Built for strong skiers with wider feet, the Mach BOA HV 105 W GW delivers a blend of power and comfort that suits long days lapping the mountain and hunting for soft snow. The women’s-specific, high-volume 103 mm shell works with the BOA Fit System on the lower boot to create an even wrap over the midfoot, boosting heel hold without crushing sensitive spots. A 105 flex and PU C.A.S. shell give you solid, progressive support for carving on firm snow, while the Double Quick Instep keeps entry and exit straightforward, even on cold mornings. Inside, the Ecodesign Sport N.F.S. liner with Celliant insulation offers a close, warm fit that can be customised by a good bootfitter to really dial things in. Finished with GripWalk soles and a 35 mm power strap, it’s a modern, resort-focused boot for women who ski with intent but still value day-long comfort.
