You ski the whole mountain and you are tired of boots that either crush your foot or leave it swimming. The Mach1 LV 105 W is built for narrow-footed women who want performance without paying for it in comfort.

The 98mm C.A.S. shell and women's-specific liner fit well straight out of the box, and the rear T-Drive 2.0 system gives a smooth, progressive flex that transmits power without making your quads do the work. It is the boot that lets you keep lapping instead of calling it at two o'clock.

What you'll love on the hill

• T-Drive 2.0 makes power transfer effortless and consistent, so hot laps burn the clock instead of your legs.
• The 98mm low-volume last holds a narrow foot properly, which means real edge control instead of cranked-down buckles.
• W.S.D. cuff and liner are shaped for a woman's lower leg, so the boot closes around your calf rather than pinching it.
• C.A.S. shell and liner are both heat-mouldable, so a bootfitter can fix hot spots properly.
• Celliant liner turns your own body heat back into warmth on cold chairlift rides.
• Quick Instep and Lift Lock buckles make getting in and out easy, even with cold hands.

Fit note: LV means low volume - a 98mm last for narrow feet and lower arches. If your forefoot is wide or your instep is high, the Mach1 MV 105 W (100mm) is the better starting point. Sizes are Mondopoint, the length of your foot in centimetres, not a street shoe size.
