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.
Celliant liner is powered by 13 thermoreactive minerals that convert body heat into infrared energy. Infrared penetrates deep into the tissue to increase circulation, oxygen and blood flow. This results in improved warmth, performance, thermal regulation and faster recovery. Lambswool offers additional insulation.
