkali CA9 RPD Roller Hockey Skates are the flagship skates from Alkali Hockey.  Alkali took the boot of the 2011 CA9 and made some great upgrades by adding more foams and composite inserts in key areas. They also increased the size of the L pads in the ankle area helping eliminate heel lift.  The CA9 RPD rolls on the Alkali Magnesium frame and Labeda Addiction wheels with swiss bearings.  These paired together will give you great response with grip and breakaway speed.

The CA9 RPD has a super light but stiff quarter package made out of EPP foam and Surlyn.  This will provide great responsiveness and moldability.  Extra foams were placed in the eyelet areas for added strength .  Alkali also made the "L" bars or the ankle pads inside the boot bigger to increase ankle lock and eliminate heel lift.  3K carbon weave inserts were added to the back of the skate to provide reinforcement to the heel cup and make the tendon guard flex but keep its shape.

The CA9 RPD skate has an antibacterial microfiber liner.  This liner will help wick away moisture, keep you comfortable through your game and help fight odors and bacteria.  The tongue on the CA9 RPD has been upgraded as well.  It is a 3 piece black felt tongue with HD foams inserts to provide ultimate comfort and protection.  The tongue is also fully perforated to allow direct airflow to your feet helping them stay dry.

The Alkali Magnesium frames are attached to a full carbon fiber outsole.  These are going to keep this skate lightweight but also give you great responsiveness and maximum power transfer through every stride.  Labeda Addiction wheels with Swiss Elite 608 bearings will give you that breakaway speed but also maintain that control and grip.

Comments: Absolutely the best Inline Hockey skate I have ever had the pleasure to wear! I am a heavier skater and this super light, extremely stiff, perfect fitting skate is a welcome change to the usual inline. I have skated on the best skates out there and non compare to this boot! Components are top notch. The materials are second to none and the design is almost perfect. I recommend baking them twice. I baked them the first time, skated for about 8 hours and then baked them a second time and they are now perfect!
