For women who want one boot that can climb efficiently and then hammer down the fall line, the Salomon Shift Alpha BOA 115 delivers the perfect balance of uphill freedom and downhill authority. Born from freeride DNA and reinforced with alpine strength, this boot is built for serious terrain and serious skiers.
The FreeSpine™ system ties the cuff and lower shell together, giving you dependable flex and control when it’s time to drive the ski. On the uphill, the Twinlock mechanism unlocks a generous range of motion, while the PowerWedge and Frictionless pivots make each stride more efficient. When the line calls, lock it back in and unleash all the stiffness and stability of a true alpine charger.
Fit is where the Shift Alpha BOA 115 really shines. The BOA Fit System, paired with Salomon’s Exobelt™ closure, dials in micro-adjustments for a snug, blister-free hold that keeps your heel locked down and power transmission razor sharp. Inside, the My Custom Fit™ Freeride 4D Pro liner wraps the foot with cushioned foams and customizable zones, while the elastic toe box relieves pressure without sacrificing control. A women’s-specific cuff design adds comfort around the calves without taking away support.
Durability and versatility finish the package: a polyurethane shell with Custom Shell™ HD heat molding, integrated tech inserts for touring bindings, and a Contagrip® midgrip sole with GripWalk pads that digs in on rocky ridges, icy bootpacks, or slick parking lots. With replaceable buckles, pivots, and soles, this boot is engineered to last season after season.

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.

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.
