The CCM RBZ 70 skate was created for the player that puts a high value on comfort and support, but still has a need for speed and wants to maximize explosiveness and reaction speed. It has a generous anatomical fit profile with a standard heel. Unlike the higher end RBZ skates, the RBZ 70 has a bit more of a traditional fit and follows the typical "1.5 sizes smaller than shoe size" rule of thumb. Skate fit, however, is ultimately a matter of personal preference. The outer shell of the RBZ 70 uses a sublimated tech mesh with a compound blend inner core. These two elements in conjunction with a relatively stiff inner layer, creates a sandwich-like construction that offers a good amount of lateral support. Heel lock is enhanced through the use of 6mm EVA foam, which is both comfortable and accommodating. The tongue is made of a combination of white felt with Added Lace Bite Protection. The RBZ 70 has a ventilated injected outsole which serves as the platform for mounting the SpeedBlade + 4.0 holder. This holder offers an additional 4.0mm height which provides a significantly deeper angle of attack for tighter turns, which will give you a competitive edge on races to the puck! SpeedRibs near the top of the holder help to increase torsional rigidity. The RBZ 70 senior model comes with the SpeedBlade Stainless Steel runner. Comfort, support and a holder designed to give you a competitive edge, the RBZ 70 skates from CCM are a great value. They also , happen to be among the lightest skates in their class. Worth considering, for sure.
