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.

Our Zero G Tour Pro liners are anatomically pre-shaped to deliver the best fit out of the box. The dual-density, C.A.S. microcellular material around the heel area is positioned to deliver great heel retention. If required, C.A.S. material can be grinded and thermo-molded for further personalization. The new flex structure on the back of the liner guarantees even easier hiking. In addition, it features Recco reflector technology for additional safety. Finally, the waterproof, breathable membrane keeps feet warm and dry all day long.
