Heel spur pain starts at the bone, not the shoe.
Every step concentrates force onto the plantar surface of the calcaneus. When a bony protuberance is present and the surrounding tissue becomes inflamed, that single point of contact becomes the source of every symptom. It won't resolve while the load is still concentrated there.
The root cause is mechanical — a bony deposit under direct load. Without offloading that specific point, rest alone cannot resolve the inflammation.
Concentrated plantar load
The calcaneal spur focuses ground reaction force to a single point with every heel strike — preventing inflamed tissue from recovering between steps.
Sustained inflammation cycle
Repeated mechanical irritation sustains the inflammatory response, making the spur progressively more painful with ordinary daily activity.
Chain-reaction dysfunction
Pain-driven gait compensation shifts load upward — placing abnormal stress on the Achilles, knee, and hip over time.
The P6 offloads the cause, not just the pain.
Custom-fabricated to your patient's exact foot shape with targeted horseshoe pad positioning.
Three interventions.
One precise solution.
The P6 doesn't mask pain — it offloads the mechanical source of it directly.
Horseshoe heel pad
A 3mm horseshoe-shaped pad precisely positioned to the calcaneal spur — directly offloads the protuberance rather than cushioning the entire heel generically.
Heel punch in frame
A depression in the polypropylene frame aligned with the spur location reinforces pressure redistribution — moving load away from the point of maximum tenderness across the rest of the foot.
Congruent shape
The custom-fabricated shell matches the patient's plantar surface precisely — distributing load across the correct structures, providing neurological feedback, and eliminating focal pressure at the spur site.
It's not just cushioning. It's targeted pressure redistribution.
The shape of what's under your foot determines how load is distributed across every structure during gait. A precisely congruent device with a targeted offloading system changes the pressure map — and changes the trajectory of tissue healing.
- Spur site offloading — the horseshoe pad and heel punch work together to redirect ground reaction force away from the calcaneal protuberance with every step.
- Neurological feedback — congruent shape provides continuous proprioceptive input throughout gait, improving muscle activation quality and reducing compensatory loading patterns.
- Muscle sequence in gait — hundreds of muscles fire differently based on what's under your foot. Root shape corrects this sequence, reducing the caloric demand and limping patterns that arise from heel spur pain.
- Distributed plantar load — volume congruency spreads pressure evenly across the plantar surface, eliminating the focal concentration that sustains inflammation at the spur site.
Shape is everything.
What separates Root from generic supports is the precise morphological shape captured from the patient's foot — held in the exact clinical position the clinician chose.
The Root orthotic matches the precise alignment the clinician held the foot in during scanning. This congruency offloads the spur site and redistributes load across the correct structures — ensuring the horseshoe pad lands exactly where it needs to.
Modern Root
Width adjusted considering both borders. Default for all Root models.
Traditional Root
Justified to the lateral border. Medial width reduced. Used for specific clinical indications.
Modern Root shape process
- Forefoot balanced to rearfoot — the forefoot-to-rearfoot relationship is optimised as the first step in shape modification.
- Fat pad expanded ~3mm — expanding the fat pad in the heel ensures the device fills the calcaneal contour precisely, positioning the horseshoe pad to the correct anatomy.
- 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 are both considered, 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 Achilles tendon vector?
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.
- 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, with the horseshoe pad positioned to the patient's specific spur location.

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 foot shape becomes a precision frame.
The journey from clinical capture to finished orthotic frame is where Root's expertise lives. Every step preserves the shape and position the clinician chose — ensuring the P6's horseshoe pad and heel punch land exactly where the patient's anatomy requires.
- Foot impression captured — the clinician captures the foot using their preferred method. The fashion in which the foot is held directly affects the outcome of the Root Shape congruency against the foot.
- Positive model created — the impression becomes a physical plaster model or a digital CAD/CAM model via FitFoot360. Digital models are stored indefinitely.
- Root technicians modify the shape — using FitFoot360, technicians apply the Modern Root shape process. The spur pad position is confirmed against the clinical prescription.
- Orthotic frame fabricated — the frame is vacuum formed over the positive model or 3D printed, pressing the material precisely to the shape. Covers, postings, and the horseshoe spur pad are then applied.

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 P6 is set to the individual patient — material, posting, spur pad position, and covers are all chosen for their anatomy and pathology, never an average.
Rigidity is selected per patient weight — so the shell provides consistent pressure redistribution away from the spur for that specific patient's load demands.
Extrinsic crepe post balanced forefoot to rearfoot — built into the positive model of the patient's foot. Provides rearfoot control while the heel pad manages spur offloading above.
Cast directly from the patient's calcaneus — the deep cup captures their heel precisely, positioning the horseshoe pad exactly where the spur requires offloading.
Trimmed to the patient's toe line, so contact and pressure distribution match their exact foot geometry.
Selected for shoe compatibility — keeps the device stable inside the shoe while the heel pad system delivers targeted offloading above.
Full-length cushioning that absorbs plantar impact without compromising the targeted heel offloading the device is designed to deliver.
Horseshoe-shaped and positioned to the patient's spur location — offloads the calcaneal protuberance directly, not generically.
What changes when the spur is genuinely offloaded.
Addressing heel spur syndrome biomechanically — rather than generically cushioning the entire heel — creates targeted improvements in pain, function, and tissue recovery.
- Immediate pressure relief — the horseshoe pad and heel punch offload the spur directly, reducing the sharp heel pain associated with first steps from day one.
- Faster tissue recovery — removing load from the inflamed tissue allows the inflammatory response to subside naturally, rather than being sustained with every step.
- Restored gait mechanics — pain-free heel contact normalises gait pattern, relieving compensatory strain in the Achilles, knee, and hip.
- Long-term prevention — structural offloading, not just cushioning, means significantly lower recurrence rates compared to generic insoles.
Designed to offload the spur. Protect the heel.
A horseshoe-shaped 3mm heel spur pad offloads the bony protuberance on the plantar surface of the calcaneus more effectively than traditional cushioning. Combined with a heel punch in the polypropylene frame, pressure is redistributed away from the spur across the rest of the foot. Fabricated from a positive model of the patient's foot, the P6 minimises mechanical stress at the point of greatest pain while maintaining full function throughout gait.

Heel Spur
A heel spur is a bony calcium deposit that forms on the plantar surface of the calcaneus — typically at the attachment of the plantar fascia or Achilles tendon. On its own, a spur is not always painful. When inflammation develops around the protuberance, every step concentrates load directly onto the deposit, producing acute, localized heel pain that worsens with activity.
When the Spur Becomes the Problem
Heel spurs develop gradually in response to chronic mechanical stress — repetitive pulling of the plantar fascia or Achilles tendon at its calcaneal insertion. The body lays down calcium to reinforce the attachment, and over time the deposit grows. When the surrounding soft tissue becomes inflamed, the spur transitions from an incidental finding to the primary source of pain.
Heel Spur Syndrome — Inflammation of the soft tissue surrounding a calcaneal spur. Presents as sharp, localized heel pain — worst with the first steps of the morning or after periods of rest, easing with movement then returning with prolonged activity.
Plantar Fasciitis with Heel Spur — Inflammation of the plantar fascia frequently co-exists with calcaneal spur formation at the fascial insertion. The spur amplifies mechanical irritation at the attachment site, intensifying symptoms and slowing recovery.
Insertional Heel Spur — Spur formation at the posterior calcaneus at the Achilles insertion. Associated with insertional Achilles tendinopathy and retrocalcaneal bursitis — often requiring combined offloading and heel lift intervention.
Diagnosis
Clinical assessment includes palpation of the plantar heel to localise pain and identify the point of maximum tenderness. X-ray confirms the presence and size of the calcaneal spur. Ultrasound and MRI are used to assess the degree of soft tissue inflammation and plantar fascia involvement when conservative treatment planning requires a clearer picture.
Treatment Pathway
First-line treatment includes orthotics, NSAIDs, rest, ice, and stretching of the plantar fascia and calf. Custom orthotics are most effective when introduced early — offloading the spur before chronic inflammation becomes resistant to conservative care. If little progress is seen at 2–3 months, corticosteroid injection or extracorporeal shockwave therapy is indicated. Surgical spur resection becomes a consideration after 6 months without meaningful recovery.
The P6 is designed to be part of the first-line response — offloading the calcaneal spur from the first step, reducing inflammation while the tissue heals.
