What Our Gearhead(R) Experts Are Saying: "I've skied Hawx boots for years, and the Ultra 100 Dual BOA hits the sweet spot between comfort and control. The BOA on the cuff dials in a snug fit around my narrow ankles, and the heat-moldable shell makes it feel fully custom. Great for all-day laps when I don't want to compromise on performance or fit." Comfort and control shouldn't be trade-offs-and with the Atomic Hawx Ultra 100 Dual BOA Ski Boot, they're not. Designed with Atomic's signature narrow fit and a medium 100 flex, this boot caters to skiers who want performance-driven precision with all-day comfort, especially those with slim ankles or low-volume feet. The Dual BOA system wraps both the lower foot and cuff evenly for easy, micro-adjustable fit on the fly. Paired with Atomic's heat-moldable Memory Fit shell and 3D Silver liner, the Hawx Ultra 100 Dual BOA achieves a near-custom feel with excellent heel hold and adaptable volume. The Adaptive Fit Cuff System lets you fine-tune the upper cuff to your calf shape without tools, and Prolite construction adds reinforcement only where it's needed, keeping the boot light yet powerful. For intermediate to advanced skiers looking for fit-first performance, this is a boot that truly delivers.
