The CCM RibCor 68K Skates are constructed with a full-composite outer layer, which is lightweight, but also allows players to get the most power out of each stride. This composite outer layers goes hand in hand with the new FLEXFRAME Technology. This is the addition of flexion zones in the eyelet area, combined with strategic reinforcements in the rest of the core that offer a bio-mechanically correct stride. Additionally, the RibCor 68k Hockey Skates feature the 7mm felt tongue with lace-bite protection, offering increased comfort and protection. The RibCor 68K Hockey Skates also come equipped with CCM’s SpeedBlade 4.0 holder and stainless-steel blade, providing players with an increased attack angle allowing them to skate faster and turn sharper. If you are an elite-level player looking for a comfortable and high-quality pair of skates, look no further than the CCM RibCor 68k Senior Ice Hockey Skates!
