2027 Salomon S/Pro Supra S BOA 110 Ski Boots

Single-BOA closure on the cuff and traditional buckles on the lower shell define the Salomon S/Pro Supra S BOA 110, an all-mountain boot that splits the difference between full-BOA and full-buckle constructions. A 100mm medium-volume last fits the broadest range of foot shapes in the S/Pro line, and the 110 flex sits in the sweet spot for strong intermediates and advancing advanced skiers who want power without the demands of a stiffer flex. ExoWrap shell construction adds the kind of even pressure distribution that's quietly transforming how all-mountain boots fit.

Why we like it:

The combination of buckle reliability on the lower shell and BOA precision on the cuff is the best-of-both-worlds story here; the lower shell still clamps like a traditional boot, while the cuff micro-adjusts in a way that buckles can't match.

Who it's for:

Strong advanced skiers and progressing advancing-intermediate skiers with medium-volume feet. The 100mm last works across the broadest range of foot shapes, and the 110 flex strikes a balance between manageable driveability and meaningful response. This is a strong choice for skiers stepping up from a softer flex who aren't quite ready for the full demands of a 120 or 130.

Highlights:

Polyurethane runs through both the shell and cuff, with ExoWrap construction and an embedded Sensifit Insert giving the lower shell its even pressure distribution. Closure runs through a BOA Fit System dial on the cuff plus two screwed aluminum buckles on the lower shell, with a 45mm screwed Velcro power strap finishing the top. The heat-moldable S/Pro CF Expert liner inside delivers Talyn-reinforced foothold and snug heel retention atop a Light² Footbed. GripWalk soles come premounted (ISO 5355), and a screwed cuff alignment pivot lets a fitter dial in stance.

Things to consider:

Skiers wanting maximum stiffness or expert-level response should step up to the 120 or 130 in this line. The cuff BOA takes a moment to dial in compared to a traditional buckle; experienced skiers used to a cam-lever feel should give it a few runs before judging.

Fit & sizing considerations:

A 100mm last sits in medium-volume territory and accommodates most foot shapes. Standard mondopoint sizing applies. A proper fitting session is worth booking for any boot at this flex level to lock in heel hold and shell shape.
