High control that still fits the shoe.
The Modified UCBL is designed to be a more versatile variation of the classic UCBL device. With a lower heel cup and full-length padded extension, it is a great option for patients who need high control in active applications.
A high lateral flange and medial flange without the encompassing, restrictive heel cup: moderate control across all three planes, compatible with a wide assortment of shoe types.
Walking and athletic shoes
A full-length build with a padded extension that seats in most footwear with a removable sock liner.
Moderate to severe overpronation
Its progressive design controls moderate to severe overpronation and other biomechanical pathologies.
Active applications
High control for patients who are on their feet and cannot give up shoe options to get it.
Note: for maximum stabilization with a fully encompassing heel cup, the T4 UCBL is recommended.
Moderate 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 Modified 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 polypropylene 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 Modified 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.
- Modified UCBL frame fabricated: a polypropylene shell is vacuum formed over the positive model with a 12mm heel cup and medium medial and lateral flanges, finished with a thermocork rearfoot post, .75mm Protex top cover, 3mm Myolite extension, and suede bottom 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 Modified UCBL is set to the individual patient: shell rigidity, flange height, heel cup depth, posting, and extension are all chosen for that patient's anatomy, degree of pronation, and footwear. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.
A polypropylene shell calibrated to patient weight, delivering high control in a lower-profile build.
No frame filler. The shell and flanges carry the correction, with cushioning added above instead.
A thermocork rearfoot post sets the frontal-plane correction and takes the edge off ground contact.
A lower 12mm heel cup pressed from the patient's calcaneus: control without the encompassing, restrictive wall of the classic UCBL.
A thin Protex top cover keeps the shell low-profile so the flanges stay comfortable inside the shoe.
A high lateral flange and medial flange give moderate control in the sagittal, coronal, and median planes while keeping the device shoe-friendly.
A full-length padded Myolite extension carries cushioning through to the toes.
A suede bottom cover seats the device quietly in the shoe from heel to toe.

Three-plane control, without giving up the shoe.
A hypermobile mid and rearfoot collapses in more than one plane, so a plantar surface alone cannot control it. The Modified UCBL keeps the vertical walls that matter, a high lateral flange and a medial flange, and drops the encompassing heel wall, so the foot is still resisted in the coronal and transverse planes with far less bulk.
The thermocork rearfoot post sets the frontal-plane correction and the 12mm heel cup holds the calcaneus, while the 3mm Myolite extension keeps the forefoot comfortable through propulsion. The result is high control the patient will actually wear, congruent to their foot.
The right frame
for low-profile control.
Modified UCBL sits on the R4 UCBL frame profile: the extra-wide platform with deep heel capture,
here built with a lower heel cup so it fits a wider assortment of shoes.
