For those of you that aren't familiar with that technology, the Advanced Pump® allows you to control the amount of air that you circulate into the air bladders around the ankles, thus enhancing heel lock by eliminating negative space and giving you the option to adjust for fit in a matter of seconds between shifts. It is more efficient than its predecessor as it fills quicker and holds more air. The RIBCOR 48K has a tapered fit in the ankle and is slightly narrower in the heel and the forefoot in comparison to the Tacks and RBZ lines from CCM. You'll also find the Skate Lock feature on this skate, which allows for variability within two separate lacing zones - lower and upper.
CCM uses its RIBCOR Flex + Durafilm construction in the quarter. This nylon reinforced EPP foam core reacts very well to heat molding, and will help reduce break in time. The two elements of the agility profile that contribute to forward and backward flexibility are the boot cut and the 13° forward lean (RBZ is 10°, while Tacks are 16°). Heel lock is achieved from a combination of a tapered fit in the ankle, the use of internal ankle foams, the Skate Lock feature and the Advanced Pump®.
