The Tecnica Mach1 HV 110 men’s ski boots are engineered for skiers who demand a perfect blend of power, precision, and all-day comfort — especially those with wider feet seeking a high-volume fit without sacrificing control. With a 110 flex rating, these boots offer responsive performance ideal for advanced to expert skiers looking to charge hard on groomers and off-piste terrain alike. The high-volume (HV) shell provides extra room in the forefoot and instep, delivering comfort without compromising the dynamic response Tecnica is known for. Featuring Tecnica’s C.A.S. (Custom Adaptive Shape) technology, both the shell and liner are fully customizable for a personalized fit that locks your foot in place and reduces pressure points. The Power Wrap 3.0 cuff enhances lateral support, while the Cantable Oversized Pivot optimizes flex and power transmission for superior edge control. Inside, the C.A.S. Performance liner provides warmth, cushioning, and moisture management, making long days on the mountain more comfortable. A grippy sole ensures confident walking on icy surfaces and in ski boots.
