Built to correct Cavo-varus supination.
The Coleman is designed for the Cavo-varus deformity — where the hindfoot is flexible and returns to neutral when a Coleman block is placed under the lateral foot. It carefully corrects supination resulting from a rigid plantar-flexed 1st ray, using a lateral wedge and valgus rearfoot post to bring the foot into neutral alignment.
Correction by design. A 4-degree lateral wedge, valgus rearfoot post, 1st ray cutout, and reverse Morton's extension work together to balance first met head pressure — built congruent to the patient's own foot model, not an average.

Rigid plantar-flexed 1st ray
Corrects supination driven by a rigid plantar-flexed 1st ray, balancing first met head pressure.
Rigid Cavo-varus architecture
For a flexible hindfoot that returns to neutral under a lateral Coleman block — the device holds that correction.
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.
Shape is everything.
What separates Root from generic 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 Coleman 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.
Modern Root
Width adjusted considering both borders. Default for all Root models.
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 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 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.

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 patient's foot shape becomes a precision frame.
The journey from clinical capture to finished Coleman 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.
- Coleman frame fabricated — the polypropylene frame is vacuum formed over the positive model with a 4-degree lateral wedge, VG lateral frame filler, and 1st ray cutout. A Protex top cover, reverse Morton's extension, and suede bottom cover are applied with a 4-degree valgus oblique rearfoot post, forefoot balanced to rearfoot.
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.
Built to their spec. Built for their foot.
Every parameter of the Coleman 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 activity demands. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.
A polypropylene frame calibrated to patient weight — a rigid, supportive platform to hold the Cavo-varus correction through gait.
A valgus lateral frame filler adds a 4-degree lateral wedge from heel to metatarsals — carefully correcting supination toward neutral.
A 4-degree valgus extrinsic oblique rearfoot post accompanies the lateral wedge to ensure neutral alignment of the foot.
Pressed directly from the patient's calcaneus, the heel cup fits their heel precisely — controlling their specific degree of inversion and eversion.
Low-profile Protex top cover keeps the device slim so it seats cleanly in athletic and walking footwear.
A reverse Morton's extension offloads the 1st metatarsal head, working with the 1st ray cutout to balance first met head pressure.
Suede bottom cover protects the polypropylene frame and seats cleanly on the shoe's footbed across shoe environments.

Lateral posting that corrects supination.
The Coleman pairs a weight-calibrated polypropylene frame with a 4-degree lateral wedge from heel to metatarsals and a 4-degree valgus extrinsic oblique rearfoot post — carefully correcting Cavo-varus supination and bringing the flexible hindfoot to neutral. The 12mm heel cup controls inversion and eversion of the calcaneus at the subtalar joint through the gait cycle.
A 1st ray cutout and reverse Morton's extension offload the rigid plantar-flexed 1st ray to balance first met head pressure, while a Protex top cover keeps the device comfortable underfoot.
