The CX series models are designed for kids who want to work on their technique, yet need warm and comfortable boots that provide excellent performance. Putting them on and taking them off is really easy, and the fit and flexibility mean that you can concentrate completely on riding. The CX 4.0 features a four-buckle fastening system and stands out for its excellent power transmission, which will be a treat especially for ambitious kids with a competitive streak. As an option, GripWalk soles can be added at a later date, providing significantly improved comfort when walking.
