ROXA R/FIT MV 100 GW are an excellent choice for intermediate to advanced recreational skiers who seek a balance between sportiness and comfort.

Flex 100 – balanced stiffness for controlled skiing

Flex 100 denotes a mid-to-high level of boot stiffness, providing a good balance of support, responsiveness and comfort.

Compared to stiffer models Flex 120 or 130, it allows slightly easier bending of the boot, which is especially useful for recreational skiing and developing technique.

Main advantages

• Controlled energy transfer: efficient response of the ski to leg movement.

• Balanced stability: reliable support when turning.

• Easier bending: less effort when loading the front of the boot.

• Comfort: suitable for longer ski days.

• Versatility: a good choice for various recreational skiing styles.

Who is Flex 100 for?

The hardness 100 is mainly suitable for intermediate to advanced skiers who want a sportingly responsive boot but do not require an extremely stiff competition-grade construction.

Flex ratings between manufacturers are not perfectly standardized. The actual stiffness feel also depends on temperature, boot size, and the skier's physical characteristics.

BioFit CM 100–102 mm – individually adjustable fit

BioFit CM (Custom Moldable) is Roxa's shell-adjustment technology, allowing individual shaping of specific areas according to foot anatomy.

The model has mid-wide shell 100–102 mm, placing it in the MV – Medium Volume category.

BioFit CM technology advantages

• Individual shell customization.

• Better fit for various foot shapes.

• Ability to reduce local pressure points.

• More even foot support.

• Increased comfort during extended use.

Shell adjustment should be performed by a trained ski boot professional using proper equipment.

Next Gen Overlap – lightweight and stable two-piece construction

Next Gen Overlap is a modern two-piece ski boot construction developed using CAD design, 3D prototyping and advanced polymer materials.

The design provides an effective balance between stiffness, weight and anatomical fit.

Main advantages

• Efficient power transfer: stable connection between leg and ski.

• Strong support: reliable foot and ankle hold.

• Optimized construction: reduced unnecessary mass.

• Anatomic shape: better foot embrace.

• Predictable flex: even response when carving.

The outer shell and upper part of the boot are made from polyurethane (PU/PU), providing a suitable combination of stiffness and flexibility.

4D BioFit Liner – thermo-formable inner boot

4D BioFit Liner is an anatomically shaped inner boot that allows fitting to the foot’s shape and provides support, warmth and comfort.

In the ankle area it uses Ultralon EVA padding, which improves heel grip and helps reduce unwanted foot movement.

Main advantages

• Thermo-forming: inner boot can be adapted.

• Anatomical fit: better embrace of the foot and ankle.

• Ultralon EVA: lightweight and supportive padding.

• Heel stability: less unwanted movement inside the boot.

• Thermal comfort: more pleasant feel while skiing.

The 4D BioFit inner boot is intended for skiers who want comfort without unnecessarily reducing precision in guiding the skis.

WinTherm® – thermal insulation for cold days

WinTherm® is an insulating technology that helps keep feet warm during skiing.

It combines thin insulating felt fibers with an aluminum microfoil that reflects some heat back toward the foot.

WinTherm® insulation advantages

• Thermal protection: reduces heat loss.

• Heat reflection: aluminum microfoil contributes to insulation.

• Low weight: no unnecessary extra mass.

• Breathability: contributes to inner boot comfort.

• Comfort: suitable for all-day skiing in cooler weather.

Easy Entry System – easier donning and doffing

Easy Entry System is designed for easier opening of the shell top and simpler inserting and removing of the foot.

This feature is especially useful in colder temperatures when boot materials are typically stiffer.

Main advantages

• Easier boot putting on.

• Easier doffing after skiing.

• Less effort when opening the shell.

• Practical for cold conditions.

• More everyday comfort.

Trident Bi-Injected Cuff – stability and adaptability

Trident Bi-Injected Cuff is the boot’s upper part produced with a mixed-material injection technology.

Such construction enables optimization of stiffness and flexibility across different areas of the upper boot.

Trident construction advantages

• Stable support for the lower leg.

• Efficient energy transfer.

• Balanced flexibility.

• Better control when carving.

• More comfortable feel while skiing.

Opti Lock – more precise ankle buckle positioning

Opti Lock is a buckle adjustment system at the ankle that enables a choice between two positions.

This allows the skier to adjust pressure and grip according to the foot’s shape.

Opti Lock advantages

• Two buckle adjustment positions.

• Better ankle height accommodation.

• Sturdier foot hold.

• More even pressure distribution.

• More comfort and stability.

The model is equipped with four aluminum, micro-adjustable buckles that allow precise buckling.

GripWalk – more comfortable and stable walking

GripWalk (GW) is a outsole system with a profiled rubber walking surface and rounded shape, enabling a more natural foot motion while walking.

Main advantages

• Better grip: profiled rubber walking surface.

• More natural walking: easier transition from heel to toe.

• More comfort: more pleasant movement off the slopes.

• Practicality: suitable for walking to chairlifts and ski facilities.

• Compatibility: use with GripWalk-compatible bindings.

Important: Ski boots with GripWalk soles must be used with bindings that are GripWalk-compatible.

Technical data

Who would you recommend ROXA R/FIT MV 100 GW ski boots to?

ROXA R/FIT MV 100 GW we recommend to skiers who seek comfortable, stable and responsive ski boots for regular use on the slopes.

They are especially suitable for:

• Intermediate skiers who want to improve carving technique.

• Advanced recreational skiers who need good control.

• Skiers prioritizing comfort but requiring solid support.

• Carving enthusiasts seeking balanced energy transfer.

• All-mountain skiers who ski on various snow conditions.

Due to the adjustable flex, they are more suited for relaxed sport skiing than the very stiff models Flex 120 and 130.

How to correctly measure the foot?

1. Stand on a flat sheet of paper with your heel against the wall.

2. Weight-bear on the foot.

3. Mark the longest toe.

4. Measure the distance from heel to the mark.

5. Repeat on the other foot.

6. For size selection, consider the longer foot.

Size selection tip

With ski boots, the foot should be firmly seated and the heel stable.

In a upright position, the toes may touch the front of the inner boot slightly; in a proper skiing stance the pressure usually decreases.

Important: We recommend professional fitting and, if necessary, individual adjustments of the inner boot and shell.

Recommended use and adjustment

ROXA R/FIT MV 100 GW are designed for recreational and sport alpine skiing, carving turns and varied groomed ski areas.

For optimal fit we recommend:

1. Right size: choose based on foot length and width.

2. Appropriate ski socks: thin functional socks without wrinkles.

3. Precise buckling: evenly adjust all four buckles.

4. Thermo-forming: adjust the inner boot 4D BioFit as needed.

5. Professional bootfitting: adjust the BioFit shell when needed.

Properly adjusted ski boots enable more efficient energy transfer, better control and greater comfort while skiing.

Maintenance and care of ski boots

To maintain functionality and long service life we recommend:

• After skiing, open the boots and ventilate.

• Remove and dry the inner boots if needed.

• Avoid drying them directly on a radiator or near strong heat sources.

• Regularly clean buckles and soles from snow and dirt.

• Check the wear of GripWalk soles.

• Before the season, check boot- binding compatibility.

• Store boots in a dry place.

• During long-term storage, slightly loosen the buckles to maintain shell shape.

Important: Thermo-forming of the inner boot and shell adjustment should be performed by a trained professional.
