Built for women who want equal parts precision and comfort, the Salomon S/Pro Dual BOA® 105 brings a new level of micro-adjustable performance to the all-mountain category. With dual BOA® dials working in tandem—one on the cuff and one on the lower shell—these boots lock in a custom wrap that adapts perfectly to the unique shape of your foot. The result? Confident control, seamless energy transfer, and all-day comfort no matter the terrain.
The Power Spine steel reinforcement connects cuff and shell, giving every turn progressive rebound and reliable forward flex in changing snow conditions. A Custom Shell™ HD heat-moldable design allows both cuff and lower shell to be tailored in minutes, while SensiFit™ mesh makes entry effortless and enhances the snug, wrapped-in feel once the boots are buckled. For women-specific fit, the cuff is sculpted with lower rear support for added comfort around the calves without giving up leverage or precision.
Inside, the My Exowrap™ 4D Perf liner features latex-foam layering, an elastic forefoot belt, and Exowrap™ construction that keeps your foot planted and steering sharp. The Light² footbed reduces weight without sacrificing stability, and the customizable tongue lets you fine-tune instep height by adding or removing material. Add in the 45mm Energizer strap with Velcro for rebound and hold, and you’ve got a boot that keeps up with aggressive skiing while staying versatile enough for long days on snow.
On the ground, the GripWalk pads deliver sure-footed traction across ice, rock, and parking lots. And with screw-mounted hardware throughout, these boots are not just performance-driven—they’re serviceable and built to last season after season.

Skier Level: Advanced
Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.
This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Conversions are approximate and can differ by half a size between brands.
Half Sizes
Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.
Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
