The Tecnica Mach BOA MV 120 Ski Boot is built for strong, advanced skiers who want serious downhill performance with a fit they can dial in turn by turn. Its medium-volume anatomical shell is designed specifically around the BOA® Fit System, creating a precise, even wrap around the foot with micro-adjustable tension, strong heel hold, and fewer pressure points than a traditional lower buckle setup. Tecnica’s T-Sport system connects the cuff and lower shell to drive power toward the forefoot, giving the boot a responsive, energetic flex when you’re carving hard and picking up speed. C.A.S. shell and liner construction provide an excellent anatomical fit out of the box with extensive customization potential, while Quick Instep and Lift Lock buckles make getting in and out noticeably easier. Powerful, precise, and surprisingly comfortable for a 120-flex performance ski boot, the Mach BOA MV 120 is ready to get dialed in, locked in, and rip from first chair to last.

T-Sport

Inspired by Tecnica’s T-Drive technology, T-Sport creates a performance bridge between the upper cuff and lower shell. This strategic connection enhances power transmission toward the forefoot, helping deliver greater precision and control while maintaining shell integrity and a consistent, responsive flex.

BOA® Fit System

The BOA® Fit System provides a micro-adjustable performance fit engineered to improve feel and responsiveness while reducing pressure points. Precise adjustment creates a uniform wrap around the foot for strong heel hold, edge-to-edge control, and a secure connection between the skier and boot.

C.A.S. Liner

The anatomically shaped C.A.S. liner provides a precise fit, strong heel hold, and excellent comfort straight out of the box. Dual-density, pre-shaped thermoformed microcell material can be customized by a bootfitter and is designed to resist packing out, helping the liner maintain its performance fit over time.

C.A.S. Shell

The C.A.S. shell uses an anatomical shape that closely follows the foot for a more precise initial fit. Distinctive dimples reduce surface tension and make the shell easier to heat and customize, while helping it retain the customized shape longer.

Quick Instep

Quick Instep strategically uses softer plastic over the instep area, allowing the shell to open more easily when entering or exiting the boot without compromising the performance-oriented structure surrounding the foot.

Lift Lock Buckles

Tecnica’s Lift Lock system holds the buckles up and away from the shell while the boot is open, preventing them from catching as you step in or out and making the entire process quicker and easier.

Eco Design & Material Traceability

Tecnica’s material traceability program identifies the materials used in the boot to support more precise regeneration and reuse. This approach helps increase the potential for regenerated materials with consistent mechanical characteristics to be incorporated into future ski boot production.
