The True Shift Max Stainless Steel Runners are the standard replacement runners for the True Shift Max Holder and are featured on the True Catalyst 9 Skate. They are built with a height of 18mm which provides players with sharp turns and extended sharpening life. In addition, they are made of high-grade steel to offer excellent durability. True also designed the Shift Max Stainless Steel Runner with a dual profile, meaning they have a 9' radius on the front and a 10' radius on the back. This radius combination helps to maximize blade contact with the ice in different skating situations, thus improving acceleration, stride power, balance in the corners, and overall maneuverability.
