Double down on fit is the pitch behind the Salomon S/Pro Supra Dual BOA 120, and it delivers exactly that. Two BOA dials replace the entire buckle system, with one handling cuff tension and one handling the lower shell wrap, while a 100mm medium-volume last keeps the fit accessible for a wide range of foot shapes. The 120 flex sits in the sweet spot for advanced skiers who want real performance without the demands of a true expert-level boot.

Why we like it:

Lower-shell BOA is the headline tech; very few boots offer micro-adjustability across the forefoot and instep, and this closure makes pressure tuning across the whole foot something a skier can do mid-run without taking the boot off.

Who it's for:

Strong advanced skiers with medium-volume feet who want micro-adjustable fit precision in an accessible flex. The 120 sits below the flagship 130 but above mid-flex options like the 100, making it the sweet spot for skiers who ski hard but don't push race-level edges every run. The 100mm last accommodates the broadest range of foot shapes in the S/Pro line.

Highlights:

The polyurethane shell carries ExoWrap reinforcement and an embedded Sensifit Insert so the Supra Dual BOA 120 wraps the foot evenly, thanks to the two-dial closure replacing all four buckles. The polyurethane ExoWrap cuff ties directly into the lower-shell construction for unified flex behavior. Salomon packs in the heat-moldable S/Pro CF Expert liner with Light² Footbed and Talyn-reinforced foothold. The 45mm screwed Energyzer Velcro power strap finishes the top. GripWalk soles come factory-mounted to ISO 5355. Screwed cuff alignment plus a premounted 6mm back spoiler open up meaningful adjustment options for a fitter.

Things to consider:

The Dual BOA closure is genuinely different from a buckle system and takes some adjustment for skiers used to clamp-style tightening. Deep-cold operation with bulky gloves can be tricky on the dials. Skiers chasing maximum stiffness should step up to the 130.

Fit & sizing considerations:

Medium-volume foot shape is the target here; the 100mm last works for the majority of skiers. Stick with your usual mondopoint size. For any 120-flex boot, time spent with an experienced bootfitter pays off in heel hold, shell shape, and stance alignment.
