Intended use

Built for long hours and maximum cushioning.

The Cushion Plus delivers the functional, biomechanical support of a rigid-frame orthotic — the Pro Sport skeleton — then loads 6mm of Myolite padding for the soft, cushioned feel of an accommodative device. Ideal for patients who spend long hours on their feet, are sensitive to corrective orthotics, or have fat-pad atrophy.

Support and softness. A rigid functional frame carries 6mm of Myolite cushioning — built congruent to the patient's own foot model, not an average.

01

Extra-depth shoes with removable insoles

The ample cushioning takes up room in the shoe, so it seats best in footwear with a removable insole and extra depth.

02

Long hours on the feet

Maximum cushioning suits patients who stand or walk for long hours and want comfort without losing support.

03

Sensitive feet & fat-pad atrophy

Ideal for patients sensitive to the invasiveness of corrective orthotics, or with fat-pad atrophy needing extra padding.

FootID Pro scanning platform

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.

Generic support vs Root congruent shape
The Root difference

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 Cushion Plus 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.

Digital shape
Default ✓

Modern Root

Width adjusted considering both borders. Default for all Root models.

Cast in plaster

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 positions — neutral, pronated, supinated

*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.

FootID Pro — Clinical alignment scanning

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.

From scan to finished orthotic

How your patient's foot shape becomes a precision frame.

The journey from clinical capture to finished Cushion Plus 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.
  • Cushion Plus frame fabricated — the polypropylene Pro Sport skeleton is vacuum formed over the positive model, then loaded with 6mm of Myolite padding. A 3mm Spenco top cover, full-length Myolite extension, and suede bottom cover are applied with an extrinsic rearfoot post, forefoot balanced to rearfoot.

FitFoot360 Foot Model

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.

Construction

Built to their spec. Built for their foot.

Every parameter of the Cushion Plus is set to the individual patient — frame rigidity, rearfoot posting, heel cup depth, and covers are all chosen for that patient's anatomy, weight, and activity demands. Forefoot is balanced to rearfoot and the device is custom congruent to the foot model.

Design Device Overview

The Cushion Plus delivers the functional and biomechanical support of a rigid-frame orthotic, then adds 6mm of padding to simulate the comfortable, cushioned feel of an accommodative device. It is built on the Pro Sport skeleton and loaded with Myolite for a soft, maximum-cushioned feel.

Ideal for patients who spend long hours on their feet, are more sensitive to the invasiveness of corrective orthotics, or have fat-pad atrophy. Recommended for shoes with removable insoles, since the cushioning takes up room — and customizable to an intrinsic rearfoot post, metatarsal length, or thinner padding. Built from a positive model of the patient's foot and modifiable at the practitioner's discretion.

Biomechanics

Rigid-frame support with a cushioned feel.

The Cushion Plus pairs the rigid Pro Sport polypropylene frame with a 55–65 Shore A EVA extrinsic rearfoot post — full functional and biomechanical support beneath the padding. The 12mm heel cup controls inversion and eversion of the calcaneus, stabilizing the foot at the subtalar joint through the gait cycle.

Over that frame, 6mm of Myolite padding and a full-length extension simulate the soft, cushioned feel of an accommodative device — offloading sensitive feet and fat-pad atrophy while preserving the correction of a functional orthotic.
