CAS Liner - CAS has revolutionized ski boots in terms of fit. The insoles are anatomically shaped for optimal comfort and offer great heel support. The inner part of the insole is shaped to conform to the foot, while the outer part tunes and adapts to the shape of the skeleton. Dual-density micro-cellular material is durable and easy to adjust. CAS linings retain their shape for a longer period of time.

Features:

Celliant Technology - The Celliant insert is powered by 13 thermoreactive minerals that convert body heat into infrared energy. Infrared radiation penetrates deep into tissue to increase circulation, oxygen and blood flow. The result is better warmth, performance, thermal regulation and faster regeneration.

CAS Shell - The CAS shell has an anatomical shape that corresponds to the shape of the foot. This enables a better adaptation of the ski boots to your feet. Dimples on the skeleton reduce surface tension. The skeleton materials allow better and longer preservation of the adapted shape.

Features of CAS Shell:

• Anatomical and precise shape
• Easier and faster hot forming
• Easy customization

T - drive - The dynamic T-Drive carbon connector creates a longer lever arm compared to traditional ski boots. This allows:

• Faster transitions
• Increased lateral strength and stability

Performance efficiency
The T-Drive technology creates a stronger and more efficient connection between the cuff and the shell, which supports the flex of the shoe and prevents deformation. This means reduced energy dissipation and more efficient power transfer.

Increased comfort
T-Drive technology provides a progressive bend regardless of temperatures, keeping the shape unchanged and more consistent. The T-Drive support also allows the use of softer plastics without compromising performance, but makes it easier to put on and take off.

Lift Lock System - The innovative Lift Lock system holds the buckles up so they don't get caught when you put on or take off the ski boots.

Quick Instep - Uses softer plastic in the instep area, which allows for easier opening of the skeleton when putting on and taking off ski boots.

Volume Concept - the anatomical shape of the lining and skeleton of the ski boot are the key to perfect fit and comfort.
The more the lining and skeleton match the natural shape of the foot, the better they fit the foot and enable you to perform better.

It is ideal if the ski boots fit on your feet immediately after unpacking from the box. In order for you to make the right decision before buying and to guarantee a perfect fit for every foot shape, Tecnica Mach models offer a choice of three skeleton width options, which are already mentioned in the model name:

• LV - Low Volume: 98mm
• MV - Mid Volume: 100mm
• HV - High Volume: 103mm
