Hiker

Root Model: S22

Built for the trail. A polypropylene frame with an extrinsic 55-65 Shore A EVA heel post and a 12mm heel cup steadies the foot on uneven ground, while a 3mm myolite cushion and a full suede wrap absorb the load of a heavy pack.

Intended use

From day hikes to multi-month treks.

The Hiker device is designed to provide cushioning and support on outdoor treks ranging from day hikes to multi-month endeavors. A custom arch and extrinsic heel post improve balance and stability on uneven trails, built congruent to the patient's own foot model.

A pack changes the maths. A layer of myolite cushioning pads and protects the feet from the increased weight burden of additional gear and supplies, mile after mile.

01

Balance on uneven trails

A custom arch and an extrinsic 55-65 Shore A EVA heel post improve balance and stability underfoot, with a 12mm heel cup holding the heel steady.

02

Cushioning under load

A 3mm myolite device-length cushion provides shock absorption to pad and protect the feet from the weight of gear and supplies.

03

Wrapped in suede

The device is completely wrapped in suede to handle the abuse of carrying a 25-85 pound pack on overnight or extended expeditions.

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 sport 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 Hiker device 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.

Congruent Accuracy
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.

Impression Method (Clinician)

Plaster bandage is wrapped around the foot in the clinician’s prescribed corrected position, setting into a precise negative of the foot’s contour.

AdvantageYields an accurate, precise impression with easy foot alignment.
LimitationTime-consuming and messy to take.

From scan to finished orthotic

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

The journey from clinical capture to finished Hiker 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.
  • Hiker frame fabricated - the polypropylene shell is pressed over the positive model with a 12mm heel cup and an extrinsic 55-65 Shore A EVA rearfoot post, with no frame filler. A .6mm suede top cover, a 3mm myolite device-length cushion, and a .6mm suede bottom cover wrap the device completely, forefoot balanced to rearfoot.

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.

Biomechanics

Stability on trail, mile after mile.

The Hiker device pairs a polypropylene shell with an extrinsic 55-65 Shore A EVA rearfoot post and a 12mm heel cup. The custom arch and heel post together are what improve balance and stability when the ground stops being flat.

A 3mm myolite device-length cushion absorbs the shock of a loaded pack, and the full suede wrap keeps the device intact through overnight and extended expeditions.
