Tecnica Mach1 HV Dark Avio 275 Alpine Ski Boots

High performance ski boot designed for skiers with high-volume feet. The 103 mm last. The boot feels surprisingly comfortable out-of-the-box, thanks to the anatomically shaped liner and shell. You can add personal customization with Tecnica’s C.A.S. system to solve any additional fit problems. Advanced skiers will appreciate the Asymmetrical Power Transmission shell, which efficiently transfers all of your energy directly into the turn. 

C.A.S. shell

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 shape better and longer.

Shell features

• Anatomic and precise shape
• Easier and faster thermo-forming
• Easy customization

Shell customization

• PUNCHING (INCREASE VOLUME)

Polyether material can be heated and punched in problem fit areas.

• GRINDING (INCREASE VOLUME)

The shell can be ground in problem fit areas.

Asymmetric Power Transmission

The revolutionary asymmetrical concept is based on a different thickness of the shell and liner structures. The inside of the shell is slightly thicker and stiffer and the outside of the shell is thinner and more flexible.

Benefits:

• Increased lateral power transmission
• Increased edge grip
• Increased sensitivity
• Faster and more controlled edge to edge transition
• Anti-scratch finishing for higher durability

Quick Instep

Utilizes softer plastic over the instep area that allows the shell to open easier as you are entering or exiting the boot.
