Product Details
Fit
Last: 103 mm – A wide last designed for out-of-the-box all-day comfort, especially for those with wider feet.
C.A.S. Shell – The C.A.S. shell has an anatomical shape that matches the foot shape. This allows for a better out-of-the-box fit. Dimples on the shell reduce surface tension and facilitate the thermo customization process, making it easier for a bootfitter to modify the shell to fit your foot.
C.A.S. Tongue – The C.A.S. Tongue can be thermoformed in a few minutes to perfectly match the shape of your shin.
Flex
Flex: 120 – A stiff flex for expert or heavier skiers who require quick rebound and ski response.
Liner
Performance C.A.S. Liner – C.A.S. liners are anatomically shaped for optimal comfort and great heel hold. The dual density micro-cell material is durable, easy to customize, and has a low pack-out rate maintaining a great fit over a longer period of time. For unmatched personal customization the C.A.S. liner can be thermo-molded, punched, and ground.
Celliant® Insulation – Celliant 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 performance, thermal regulation and faster recovery.
Shell Materials & Design
