The one-piece construction and strength of U Foam allows the skate to form to the ankle without any limitations. Unlike the competition, there are no additional ankle counters or existing shapes. The end result is an ankle shape determined by the player's unique ankle positioning and shape. Added soft foams improve step-in comfort. U Foam coupled with a new heel pocket construction, allow the heel to lock into place. When heated this construction allows the player to create their own heel pocket to lock the heel into place. This differs from the competition, since they force every heel into one preset shape. When heated, the U Foam gets very soft and fuses to the player's unique foot. By fitting so close to the foot, the result is instant reaction leading to better agility and a more powerful push off. U Foam makes up for any abnormalities versus the perfect foot and cools down in the shape of the unique foot. Stronger than any core construction CCM has ever used for maximum energy transfer and push off Extremely reactive when heat molded, it molds to your foot as one piece for a truly customized fit. The end result is direct response and agility. Lightweight for greatly increased foot speed and acceleration.
