Control
Root model: R3Our wide, high-control frame — maximum support and stability for work, therapeutic, and accommodative footwear.
R3 Control in the range.
R3 Control is the wide, high-control end of the Root range — maximum support and stability for work, therapeutic, and accommodative footwear. Every Root device shares the same custom capture of the patient's foot; the profile you choose sets how much volume and control the device carries.

What R3 builds into
The Control profile is the foundation for the Therapeutic device — the same wide, high-control base, tuned for accommodative and at-risk feet.
See it from every angle
Wide, full-contact, and built for work and therapeutic footwear — shown here in its standard configuration.
Start with R3, build the exact device
Every R3 Control device follows the same path — pick the frame material, set the rigidity, add covers and posting, then fine-tune with modifications.
Frame material
Choose the shell — durable polypro or low-profile carbon.
Rigidity
Set how much the frame flexes underfoot.
Covers & posting
Finish with top and bottom covers plus built-in posting.
Modify
Fine-tune with 845+ patient-specific modifications.
Frame options
Frame materials →A reliable, cost-effective polypropylene shell — the everyday workhorse frame that balances support and durability across most control prescriptions.
Learn more →A cushioned EVA frame that adds shock absorption and comfort — well suited to accommodative work and therapeutic wear.
Learn more →Thin, strong carbon engineered for a low profile — delivering full clinical support with minimal bulk in work and therapeutic footwear.
Learn more →A lightweight carbon frame with a responsive flex — a premium, energetic feel underfoot with minimal bulk.

Every parameter of the R3 Control is set to the individual patient — material, posting, heel-cup depth, undercut, and covers are all chosen for their anatomy and gait, never an average.
Rigidity is selected per patient weight — so the shell holds the correction exactly as much as that specific patient's structure and gait demand.
A 65 Shore A EVA extrinsic varus post added to control and stabilize subtalar joint motion — set to the patient's prescription, not a generic wedge.
A deep 18mm cup with a 20° device undercut cradles the calcaneus and maximizes rearfoot control for their specific degree of pronation.
The wide R3 frame, sized for work, therapeutic, and accommodative footwear so the device delivers full-contact support without crowding the shoe.
A 3mm Prolite cover run full-length to the toes, trimmed to the patient's foot geometry so contact and pressure distribution match exactly.
A vegan suede bottom cover finishes the shell so it sits quietly and securely inside work and therapeutic footwear.

Use the Root Library of Modifications to prescribe custom, patient-specific orthoses for optimal outcomes — postings, extensions, pads, and frame modifications, all on the R3 base.
Shape is everything.
What separates Root from generic supports is the precise morphological shape captured from the patient's foot — held in the exact clinical position the clinician chose.
The Root orthotic matches the precise alignment the clinician held the foot in during scanning. This congruency offloads strained structures and redistributes load across the correct ones.
Modern Root
Width adjusted considering both borders. Default across the Root range.
Traditional Root
Justified to the lateral border. Medial width reduced. Used for specific clinical indications.
Modern Root shape process
- Forefoot balanced to rearfoot — the forefoot-to-rearfoot relationship is optimised as the first step in shape modification.
- Fat pad expanded ~3mm — expanding the fat pad in the heel ensures the device fills the calcaneal contour precisely.
- 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 are both considered, giving a foundation that matches the patient's actual foot width.
*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.
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 Achilles tendon vector?
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.
- 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.

Variation converted to anatomy-match accuracy by impression & fabrication method
How closely each method preserves the patient’s intended foot shape. Scale: 0–100%, where 100% = optimal congruence.
Plaster bandage is wrapped around the foot in the clinician’s prescribed corrected position, setting into a precise negative of the foot’s contour.
The foot is pressed into a crushable foam box, leaving a negative impression of the plantar surface.
An existing positive model from the patient’s previous orthotics is reused — KevinRoot accepts models from any lab, with frame-contour variance as low as 1%.
A digital scanner such as FootID Pro captures the foot surface as a 3D model.
A fiberglass casting sock is applied over the foot and cures to capture its contour.
Pedobarography captures the patient’s plantar pressure distribution (static or dynamic) at 1:1 scale — used with arch height and shoe size to select a redimold positive model, not to capture true 3D contour.
A direct-molding system using prefabricated, size- and arch-based positive models (33 in total) rather than an individual foot impression.
Heated material is vacuum-pressed over a plaster positive model, drawing it intimately into every contour.
The frame is 3D printed by selective laser sintering (SLS) directly from the CAD-designed digital frame.
A positive model is CNC-milled (CAD/CAM) from an STS, 3D scan, plaster, or foam impression, then the frame is vacuum formed over it.
A CNC machine subtractively mills the frame from a block of polypropylene or EVA per the digital design.
*Redimold has no physical or digital foot impression — patient-foot-to-cast congruent accuracy is unavailable. Variation from positive model to frame is low.
How your foot shape becomes a precision frame.
The journey from clinical capture to finished orthotic frame is where Root's expertise lives. Every step preserves the shape and position the clinician chose.
- Foot impression captured — the clinician captures the foot using their preferred method. The fashion in which the foot is held directly affects the outcome of the Root Shape congruency against the foot.
- Positive model created — the impression becomes a physical plaster model or a digital CAD/CAM model via FitFoot360. Digital models are stored indefinitely.
- Root technicians modify the shape — using FitFoot360, technicians apply the Modern Root shape process. Every modification is reviewed against the clinical prescription.
- Orthotic frame fabricated — the frame is vacuum formed over the positive model or 3D printed, pressing the material precisely to the shape. Covers, postings, and modifications are then applied.
FitFoot360 Foot Model
- Root digital model stored indefinitely → recalled for future pairs
- Root technicians modify the digital shape in real-time: arch, heel, width, postings
- Vacuum formed over CAD/CAM positive model, direct milled or 3D printed Root Frame — replicable, consistent, precise
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.
