The Dual BOA H+i1 Fit System uses two independent dials — a cuff pull and a shell pull — to wrap the leg and foot from cuff to shell for a dialed-in fit. Each dial provides micro-adjustable tension independently, allowing the skier to tune cuff pressure and foot pressure separately without removing gloves. The Mimic Platinum liner adds a heat-moldable layer at the heel, ankle, and tongue: after oven softening, the liner material conforms to the precise shape of the skier's foot and hardens in that shape, creating a custom interface that reduces internal movement. Memory Fit extends this customization to the shell and cuff itself, allowing full heat-reshaping to the skier's leg and foot geometry. The AFS Cuff spoiler adds volume adjustment for different calf shapes.

The HAWX Prime 120 S Dual BOA is built for strong all-mountain skiers on piste and variable terrain. The 120 flex provides the stiffness that aggressive skiing demands, and the Prolite construction with Energy Backbone reinforcement delivers the torsional rigidity needed for confident edge-to-edge response. Power Shift 2.0 allows independent forward lean adjustment at 13°, 15°, or 17°, and a flex shim system for fine-tuning — a level of on-snow adjustability that most performance boots at this price point do not offer. The Gripwalk sole adds off-snow mobility without compromising binding compatibility.

The 100mm last is medium volume — wider than the Nordica Promachine 3 120's 98mm narrow last — and designed to fit most skiers right out of the box without bootfitter intervention. The Mimic Platinum liner provides a firm, supportive fit with cushioning and a high level of customization through the Mimic heat-molding process. Memory Fit shell and cuff customization, the AFS Cuff spoiler for calf volume adjustment, and Power Shift 2.0 forward lean adjustment give the HAWX Prime 120 S a broader fit accommodation range than most fixed-geometry performance boots. Skiers with medium-volume feet will find the 100mm last an immediate, comfortable match.
