NORDICA Speedmachine 3 105 W BOA DD GW
Premium women’s all-mountain ski boots with a sporty character, flex 105, a 100 mm last and a BOA® Dual Dial system, combining high levels of control, comfort and extensive customization options. This model is primarily designed for experienced and performance-oriented female skiers who want a precise boot for all-day skiing across the entire mountain, but do not require the higher stiffness of the Speedmachine 3 115 W BOA DD GW.
The Nordica Speedmachine 3 105 W BOA DD GW is built around a women-specific anatomical fit and a dual BOA® system that allows more precise adjustment of the boot’s wrap across multiple zones. Nordica also redesigned its Tri Force construction to work optimally with the BOA® Fit System and maximize energy transmission between the foot, boot and ski. The result is intended to be efficient power transfer, precise control and stable foot positioning during performance-oriented skiing.
The 105 flex offers an excellent balance between support and comfort. It is stiff enough for dynamic skiing and precise ski control, yet remains more accessible and less demanding than a 115 flex. The 3D Cork Fit W Primaloft® liner, Bimat PU construction, 45 mm Power Strap, GripWalk Extra-Grip sole and customization options through Tri-Fit Technology and Infrared create a highly versatile performance boot for skiers who want strong performance without an unnecessarily race-oriented feel.
Who are these ski boots for?
The Nordica Speedmachine 3 105 W BOA DD GW is designed for sport and experienced female skiers looking for a versatile all-mountain boot for active skiing on groomed slopes as well as in changing conditions across the mountain.
A flex of 105 already provides substantial support, but compared with stiffer performance models it remains more accessible. This makes the boot suitable for skiers who want a more precise and sport-oriented response while still valuing comfort during longer days on snow.
This model is suitable for skiers who:
- ski with a sporty and technically confident style
- have a good to very good skiing level
- want a versatile all-mountain ski boot
- are looking for a 105 flex as a balance between performance and comfort
- prefer a medium 100 mm last
- want precise adjustment through BOA® Dual Dial
- require stable foot positioning
- want efficient energy transmission into the skis
- appreciate individual bootfitting possibilities
- need a boot suitable for all-day performance skiing
How do the boots perform on snow?
The Speedmachine 3 105 W BOA DD GW is designed to provide quick response, good control and efficient energy transfer without feeling excessively stiff or demanding.
The 105 flex creates a firm performance platform when the shell is loaded and helps maintain stability at higher speeds, through carved turns and during dynamic edge-to-edge transitions. At the same time, it is more forgiving than a 115 flex, so the boot is not reserved only for highly aggressive or physically strong skiers.
An important element is the redesigned Tri Force Construction, which Nordica has optimized to work with the BOA® Fit System. The goal is to maximize energy transmission and increase power, efficiency and control.
Two BOA® dials allow fine adjustment of the boot’s wrap and more precise tuning of different fit zones according to the skier’s needs. This helps create more stable contact between the foot, liner and shell without simply overtightening the boot.
On snow, you can expect:
- sporty support from the 105 flex
- quick and predictable response
- efficient power transfer into the skis
- good control during dynamic skiing
- stable foot positioning
- more precise wrapping thanks to BOA® Dual Dial
- versatile performance in different conditions
- enough support for performance skiing
- greater accessibility than stiffer 115-flex models
- a strong balance between performance and all-day comfort
How to understand the parameters
Flex index 105
The exact flex index of this model is 105.
Flex indicates the approximate stiffness of a ski boot when the skier presses the shin forward against the cuff. A higher value generally means greater shell resistance, stronger support and more direct transfer of the skier’s movements into the skis.
A flex of 105 sits in the performance category. It is suitable for skiers who want a firmer boot for active skiing but do not need or want the stiffness of models with flex 115 or higher.
In practice, flex 105 offers:
- good shin support
- more precise pressure transfer into the ski
- sufficient stiffness for performance skiing
- stability at higher speeds
- quick response to changing loads
- greater comfort than significantly stiffer models
Flex ratings are not completely standardized between manufacturers. Perceived stiffness can vary depending on boot construction, size, temperature and the skier’s physical characteristics.
100 mm last
The Speedmachine 3 105 W BOA DD GW has a stated 100 mm last.
This is a medium-width fit that creates a good balance between performance precision and comfort. It is not as narrow as typical race or LV models, but it is intended to provide more precise foot retention than comfort-focused high-volume boots.
During performance skiing, it is important that the foot does not move excessively inside the boot. Too much space reduces precision, while the correct width helps make better use of both the shell and flex.
The BOA® Dual Dial system and the available customization options make it possible to fine-tune the fit so the boot wraps the foot precisely while still remaining comfortable during longer ski days.
Technologies
BOA® FIT SYSTEM
The BOA® FIT SYSTEM allows precise adjustment of the boot’s wrap through a dial-based closure and cable routing system.
Compared with conventional point-based tightening, tension can be regulated much more precisely. The aim is not simply to make the boot as tight as possible, but to create a more even and stable hold around the foot.
Key benefits include:
- precise micro-adjustment
- more even pressure distribution
- easy tension regulation
- more stable foot retention
- more precise contact between foot and shell
- support for efficient movement transmission
For this model, the manufacturer also specifically states the use of a Dual Dial system, meaning two BOA® dials that further expand the adjustment possibilities across individual fit zones.
Easy Entry Soft Flap
The Easy Entry Soft Flap technology makes it easier to get into and out of the performance-oriented shell.
The entry area is designed to open more easily while putting the boot on. This is particularly useful in cold temperatures when shell materials naturally become stiffer.
Benefits include:
- easier entry
- easier removal
- more convenient handling
- less effort when putting the boot on
Infrared
Infrared technology expands the possibilities for professional shell customization according to the anatomy of the skier’s foot.
If excessive pressure develops in a specific area, a bootfitter can locally modify the relevant section of the shell. This avoids the need to enlarge the entire boot or lose precision in zones where the fit is already correct.
The technology allows:
- treatment of specific pressure points
- localized shell modification
- improved comfort
- preservation of precision in unaffected zones
- a more individualized fit
Strap 45mm
The model uses a 45 mm Power Strap that complements the closure of the upper section of the boot.
The wide strap helps stabilize contact between the shin and cuff and supports efficient movement transfer during active skiing.
Benefits include:
- firmer shin-to-cuff contact
- greater stability in the upper section
- added support under dynamic loads
- more precise power transfer into the shell
Tri Force Construction
The Tri Force Construction uses different characteristics in individual shell zones so the boot can combine support, power transfer and comfort.
Rather than making the entire shell equally stiff, the construction uses functional zones depending on the role each area needs to perform.
For this model, Nordica specifically redesigned Tri Force to work with the BOA® Fit System. The manufacturer states that the aim is to maximize energy transmission for greater power, efficiency and control.
In practice, the technology contributes to:
- efficient energy transfer
- quick boot response
- precise ski control
- functional distribution of stiffness
- stable connection between the foot and shell
- a balance between performance and comfort
Tri-Fit Technology
Tri-Fit Technology focuses on individual customization of the ski boot.
It allows the shell and liner to be better matched to the anatomy of the individual foot and helps create a more personalized fit according to the skier’s needs.
The aim is to optimize:
- foot retention
- comfort
- energy transfer
- control precision
- long-term functionality of the fit
With a performance boot in the 105-flex range, correct fit is particularly important. The boot needs to be firm enough for precise ski control while avoiding unnecessary pressure points.
Shell construction
The Speedmachine 3 105 W BOA DD GW uses Bimat PU for both the shell and cuff.
The construction is designed for performance all-mountain use and combines the support of a 105 flex with the precise BOA® system and individual customization possibilities.
Technical construction includes:
- Bimat PU shell
- Bimat PU cuff
- flex index 105
- 100 mm last
- Tri Force Construction
- BOA® Dual Dial
- customization possibilities through Infrared
- Forward Lean Shell Rotation 12°
- 45 mm Power Strap
The result is a performance-oriented construction that is not excessively race-focused, but still provides enough support for an experienced skier and active skiing across the mountain.
3D Cork Fit W Primaloft® liner
The model is equipped with a 3D Cork Fit W Primaloft® liner.
Its construction combines precise foot retention, individual customization and thermal comfort. Cork elements support stable foot positioning and anatomical adaptation, while Primaloft® contributes to a warmer and more comfortable environment inside the boot.
The liner supports:
- precise anatomical foot positioning
- stable foot retention
- individual customization
- improved connection between foot and shell
- thermal comfort
- comfortable all-day use
- performance-oriented control
A correctly fitted liner is also important from a performance perspective. The more securely the foot is positioned, the more efficiently the skier’s movements can be transferred into the shell and subsequently into the skis.
BOA® Dual Dial Fit System
Although the technical specification uses the general term BOA® Fit System, the manufacturer explicitly states that this particular model uses the Dual Dial Fit System from BOA®.
The boot therefore uses two BOA® dials, allowing more precise control over the wrap of multiple fit zones.
The dual-dial configuration provides:
- more precise fit adjustment
- finer control of individual sections
- more stable retention of the foot and lower leg
- more even pressure distribution
- quick tuning during the ski day
- more anatomical overall wrapping
Another important element is the integration of BOA® with the redesigned Tri Force construction. Nordica did not simply change the closure system; the shell itself was also redesigned so both elements can work together to support more efficient energy transmission and precise control.
45 mm Power Strap
The upper part of the boot is complemented by a 45 mm Power Strap.
The wide strap helps maintain stable contact between the shin and cuff and provides additional support when the skier actively drives forward.
In practice, it complements the BOA® system and contributes to:
- greater upper-boot stability
- improved shin contact
- more efficient movement transfer
- more confident ski control
GripWalk Extra-Grip
The technical description specifies a Gripwalk Extra-Grip sole.
GripWalk® is designed for more comfortable and natural walking when the skis are off. The profile and shape of the sole help when moving between the car park and lift, around mountain restaurants or throughout the ski resort.
Benefits include:
- more comfortable walking without skis
- more natural foot roll
- more practical movement on winter surfaces
- greater convenience during the ski day
For correct use, the boots must be paired with ski bindings compatible with GripWalk® soles.
