Tecnica Mach HV BOA 100 Men’s Ski Boot

Tecnica Mach HV BOA 100 Men’s Ski Boot combines a high-volume anatomical fit with Tecnica’s BOA® Fit System to deliver a comfortable, precise and highly adjustable ski boot for all-day resort skiing. With a 103 mm last, 100 flex rating and GripWalk® soles, it is designed for skiers who want dependable performance without sacrificing comfort.

Key Features

• BOA® Fit System – Provides precise micro-adjustment and a more uniform wrap around the foot for improved heel hold and edge-to-edge control.
• 103 mm HV last – High-volume fit designed for wider feet or skiers who prefer a more comfortable, less restrictive fit.
• 100 flex – Medium flex suitable for intermediate to advanced skiers seeking a balance of control and comfort.
• C.A.S. Shell – Anatomically shaped shell improves the out-of-the-box fit and can be customised through thermoforming and punching.
• N.F.S. Adaptive liner – Anatomically pre-shaped with soft, supportive padding for warmth and comfort.
• GripWalk® soles – Improve walking comfort and traction while maintaining compatibility with GripWalk bindings.
• Double Quick Instep – Softer plastic around the instep makes the boot easier to put on and remove.
• Lift Lock buckles – Keep buckles raised and out of the way when entering or exiting the boot.
• 45 mm Velcro power strap – Provides additional support around the upper cuff.
• 12° forward lean – Provides a balanced stance suited to all-mountain resort skiing.

BOA® Fit System

The Mach BOA HV 100 uses the BOA® Fit System to replace the traditional lower-shell buckle with a dial-operated closure. Micro-adjustments allow the fit to be fine-tuned while skiing, helping distribute pressure more evenly across the foot and improving heel retention and responsiveness.

The system is specifically integrated into the boot’s anatomical high-volume shell rather than simply added as an alternative closure, creating a more consistent wrap and precise fit.

C.A.S. Shell & N.F.S. Liner

Tecnica’s C.A.S. Shell uses an anatomical shape designed to match the contours of the foot. Its dimpled surface reduces material tension and makes the shell easier to thermoform and customise, while also helping it retain its customised shape over time.

Inside, the N.F.S. Adaptive liner combines anatomically pre-shaped padding with extra-thick, soft cushioning. The liner can also be thermoformed using hot air for further fit refinement.

Fit & Performance

With a 103 mm last and HV volume, the Mach BOA HV 100 is particularly suited to skiers with wider feet or those who find conventional medium-volume boots too restrictive. Its 100 flex offers a useful middle ground between support and ease of flex, making it appropriate for intermediate through expert recreational skiers.

The combination of BOA precision, C.A.S. customisation and GripWalk soles makes the boot equally well suited to groomed pistes and broader all-mountain resort use.
