Salomon S/Pro Supra Boa 110 Ski Boots 2026/27

The S/Pro Supra Boa 110 is a medium-stiffness all-mountain boot built for advanced skiers who want control without maximum rigidity. The standout feature is the BOA Fit System dial on the lower shell, letting you fine-tune pressure and wrapping in seconds as conditions and fatigue change through your day.

Why we rate it

The ExoWrap construction—a precision pairing of thin-walled shell and cushioned liner—wraps your foot evenly, killing pressure points and holding your heel and ankle with real authority. The Custom Shell HD polyurethane shell molds to your foot in ten minutes, personalizing the fit further. The 100 mm last sits comfortably between narrow and wide, suiting most foot shapes, and the flex feels smooth and progressive rather than harsh, so you can charge confidently without punishment on longer days.

Who it's for

Advanced skiers tackling all-mountain terrain on piste and variable snow, and intermediate-advanced skiers ready to push harder. The medium volume works well for average to slightly wider feet. The BOA dial suits anyone who values micro-adjustments and doesn't want a fixed-buckle commitment.

Fit and feel

The 100 mm last width and medium-volume liner suit average to slightly broader feet well. Flex at 110 is stiff enough to hold an edge and transmit power, but progressive enough that you're not fighting it all day. The Custom Shell HD takes heat-molding beautifully; many skiers add a liner mold too, using the Talyn material's workability for a truly personal feel. Heel hold is very secure thanks to the ExoWrap geometry and Power Spine rebound.

From the fitting room: If you're a strong intermediate or advanced skier considering whether 110 is enough, remember this isn't a race boot—it's engineered for all-mountain confidence. Most skiers in that bracket find 110 speaks clearly enough to the snow.
