The Super Tacks AS1 Goal Skate is a one-piece boot and it's cut precisely for a goaltenders performance. Because it is made of a one-piece frame, it is stiffer in the lower portion and flexible upper half. This stiffness adds durability and performance. It also has and upgraded core that allows the boot to be molded to each players foot. The Super Tacks AS1 Goal Skates feature an anatomical fit that maximizes the contact with the players foot. CCM's TotalDri Pro liner helps wick moisture away from the skate the foot in order to keep the players feet dry, and this keeps the boot light. The AS1 also comes with a D30 footbed that increases comfort and performance.The holder on the AS1's helps give the goalie an advantageous attack angle for all pushes and recoveries. The runners are a high performance Prolite G Black blade. This oxide treatment gives the steel better edge retention as well as durability to wear and corrosion.
