Built for women's flats and moderate heels.
The Princess device is comparable to the Fashion device but better suited for women's shoes — flats to moderate heels with a consistent inclination angle. Its UCB-type, low-volume design delivers clinical support with minimal bulk, and can be modified with forefoot accommodations as needed.
Function without compromise. The Princess device brings congruent, custom support to women's fashion footwear — built from the patient's own foot model, not an average, and modifiable at the practitioner's discretion.
Women's flats to moderate heels
Best suited to women's shoes with a consistent inclination angle where a standard orthotic won't fit.
Comfortable worn sockless or in nylons
The suede top cover extends to the sulcus for soft, direct-to-skin wear without socks.
Low-volume fit
No extension material between the top and bottom covers keeps the device thin enough for close-fitting fashion shoes.
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 dress 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 Princess 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.
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 Princess 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.
- Princess frame fabricated — the polypropylene shell is vacuum formed over the positive model. Suede top cover extends to the sulcus and a suede bottom cover full wrap is applied, 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 Princess device is set to the individual patient — frame rigidity, rearfoot posting, heel cup depth, and covers are all chosen for that patient's anatomy and weight. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.
Calibrated per patient weight, so the low-profile shell delivers the control that patient's gait requires without adding bulk.
Intrinsic rearfoot post built into the shell — rearfoot control with the lowest possible volume for close-fitting women's shoes.
A shallow 6mm heel cup pressed from the patient's calcaneus — low-profile enough for dress footwear while still cradling the heel.
A clean functional shell with no filler — keeping the device low-profile so it seats correctly in fashion and dress shoes.
Suede top cover extends to the sulcus for comfortable wear without socks — a soft interface directly against the skin.
Suede bottom cover full wrap provides a soft interface in high-quality fashion shoes and protects the polypropylene shell.

Adequate control with minimal bulk.
The Princess device pairs a polypropylene frame calibrated to patient weight with an intrinsic rearfoot post — providing control of the subtalar and midtarsal joints while keeping the device at the lowest possible volume. The 6mm heel cup cradles the calcaneus and stabilizes the foot at the subtalar joint without adding volume that women's fashion footwear can't accommodate.
A suede top cover extends to the sulcus for comfortable wear without socks, and a suede bottom cover full wrap provides a soft interface — so the device performs and feels right in flats and moderate heels.
The right frame
for women's fashion feet.
Princess sits on the Dress frame profile — the lowest-volume Root frame,
tuned for women's flats and moderate heels without giving up clinical function.
