Two BOA dials and a roomier 100mm last define the Salomon S/Pro Supra Dual BOA 105 W, a women's all-mountain boot built for skiers who want precision fit and a comfort-leaning volume. The dual-dial closure replaces traditional buckles entirely, with one BOA handling the cuff and one handling the lower shell wrap. ExoWrap shell construction adds even pressure distribution across the foot, making this one of the more uniformly snug boots in the women's performance category.

Why we like it:

The lower BOA dial micro-adjusts forefoot and instep wrap in a way that buckles simply can't match; if your foot has ever felt too tight at the instep but too loose at the toe in a traditional buckled boot, this closure system is going to feel revelatory.

Who it's for:

Advanced women skiers with medium-volume feet who want serious power transmission without giving up day-long comfort. The 100mm last is medium-volume, so this works for the broadest range of women's foot shapes. The 105 flex hits a sweet spot for strong skiers who don't want to commit to the workload of a 115.

Highlights:

Polyurethane runs through both the shell and cuff here, with ExoWrap construction on both pieces and an embedded Sensifit Insert in the lower shell for added structure. Two BOA Fit System dials handle all closure duties, replacing traditional buckles entirely; the lower dial wraps the forefoot and instep, while the upper dial micro-adjusts cuff tension. A 45mm screwed Velcro power strap finishes the top. Liner duties go to the heat-moldable S/Pro CF Expert with Light² Footbed and Talyn construction, shaped to a women's-specific cuff. The sole is GripWalk premounted (ISO 5355), and screwed cuff alignment gives a fitter standard adjustment options.

Things to consider:

BOA dials require dexterity to operate with thick gloves, so skiers who frequently ski in deep cold should test-drive the closure system before committing. Skiers who like the satisfying clamp of buckles may take a session or two to adjust to the dial feel.

Fit & sizing considerations:

A 100mm last is medium-volume and works for the majority of women's foot shapes. Standard mondopoint sizing applies. With a 105 flex, a proper fitting session is worth the time; the Custom Shell HD process can deliver real shell modifications if needed.
