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

Therm-ic Heat Control - technology enabling thermal heating of ski boots by connecting ski boots via Bluetooth to your smartphone. Download the Therm-ic Heat Control app for free and heat your ski boots to the temperature you want. The batteries with charging cable and the heating parts are integrated directly in the ski boot and the power supply is simple with a USB cable.

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
