Maximum stabilization, across all three planes.
The UCBL is the best orthotic option for patients needing maximum stabilization. It is the most controlling foot orthotic option available and is commonly used by both children and adults with flexible flat-foot conditions.
A fully encompassing heel cup with medial and lateral flanges, combined with the custom-molded arch, locks the midfoot and rearfoot into a neutral position and prevents inversion, eversion, pronation, and other abnormal motion.
Walking and athletic shoes
An arch-length, high-volume shell that needs a roomy shoe with a removable sock liner.
Flexible flat foot
Commonly prescribed for children and adults with hypermobile mid and rearfoot and flexible flat-foot conditions.
Postoperative and severe pathology
Used where forefoot or rearfoot pathology needs the foot held, not simply supported.
Note: for a lower-profile shell that fits more footwear, the T5 Modified UCBL is recommended.
Maximum 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 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 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.
- UCBL frame fabricated: a Subortholene shell is vacuum formed over the positive model with a fully encompassing 18mm heel cup and medium medial and lateral flanges, finished with a thermocork rearfoot post and a .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 UCBL is set to the individual patient: shell rigidity, flange height, heel cup depth, and posting are all chosen for that patient's anatomy, degree of hypermobility, and footwear. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.
A Subortholene shell calibrated to patient 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, fully encompassing heel cup pressed from the patient's calcaneus, capturing the heel and controlling inversion and eversion.
A thin Protex top cover keeps the shell low-profile so the flanges stay comfortable inside the shoe.
Medium medial and lateral flanges rise around the midfoot, delivering 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 UCBL is the best orthotic option for patients needing maximum stabilization. It is the most controlling foot orthotic option available and is commonly used by both children and adults with flexible flat-foot conditions. This device features a fully encompassing heel cup with medial and lateral flanges to provide simultaneous control across the sagittal, coronal, and median planes.
When these flanges are combined with the custom-molded arch, the device locks the midfoot and rearfoot into a neutral position, preventing inversion, eversion, pronation, and other abnormal foot movements. Built with a positive model of the patient's foot and modifiable at the practitioner's discretion. For a lower-profile shell, see the T5 Modified UCBL.

Hold the foot, do not just support it.
A hypermobile mid and rearfoot collapses in more than one plane, so a plantar surface alone cannot control it. The UCBL adds vertical walls: medium medial and lateral flanges and a fully encompassing 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. The result is maximum stabilization, congruent to that patient's foot.
The right frame
for maximum control.
UCBL sits on the R4 UCBL frame profile: the extra-wide platform with deep heel capture,
the only frame with room for full medial and lateral flanges.
