Control while the foot is still growing.
The Pediatric UCBL is designed for children ages 3 to 16 with reducible foot deformities, or for those who would benefit from a device that provides biomechanical control across all three planes of movement.
In many cases the change in foot architecture instigated by the device is maintained even after the device is no longer used or needed.
Athletic and sport-specific shoes
Ideal for athletic footwear, and built with materials designed to withstand perspiration.
Children ages 3 to 16
Sized and posted for growing feet with reducible deformity and hypermobile mid and rearfoot.
Toe walking and outoeing
Also used for toe walking, outoeing, and moderate to severe forefoot or rearfoot pathology.
Note: for adults needing the same level of control, the T4 UCBL is recommended.
Pediatric control, 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 Pediatric UCBL 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 Subortholene shell, flanges, and thermocork rearfoot 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 Pediatric UCBL 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.
- Pediatric UCBL frame fabricated: a Subortholene shell is vacuum formed over the positive model with a deep 18mm heel cup and high medial and lateral flanges, finished with a thermocork rearfoot post and a durable .75mm Protex top cover, 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 Pediatric UCBL is set to the individual child: shell rigidity, flange height, heel cup depth, and posting are all chosen for that child's anatomy, age, and activity. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.
A Subortholene shell calibrated to the child's weight, rigid enough to hold the foot rather than follow it.
No frame filler. The shell and flanges do the work, with nothing soft between the foot and the correction.
A thermocork rearfoot post sets the frontal-plane correction and takes the edge off ground contact.
A deep heel cup pressed from the child's calcaneus, capturing the heel and controlling inversion and eversion.
A durable vinyl Protex top cover, chosen to withstand perspiration in active children.
High medial and lateral flanges deliver rigid support and simultaneous control in the sagittal, coronal, and median planes.
No forefoot extension. The device runs to the metatarsals, keeping the shell arch-length.
No bottom cover. The Subortholene shell seats directly in the shoe.
The full picture.

Guide the architecture while it is still forming.
A hypermobile pediatric foot collapses in more than one plane, so a plantar surface alone cannot control it. The Pediatric UCBL adds vertical walls: high medial and lateral flanges and a deep heel cup grip the foot above the level of the sole, resisting eversion, abduction, and midfoot collapse together.
The thermocork rearfoot post sets the frontal-plane correction, and the 18mm heel cup captures the calcaneus so the subtalar joint stays where the clinician put it through the gait cycle. Because the skeleton is still developing, the corrected architecture is often retained after the device is outgrown.
The right frame
for growing feet.
Pediatric UCBL sits on the R4 UCBL frame profile: the extra-wide platform with deep heel capture,
scaled to a child's foot and the shoes they actually wear.
