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:

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

Asymmetric Power Transmission - The revolutionary asymmetric concept is based on the different thickness of the skeleton structures on the outside and inside. The inner side of the skeleton is slightly thicker and stiffer, and the outer side of the skeleton is thinner and more flexible.

Advantages:

• increased lateral power transmission
• increased edge adhesion
• increased sensitivity
• faster and more controlled transition from edge to edge
• anti-scratch surface treatment for higher resistance

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
