Road Cycling

Root Model: S16

Built for maximum watt efficiency. A rigid carbon-fiber frame transfers energy straight to the pedals, and a tightly contoured arch with minimal cast fill makes sure every ounce of effort is converted to watts. Developed with bike fitter Steven Carre.

Intended use

Built for maximum watt efficiency in the cleat.

The Road Cycling device is designed to enhance the power and efficiency of serious cyclists. Its low-profile design allows it to be fit to any cycling cleat.

A rigid carbon-fiber frame transfers energy to the pedals, minimising power loss from idle foot movement inside the shoe. A tightly contoured arch with minimal cast fill ensures every ounce of effort is converted to watts. Built congruent to the cyclist's own foot model, not an average.

01

Fits any cycling cleat

The low-profile build drops into road cycling shoes without raising the foot in a tight, stiff-soled upper.

02

No power lost to foot movement

The rigid carbon frame stops the idle foot movement inside the shoe that bleeds watts on every stroke.

03

Stays put in the shoe

A Myolite arch filler under the frame prevents the device from shifting in the cleat.

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 Road Cycling 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 rigid carbon frame and intrinsic post are fabricated to match the submitted shape precisely.

How closely each method preserves the patient’s intended foot shape. Scale: 0–100%, where 100% = optimal congruence.

From scan to finished orthotic

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

The journey from clinical capture to finished Road Cycling 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.
  • Road Cycling frame fabricated - the rigid carbon-fiber shell is formed over the positive model with a 6mm heel cup, an intrinsic rearfoot post, and a tightly contoured arch using minimal cast fill. A 15 Shore A Myolite arch filler and a 3mm Prolite top cover are applied, forefoot balanced to rearfoot. No bottom cover or extension.

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 Road Cycling device is set to the individual patient. Frame rigidity, heel cup depth, arch fill, and cover are chosen for that cyclist's anatomy, position, and cleat. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.

FRAME MATERIALRigid carbon

A rigid carbon-fiber frame, custom congruent to the foot model, transfers energy to the pedals with minimal deflection.

REARFOOT POSTIntrinsic

An intrinsic rearfoot post stabilizes the rearfoot congruent to the foot model without adding height inside the cleat.

HEEL CUP6mm

A shallow 6mm heel cup holds the calcaneus while keeping the profile low enough for a stiff-soled cycling shoe.

FRAME FILLER15 Shore A Myolite

A Myolite arch filler under the frame prevents the device from shifting inside the cleat.

ARCH CONTOURMinimal cast fill

A tightly contoured arch with minimal arch cast fill ensures that every ounce of effort is converted to watts.

TOP COVER3mm Prolite

A Prolite top cover from heel to toe for moisture control across long hours in the saddle.

BOTTOM COVERNone by design

No bottom cover or extension, keeping the device as low as possible against the shoe's footbed.

Biomechanics

Designed to turn effort into watts.

The Road Cycling device pairs a rigid carbon-fiber shell with an intrinsic rearfoot post and a shallow 6mm heel cup, holding the foot still so power goes into the pedal instead of into movement inside the shoe.

A tightly contoured arch with minimal cast fill puts the frame directly against the arch, while a Myolite filler underneath keeps the device from shifting in the cleat and a 3mm Prolite top cover manages moisture over long rides.
