The K2 Raider Inline Skates has all of the features needed to ensure a fun skating experience. The Traditional Lacing and the Stability Plus Cuff provide a secure fit with ample support, while the five-size adjustability allows the K2 Raider Skates to keep up with fast-growing kids. The vibration-absorbing composite F.B.I. Frame is interlocked with the base, keeping children more balanced by being lower to the ground.
