Intended use

Built for the boot - carbon, precision, and edge feel.

The Ski Ortho Pro is designed for performance and precision. It is ideal for advanced skiers who ski 20 to 100+ days a year, and works with stock liners as well as upgraded high-performance liners like Zip-Fit, Intuition foam, and custom foam-injected liners.

Same stability and arch alignment as the Ski model - with the polypropylene frame replaced by a carbon fiber shell for vastly improved energy transfer to the ski edge and a lightweight advantage.

01

Narrow boot boards, high-performance liners

Narrow finishing and a semi-shallow heel cup let the device seat correctly in ski boots - including Zip-Fit, Intuition, and custom foam-injected liners.

02

Alignment through the kinetic chain

Maintaining the arch in a neutral position aligns the ankles and hips - more efficient body movement and comfort in typically uncompromising ski boots.

03

Symptomatic feet & biomechanical pathology

Functional correction for advanced skiers managing moderate to advanced pathology, with a Myolite extension and Prolite cover underfoot.

FootID Pro scanning platform

Functional correction, congruent to the foot.

Built from a positive model of the patient's foot and modifiable at the clinician's discretion - scanned and ordered through FootID Pro.

Generic support vs Root congruent shape
The Root difference

Shape is everything.

What separates Root from generic sport insoles is the precise morphological shape captured from the patient's foot - held in the exact clinical position the clinician chose. No averaging. No guesswork.

The Ski Pro device is built from a positive model of the patient's foot and can be modified at the practitioner's discretion. This means every device fits the patient it was made for - not an approximation.

Digital shape
Default ✓

Modern Root

Width adjusted considering both borders. Default for all Root models.

Cast in plaster

Traditional Root

Justified to the lateral border. Used for specific clinical indications at practitioner discretion.

Modern Root shape process

  • Forefoot balanced to rearfoot - forefoot-to-rearfoot relationship is optimised as the first step in shape modification.
  • Fat pad expanded ~3mm - ensures the device fills the calcaneal contour precisely for the patient's heel.
  • Arch lowered ~3mm - creates optimal heel-to-arch-to-met-head geometry. Not applied to foam impressions.
  • Width tuned to both borders - medial and lateral widths considered together, giving a foundation that matches the patient's actual foot width.
Subtalar joint positions - neutral, pronated, supinated

*Subtalar joint neutral is found by palpating the talus head against the navicular. The neutral position can present many joint-on-joint and bone-on-bone relationships and varies from person to person. An everted or inverted calcaneus may be a neutral position for an individual person. Biomechanical evaluation required.

FootID Pro - Clinical alignment scanning

How you hold the foot is what we build.

Root is not just the orthotic - it's the clinician's positioning, captured and preserved in the device. After scanning, FootID Pro asks the questions no other lab asks.

After every scan, we need to know:

  • Was the subtalar joint held in neutral?
  • Was the midtarsal joint maximally pronated - loading the 5th metatarsal head?
  • Was the midtarsal joint maximally supinated - loading the 1st metatarsal head?
  • Was the forefoot brought perpendicular to the rearfoot?
  • Was a forefoot-to-rearfoot balance bisection achieved at 90° relative to the calcaneal bisection?

The positioning of those 19 joints in the foot is what gives us the shape.

CAD/CAM fabrication

  • Scan or cast captured - clinician captures foot morphology via FootID Pro, holding the subtalar joint in the chosen clinical position.
  • Shape modification applied - forefoot balanced to rearfoot, fat pad expanded, arch adjusted using Root's design process.
  • Technical staff review - every device reviewed against Traditional Root, Modern Root, Blake Inverted, or Accommodative principles.
  • Fabricated to the shape - the polypropylene frame and EVA post are fabricated to match the submitted shape precisely.

From scan to finished orthotic

How your patient's foot shape becomes a precision frame.

The journey from clinical capture to finished Ski Pro frame is where Root's expertise lives. Every step preserves the shape and position the clinician chose for that patient.

  • Foot impression captured - the clinician captures the foot using their preferred method. How the foot is held directly determines the congruency of the finished device.
  • Positive model created - the impression becomes a physical plaster model or a digital CAD/CAM model. Digital models are stored indefinitely for future pairs.
  • Root technicians modify the shape - every modification reviewed against the prescription. Rearfoot post, heel cup depth, and cover selection confirmed per patient.
  • Ski Pro frame fabricated - the rigid carbon shell is formed over the positive model and finished narrow for ski boots. A 55–65 Shore A EVA rearfoot post, Myolite extension, and Prolite top cover are applied, forefoot balanced to rearfoot.

Real-time control over shape, function, and fit.

FitFoot360 gives Root's technicians complete digital control over every dimension of the orthotic frame - in real time. What once required physical carving and guesswork is now precise, repeatable, and stored permanently for every patient.

Digital positive model

Stored indefinitely. Future pairs, replacements, or modifications can be fabricated from the exact same shape without a new impression.

Real-time shape modification

Root technicians control arch, heel, width, and postings directly in the software.

Every parameter visible

Heel cup depth, frame reinforcement, ray cut-outs, flanges, and more are set per patient, not per template.

Plaster and foam digitisation

Physical models can be digitised for permanent storage. Note: digitising may not perfectly replicate the intimate contours achieved when vacuum forming directly over plaster.

Construction

Built to their spec. Built for their foot.

Every parameter of the Ski Pro device is set to the individual patient - frame rigidity, rearfoot posting, heel cup depth, and covers are all chosen for that patient's anatomy, weight, and boot volume. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.

FRAME MATERIALRigid Carbon

A rigid carbon fiber shell, custom congruent to the foot model - vastly improved energy transfer to the ski edge at a fraction of the weight.

REARFOOT POST55–65 Shore A EVA

An EVA rearfoot post stabilizes the rearfoot in the clinician's prescribed position while absorbing the vibration of a hard race piste.

HEEL CUP6mm

Pressed from the patient's calcaneus, the semi-shallow heel cup controls inversion and eversion while fitting a narrow boot board.

FRAME FILLERNone

A clean carbon shell with no filler - keeping the device low-profile so it seats correctly inside a performance boot.

FINISHINGNarrow

Narrow finishing lets the device drop into ski boots with typically narrow boot boards - including high-performance and foam-injected liners.

DEVICE-LENGTH EXTENSION1.5mm Myolite

A heel-to-toe Myolite extension adds shock absorption and insulation across the full length of the device.

TOP COVER3mm Prolite

Proprietary Prolite padded top cover - moisture control, warmth, and cushioning underfoot through a full day on the mountain.

BOTTOM COVER0.6mm Suede

Biomechanics

Designed for energy transfer and alignment.

The Ski Pro device pairs a rigid carbon shell with a 55–65 Shore A EVA rearfoot post - delivering functional correction and rearfoot stability at a fraction of the weight of polypropylene. A 6mm semi-shallow heel cup controls inversion and eversion of the calcaneus and keeps the foot seated over the boot board.

A heel-to-toe Myolite extension and a proprietary Prolite top cover add shock absorption, insulation, and cushioning - so the device stays comfortable through 20 to 100+ days a season while holding the alignment that drives the edge.
