Technology
1. 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.
Shell Features
- Anatomic and precise shape
- Easier and faster thermo-forming
- Easy customization
2. 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.
Liner Features
- Anatomic and precise shape
- Dual density pre-shaped thermoformed microcell material
- Great out-of-the box fit
- Enhanced sensitivity
3. T-Drive : Drive Precision. The T-Drive dynamic carbon connector creates a longer lever arm compared to traditional ski boots. This allows:
Features
- Quicker edge to edge transitions.
- Increased lateral power and stability.
- Edge drive precision.
Performance Efficiency : The T-Drive Technology creates a stronger and more effective connection between the cuff and the shell, that supports the boot flex and avoids plastic deformation. This means reduced energy dissipation and a more efficient power transmission.
Enhanced Comfort : Comfort comes from many places in the new Mach1 MV. The T-Drive technology provides a progressive flex regardless of temperatures, keeping the shape unchanged and a more consistent fit. The T-Drive support also allows the use of softer plastics, without compromising performances but making the boots easier to get on and off.
Ability Level : Expert
Skiers that have moved beyond the basics and feel more comfortable on the slopes making strong parallel turns with solid edge control. These skiers are exploring more of the mountain and ski the majority of the runs at most resorts, but still improving their skills to take on the hardest runs with confidence. The majority of intermediate skiers can adjust and manage their speed while adjusting to a variety of terrain and snow conditions.
Very experienced skiers that can easily tackle all types of terrain. Event at high speed, these skiers are balanced, controlled and confident. They ski efficiently with strong technique not matter what turn shape or at any speed. Expert skiers enjoy the challenge of variable conditions and terrain — from groomers to deep snow and tight trees to wide open faces - while adjusting quickly to unexpected obstacles along the way.
Flex
Given the needs and level of every skiers, we project models with different flex, thanks to the combination of different plastics.
- HARD (flex man 140-120) : for expert and more robust skiers
Width
The width of foot's sole changes from person to person, that's why our ski boots have different volumes to meet the needs of every skier.
- HV (high – 103mm) : for skiers with a wide foot's sole or for those who prefer a comfortable fit
