Flex: 105

With a flex index of 105, this Salomon women’s ski boot offers firm, sporty support. The boot responds instantly to your movements and provides sufficient resistance for powerful turns, active carving, and controlled skiing at higher speeds.

The Power Spine supports a progressive forward flex and a responsive rebound. This relatively stiff construction is particularly well-suited for female skiers who have the technique and strength to actively engage the boot.

Fit & Last Width: Medium Volume – 100 mm

The S/Pro Supra Dual BOA 105 W has a medium fit with a nominal last width of 100 mm. Salomon specifies a size-specific width range of 100 to 106 mm.

The ExoWrap construction works in conjunction with the lower BOA Fit System to precisely wrap around the forefoot. The separate BOA closure on the cuff allows for independent adjustment of the support around the lower leg.

This medium last is particularly well-suited for female skiers with an average foot width who are looking for a firm, performance-oriented fit. The instep height, heel shape, and overall foot volume also determine how well the boot fits.

Closure System: Dual BOA Fit System

The Dual BOA Fit System is the most striking feature of this ski boot. Two separate dials replace the traditional buckles and allow for precise adjustment of the lower shell and the cuff.

The lower BOA controls the fit around the forefoot and instep, while the upper BOA determines the tension around the lower leg. This allows you to adjust both zones independently and further refine the pressure distribution.

A 45 mm Screwed Velcro Power Strap provides extra support at the top of the cuff and aids in power transfer while skiing.

Liner & Footbed: S/Pro CF Expert 4D

The S/Pro CF Expert 4D liner features an anatomically contoured construction with supportive foam layers and Talyn material for targeted fit adjustments.

The thermoformable liner helps provide precise support for the foot and ankle, while the elastic toe box offers extra room for movement. Thanks to the removable Custom Tongue, the fit across the instep can also be customized.

The lightweight Light² Footbed provides the foundation for underfoot support.

Shell & Cuff: ExoWrap & Power Spine

The polyurethane shell and cuff combine a firm, progressive flex with efficient power transfer. Thanks to ExoWrap, the outer shell, inner boot, and both BOA closures work together to provide a precise fit.

The Power Spine connects the cuff to the shell and supports forward flex and rebound during dynamic turns. The sensiFIT insert makes it easier to step into the boot and conforms to the anatomical shape of the instep.

With Custom Shell HD, specific areas of the shell and cuff can be professionally thermo-molded. The bolt-on Cuff Alignment Pivot also offers options for fine-tuning the cuff’s alignment.

Sole & Binding Compatibility: GripWalk

The pre-mounted GripWalk soles comply with the ISO 23223 standard. They offer extra grip and a more natural rolling motion when walking off-piste.

These ski boots are compatible with ski bindings that are explicitly compatible with GripWalk. Not every traditional alpine binding supports this sole standard. Therefore, always have the compatibility of your specific binding checked and have the binding professionally adjusted.

Level: Advanced – Expert

These Salomon ski boots are designed for advanced to highly experienced female skiers who enjoy powerful and dynamic skiing. The 105 flex provides firm support for aggressive turns, higher speeds, and technically challenging slopes.

An interesting choice for those who value responsiveness and want to be able to adjust the fit around the foot and lower leg separately. For relaxed recreational skiing, this stiffer construction may be less suitable.

Size Guide: Mondopoint & Fit

Choose your ski boot based on your foot length in centimeters, expressed in Mondopoint. Your regular European shoe size is only a guideline.

With this medium Supra fit, your forefoot width, instep height, heel volume, and calf shape are also important. The boot should fit snugly with a stable heel and sufficient support around the ankle. A ski boot that’s too large can cause extra movement of your foot and reduce control while skiing.

Stoked Boot Fitting Advice

Thanks to Dual BOA, Custom Shell HD, the adjustable S/Pro CF Expert 4D liner, and optional supportive insoles, we can specifically optimize the fit wherever the construction and your foot shape allow.
