The C.A.S. Shell has an anatomical shape that matches the shape of the foot. This allows for a better out-of-the box initial fit. The dimples on the shell offer less surface tension and facilitate heating, making customizing the shell easier. The shell retains the new shape better and longer.
Innovative Lift Lock system holds the buckles up and out of the way so they don't catch while getting in or out of your boots.
Utilizes softer plastic over the instep area that allows the shell to open easier as you are entering or exiting the boot.
