The CCM 2.0 12J ice skates are junior ice hockey skates from the brand CCM. "2.0" likely refers to the model name (or an updated version of a previous model), and "12J" indicates a junior size 12, which corresponds to approximately 21cm (actual size). These skates are designed for beginners to intermediate players and feature blades with a curved profile for easy turning and quick changes of direction. Thank you for viewing.
