C.A.S. Shell 
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.

+ Anatomic and precise shape
+ Easier and faster thermo-forming
+ Easy customization

C.A.S. Liner
C.A.S. has revolutionized ski boots with regards to fit and personalization. The liners are anatomically shaped for optimal comfort and offer great heel hold. The internal part of the liner is shaped to match the foot while the exterior matches and conforms to the shape of the shell. The dual density micro-cell material is durable and easy to customize. The C.A.S. liners are less prone to pack-out maintaining the fit over a longer period of time.

+ Anatomic and precise shape
+ Dual density pre-shaped thermoformed microcell material
+ Great out-of-the-box fit
+ Enhanced sensitivity
