Reebok's 11K Pump Inline Skate is faster and more powerful than any Reebok inline skate to date. Partnering with Labeda to offer unparalleled speed and control, the 11K skate is on the cutting-edge of technology. Connecting player to rink are revolutionary Labeda Addiction wheels, with a first of their kind makeup of outdoor wheel hardness with an indoor wheel grip. This gives you quicker speed, amazing wear, and grip all day long. ABEC 9 bearings provide speed while a more rigid Labeda chassis holds all 4 80mm wheels in place. This combination of grip, durability, and speed form one of the best combinations available. Providing support for all this grip is Reebok's super-lightweight Pro Armour IV boot. Comprised of a lightweight core and durable outer shell, the Pro Armour IV boot is embedded with composite materials that not only reduce weight, they also serve as structural supports, giving the boot a truly solid feel that is ideal for high agility situations. A full composite outsolde minimizes mass and maximizes energy transfer for a highly reactive and resposive feel. Rounding out the boot, and unique to Reebok are are an improved Pump and Lace Lock. The Pump, with a more targeted internal air chamber better eliminates natural gaps around the ankle and gives you a more comfortable fit while preventing heel lift. The Lace Lock allows you to tighten your laces just right and lock them in place for the entire game.
