RBZ skates from CCM are built to be Freakishly Fast. The brand new Speedblade + 4.0 holder gives you extra height off the ice for a deep and aggressive angle of attack. The Speed ribs give additional strength and stability to the skater. This combination provides exceptional turning in tight corners. In addition, the SB Hyperglide runner brings less friction and more glide, so get ready to strap a rocket to your feet with the RBZ skates. The RBZ 90 is constructed using new Action Form composite quarters for a reinforced outer shell that is fully heat moldable for a custom fit. The skates liner features Duratex which provides a good balance between durability and moisture wicking for long term comfort. With the speed generated from the holders and steel, the skate needs a stiff outsole too keep you balanced, and the Fiberglass Composite exhaust outsole ensures maximum energy transfer and a reactive feel to keep you balanced and moving.
