ROXA RJ 70 ALPINE Kids Ski Boots

Kids and Youth Ski Boots ROXA RJ 70 ALPINE – Flex 70 hardness, stable Next Gen Overlap two-piece construction, four aluminum buckles, BioFit 102 mm anatomically shaped shell and comfortable Junior Comfort inner boot

ROXA RJ 70 ALPINE are sport-inspired youth ski boots from the Italian manufacturer ROXA, intended for young skiers who have already mastered basic skiing technique and are seeking more stability, precision, and control on the slopes.

The RJ 70 ALPINE model combines Flex 70 hardness, modern two-piece Next Gen Overlap construction, anatomically shaped BioFit 102 mm shell, and four aluminum buckles, enabling firm yet adaptable fastening.

For comfort, an inner boot Junior Comfort Liner is provided, developed specifically for young skiers. It provides comfortable padding, foot support, and thermal comfort during winter activities.

A feature of the model is also BioFit CM, a technology that allows expert adjustment of the outer shell to the shape of the foot. The ALPINE variant is equipped with a classic alpine outsole designed for use with appropriate alpine ski bindings.

ROXA RJ 70 ALPINE are an excellent choice for young recreational and competitive skiers who need a reliable, comfortable, and responsive ski boot for further development of skiing technique.

Flex 70 – Sport support for young skiers

Flex 70 denotes the stiffness level of the ski boot, enabling more efficient energy transfer and a firmer support during skiing.

Compared to softer kids’ models, RJ 70 is mainly for older children and teenagers who already ski independently and want more precise guidance of the skis.

Main advantages

• Stable support: firmer hold of the foot and ankle.

• More accurate control: more effective transfer of movement to the skis.

• Sport readiness: suitable for developing more demanding techniques.

• Controlled flex: predictable feel when turning.

• Versatility: usable for both recreational and sport skiing.

Who is Flex 70 for?

The hardness 70 is especially suitable for young skiers with developed basic technique who need more support than beginner children's boots.

The choice of appropriate stiffness depends on body weight, strength, skill, and skiing style.

Important: Flex markings are not fully standardized across manufacturers. A child’s ski boot should not be excessively stiff relative to the child’s weight and abilities.

Next Gen Overlap – advanced two-piece construction

Next Gen Overlap is ROXA’s modern two-piece ski boot construction designed for stability, precision, and efficient use of materials.

In developing the construction, the manufacturer uses advanced computer-aided design CAD and 3D prototyping technology.

Key advantages

• Stability: firm support of the foot and lower leg.

• Accurate energy transfer: more direct response of the ski.

• Optimized construction: efficient balance between mass and strength.

• Anatomical shaping: better fit to the foot.

• Predictable performance: even feel while skiing.

The two-piece design is suitable for young skiers who need reliable support while learning more demanding skiing movements.

BioFit 102 mm – anatomically shaped shell

BioFit is ROXA’s shell design aimed at comfortable and stable foot fit.

The RJ 70 ALPINE model declares a shell width of 102 mm, which allows relatively roomy fit, and with the correct size selection provides proper support.

Key advantages

• Anatomical fit: design for comfortable foot placement.

• Stability: less undesired movement inside the boot.

• Comfort: reducing unnecessary pressure.

• Control: more effective contact between foot and boot.

• Adjustability: possibility of expert shell adjustment with BioFit CM technology.

Important: The 102 mm width is the nominal specification from the manufacturer. The actual boot width also depends on the chosen size, so try-ons are recommended.

BioFit CM – option for individual shell adjustment

BioFit CM (Custom Moldable) enables a trained ski boot technician to tailor the outer shell in areas where the foot needs extra space.

The technology is particularly useful when a young skier has sensitive areas or anatomical peculiarities of the feet.

Advantages

• Possibility to adjust the outer shell.

• Reduction of local pressures.

• Better individual fit.

• More comfort for extended use.

• Maintaining stable foot grip.

Adjustment must be performed by a qualified professional, as improper heating or shaping can damage the ski boot.

Junior Comfort Liner – comfortable inner boot for young skiers

Junior Comfort Liner is the inner boot developed specifically for ROXA children’s and youth models.

Its design combines comfortable padding, proper support, and thermal protection for use in winter conditions.

Main advantages

• Comfortable padding: a more pleasant skiing feel.

• Thermal comfort: helps keep feet warm.

• Anatomical fit: designed for young skiers.

• Foot stability: better grip inside the boot.

• All-day usability: suitable for ski courses, training, and recreational skiing.

The Junior Comfort liner helps create a balance between comfort and stability, which is important when developing skiing technique.

Štiri aluminijaste zaponke – stable and adjustable fastening

ROXA RJ 70 ALPINE has four aluminum buckles, allowing individual adjustment of grip on the foot and lower leg.

The four-buckle system helps distribute pressure more evenly and provides stability during skiing.

Main advantages

• Four buckles: more precise adjustment of grip.

• Aluminum construction: strong and durable.

• Heel stability: less unwanted foot movement.

• Adjustable fastening: customization to foot shape.

• Sport support: effective transfer of movement to the skis.

Buckles should be fastened firmly enough for stability, but not so tight that they cause pain, tingling, or circulation issues.

Alpine Sole – classic alpine sole for ski bindings

The ROXA RJ 70 ALPINE variant is equipped with a classic alpine sole.

This is intended for use with appropriate alpine ski bindings and ensures predictable contact between boot and binding.

Main advantages

• Classic alpine design: suitable for alpine skiing.

• Stable binding contact: efficient energy transfer.

• Accurate steering: direct connection between boot and ski.

• Practical use: suitable for ordinary ski slopes.

Important: The ALPINE variant is not the same as the GripWalk (GW) variant. Compatibility of ski boots with bindings must be checked by a qualified ski technician before use. If needed, bindings must also be professionally adjusted.

Technical data

Whom do we recommend ROXA RJ 70 ALPINE ski boots to?

ROXA RJ 70 ALPINE is recommended for young skiers who need more stable and responsive ski boots for further technique development.

Particularly suitable for:

• Young recreational skiers who already master basic turns independently.

• Advanced kids who want more stability while skiing.

• Youth skiers developing carving technique.

• Participants in ski courses and training who need reliable equipment.

• Young athletic skiers who want more efficient energy transfer.

• Children and adolescents needing adaptable shell, with appropriate professional fitting.

Due to the Flex 70 stiffness, the model is not primarily for the youngest beginners, but for young skiers who already need more support and accuracy.

How to properly measure a child’s foot?

1. Have the child stand on a flat sheet of paper with the heel against the wall.

2. The foot should bear weight.

3. Mark the longest toe.

4. Measure the distance from the heel to the mark.

5. Repeat on the other foot.

6. When choosing size, consider the longer foot.

Size selection tips

A child’s ski boot should securely hold the foot, but must not cause pain or excessive pressure.

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

Important: It is not recommended to buy children’s ski boots significantly too large to accommodate growth. An oversized boot reduces stability and control of the skis.

Recommended use and fitting

ROXA RJ 70 ALPINE are designed for youth alpine skiing on groomed slopes, recreational sport, and developing skiing technique.

For optimal fit we recommend:

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

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

3. Even fastening: properly adjust all four buckles.

4. Check heel stability: the foot should not move excessively.

5. Professional adjustment: adjust BioFit CM shell if needed.

6. Check bindings: proper adjustment and compatibility with the alpine sole.

Properly fitted ski boots enable better control, more effective learning, and greater comfort for young skiers.

Maintenance and care of ski boots

For long life we recommend:

• After skiing, open the boots and ventilate.

• Remove and dry the inner boots if needed.

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

• Regularly clean buckles and soles from snow and dirt.

• Regularly check buckle and sole condition.

• Before the season, check binding settings.

• Store boots in a dry place.

• When storing for long periods, slightly tighten the buckles to keep the shell shape.

Important: Due to growth of children’s feet, it is recommended to re-check size suitability before each ski season.
