Complete Guide To Foot Orthotics


You may have many questions relating to foot orthotics and your foot condition. Please read on to learn about foot orthotics, their uses and what makes an Orthotics Plus foot orthosis different.

What are foot orthotics and when are they used?

Foot orthotics are devices which alter the biomechanics of your feet to correct, offload and/or support your feet to reduce pain, heal an injury and generally increase your quality of life.

Most of our patients present to us because of pain. If this is the case, the primary aim of the orthosis is to reduce pain and the success of the orthotic intervention is largely measured by this result.

Other patients present to us seeking to improve physical performance, heal an acute injury, make their day to day footwear feel more comfortable, or proactively prevent issues from occurring.

Foot orthotics can be custom made or pre-fabricated. The most suitable device will depend on your condition.

What are custom foot orthotics?

Custom foot orthotics are bespoke devices made specifically for your foot and your condition. This means they will be tailored exactly to you and not created based on a generic template.

We are able to customise the foot orthotic to suit your footwear, lifestyle and presentation depending on the outcome of the assessment we provide. Foot orthotics can be broken into 3 sections and the options available at each segment can be used in combination. The design and features used will depend on your assessment and what we are aiming to achieve.

Here are some common features of a foot orthotic.

Hindfoot
Heel cupping, selective offloading (ie for heel spurs), wedging, height increase (to alter ankle pitch or accommodate for a leg length discrepancy)

Midfoot
Selective offloading (ie plantar fascia grooves), medial arch support, arch control, lateral arch support, transverse arch support

Forefoot
Forefoot wedging, metatarsal domes, selective offloading, metatarsal cut outs, hallux cut outs

The density of the material we use for the device will also vary according to height, weight, age, activity and clinical presentation.

How do foot orthotics work?

The human foot is made up of 26 bones, 33 joints and over one hundred tendons, ligaments and muscles. This structure is remarkable in its function, however things do go wrong. The result may be acute pain, inefficient biomechanics, stress injuries, chronic issues or bad posture of the foot leading to ankle, knee, hip and back pain amongst other problems.

If we provide support and correction to the foot, we can address many issues by protecting or reducing load on the stressed tissues. By supporting the bony structures of the foot we can offload tired overworked muscles and encourage the activation of other muscles which may not be as active due to the malalignment.

Foot orthotics will not magically heal your issue, only your body can do that, but we will encourage an environment which will make this possible. Most patients do notice immediate pain relief when wearing their foot orthotics.

Everything is connected! For example, a flat foot which overly pronates (rolls inwards) may suffer from aching arches and lateral (outside) ankle impingements locally, but the flow on effect internally rotates the tibia, causes the knees to dip inwards (valgus malalignment) and the pelvis to drop. The gluteal muscles are then required to work harder to prevent internal rotation and adduction at the femur which could aggravate lower back pain.

Some patients with knee osteoarthritis find foot orthotics and suitable footwear will reduce some pain in their knees as the ground reaction force is shifted to the less damaged region of their knee.

Foot orthotics are best used in conjunction with suitable footwear, which your orthotist can advise you on.

Do I need foot orthotics?

The answer to this question is generally based on these factors:

Pain - If you have a high level of lower limb and foot pain, your pain is worsening, or your foot pain has been persisting for a longer time we may be more inclined to suggest foot orthotics. If your foot pain is low and reducing then we may suggest other options first.

Age - If you are younger and growing, or older and not healing as well or the pain is limiting your mobility foot orthotics may be required.

Biomechanics - An assessment of the structure and function of your foot will assist this decision. If during the assessment and gait analysis we note issues we can immediately address, foot orthotics may be a good option for you. (e.g. hyper mobility, flat feet, very high arched feet, pronated foot posture, bony prominences, painful rigid joints, osteoarthritis, foot structures which cause torsional forces in the foot).

History -What have you done previously? Have you tried other options or changed your footwear recently? Have you recently started training for a marathon? Are you noticing your feet change shape? The answers to these questions will assist us to determine a course of action. If there are things we can modify in your life such as activity level we will advise accordingly.

Diagnosed conditions- If you have a particular condition which we know responds well to foot orthotics we will be more inclined to suggest foot orthotics as a treatment.

What is the comfort guarantee?

We will ensure your foot orthotics are comfortable. We offer unlimited appointments for 3 months after fitting to solve any fitting and comfort issues. Our orthotists can adjust the devices on the spot without the orthotics being sent away, so it will not require excess appointments or long wait times to fix issues.

If it is required they are remade due to an error on our behalf, there will be no charge for this.

What are some common conditions ?

  • Pes planovalgus (painful flat feet)
  • Pes cavus (rigid high arched feet)
  • Osteoarthritis
  • Rheumatoid arthritis
  • Plantar fasciitis
  • Achilles tendinopathy
  • Stress fractures
  • Metatarsalgia
  • Ankle pain and impingement
  • Midfoot collapse
  • Diabetic ulcers
  • Lateral column overload
  • Medial column overload
  • Shin splints

What shoes can you wear with foot orthotics?

Custom made foot orthotics can be fit into most shoes. We have made foot orthotics to suit business/dress shoes, women’s fashion shoes, football boots, running shoes and flats.

Having said that, we will generally advise a style of shoe without a high heel and some structure to the shoe. We understand that for the shoes and foot orthotics to be worn they must suit your lifestyle and looks are important to most people. This can all be discussed in the appointment and factored into our shoe selection advice.

We do keep a limited range of shoes in stock for trial and purchase at our Melbourne foot orthotic clinics.

What is the Orthotics Plus Difference?


We never use hard plastics! We manufacture our foot orthotics from EVA (Ethyl Viny Acetate). This shock absorbing material is much more comfortable for the foot whilst still allowing excellent support and control to be built into the orthotic.

The properties of EVA allow us to make small modifications during your fitting appointments to completely tailor the foot orthotics to your footwear and your feet. Most other clinics choose to use plastic as it is cheaper and more easily able to be made at a central fabrication clinic.

We manufacture all custom foot orthotics on site and use the highest quality EVA materials. It is more time consuming to manufacture foot orthotics this way however the results are superior in comfort and function.

We will never leave you with a pair of uncomfortable and intolerable foot orthotics. We can modify them during fitting and during your free follow up period to ensure they are comfortable and functional.

How do I get started?


We will start by asking you about your history and lifestyle, progressing to a thorough assessment of the foot, ankle, knee and hip and some gentle palpation of the affected/painful areas.

Measurements may be taken at this point, particularly joint angles.

We will then conduct a full gait analysis and report in plain terms our assessment and findings and begin to formulate our prescription.

Based on the assessment, we will capture a physical or digital impression of your foot. For particularly troublesome feet we will manipulate the foot into a corrected position and take a physical impression and sometimes even cast the feet in the position we need using plaster.

We will create either a plaster or digital representation of your foot and modify accordingly. This is dependent on the assessment but usually involves increasing the arch height, correcting the hindfoot, offloading any prominent or painful areas and generally correcting the biomechanics of the foot to resolve the issue you presented with. This is done by a tertiary educated professional orthotist who has studied in depth, lower limb anatomy and biomechanics.

Our orthotics are made in Orthotics Plus’ onsite workshop laboratory. Unlike the vast majority of podiatry groups in Australia, we will never outsource our custom foot orthotics to be made by a central fabrication group. The clinician who assessed your foot will be the clinician who creates your orthoses.

We use high density EVA in our orthotics. This material is more expensive than plastic, increasing our cost of manufacture and the time required, but it has excellent properties which lend to foot orthotics perfectly.

The EVA is either milled by our carving machine into the design created by the orthotist or heated and vacuum formed over the cast in multiple layers to capture the shape required.

The foot orthotic is then hand finished by the orthotist to fit your shoe and comfortably correct and support your foot.

After the fitting has been deemed successful, we will generally cover the device with a material (usually fabric, leather or synthetic) for hygiene and aesthetic purposes.

It’s time to get the right foot support

Why do we make orthotics with EVA and not plastic?


We don’t believe in hard plastic foot orthotics for the reasons below:

Plastic reduces mobility

The foot is a mobile structure with many joints and the body’s primary shock absorber. We don’t want to take away the mobility of the foot as we are likely to create other problems higher up the chain. Using a dense foam/EVA allows the foot to continue to be a shock absorber whilst correcting biomechanics.

Plastic orthotics are painful

Many patients find them to be unforgiving and painful, requiring a long wearing in period and can be the cause of many issues. We regularly see patients in our clinic with previously made hard plastic foot orthotics complaining of bruises and even blood blisters from stepping on the sharp heel cup of the plastic foot orthotics.

Plastic is difficult to modify

Hard plastic foot orthotics are difficult to modify by the clinician during the appointment. This may lead to the incorrect prescription or an uncomfortable device being encouraged to be kept as the re-manufacturing process is time consuming and potentially expensive.

Plastic will wear quickly

The covers of hard plastic foot orthotics generally wear very quickly as they are guillotined between the foot and a hard plastic shell. Even when topped with foam for softness, we find this material disintegrates within a few months, requiring repair or most commonly the patient just ends up walking on a hard plastic base with no cover.

We are yet to see a patient prefer a hard plastic foot orthotic over an Orthotics Plus EVA device

Reasons for the continuing popularity of plastic foot orthotics is they are cheaper and easier to produce and are often made ‘en masse’ at a central location by machine.

At Orthotics Plus we use varying densities of foam EVA as this allows the foot to be supported, while providing the comfortable relieving shock absorbing values most suited. Many of our older patients need a soft EVA, while our heavier and more athletic patients use a higher density material.

As we don’t outsource to external technicians or manufacturing hubs we can modify the foot orthotics on the spot and customise it to you. This means we can fit the orthotic in nearly all shoes and modify the device without the need for multiple annoying trial and error style appointments.

FAQ's for Foot Orthotics


Please see below for some other frequently asked questions, if you would like further clarification or can’t find your answer then please call our friendly team.

What if I don’t find them comfortable?

It’s normal for foot orthotics to require a wearing in period and there to be some discomfort.

This discomfort is generally muscular as patterns are broken and different (often neglected) muscle groups are used. There may also be some light skin rubbing as areas which were previously non-weightbearing take load and the tissue adapts. This is normal. This usually resolves in a short time frame and many people forget they’re even wearing them.

For the cases when issues do not resolve quickly, we will offer unlimited (within reason!) appointments in the following 3 months after prescription until the foot orthotics are deemed satisfactory to you.

Will foot orthotics weaken my feet?

No. This is a common myth. When used correctly foot orthotics do not ‘take over’ the role of muscles in your feet, leaving them lazy and ineffective. They correct a biomechanical issue and rebalance and normalise the muscle activity in your feet. Many studies and even a systematic review have found a more normalised muscle activity in patients with a flat foot deformity when using foot orthotics.

When aligned correctly the foot will work more efficiently as the muscles and joints are not at the extreme end range of their possible range of motion. Muscles generally work more efficiently and can produce more strength during the middle of the range of motion of the respective joint they control.

Additionally a foot which has a corrected posture will provide a better and efficient structure for human gait during running, walking or sports.

Many elite athletes wear foot orthotics and we regularly see athletes to assist with their chosen sports.

Are foot orthotics the entire answer?

Foot orthotics may be a piece of the puzzle but are rarely the entire solution. We will discuss all the other factors which have contributed to the pain or issue and advise as such.

This may be better selection of footwear, behavioural modifications and lifestyle modifications just to name a few.

We may also prescribe a lower limb stretching and strengthening regime where indicated to assist with the orthotic management and support your recovery, particularly in the case of plantar fasciitis.

When required we will refer you to a specialist if it is outside of our scope of practice. i.e. dietary advice or surgical intervention.

How long will my orthotics last?

The structure of our foot orthotics will last almost indefinitely, the shape may begin to change after a couple of years though, so we suggest a review appointment if you feel like you require more support or things have changed. Top covers which are primarily aesthetic and used for hygiene tend to wear out more quickly and we can re-cover them for you in one 10-15 minute appointment.

What is the comfort guarantee?

We will ensure your foot orthotics are comfortable. We offer unlimited appointments for 3 months after fitting to solve any issues. Our orthotists can adjust the devices on the spot without the orthotics being sent away, so it will not require excess appointments or long wait times to fix issues.

If it is required they are remade, there will be no charge for this

How much do foot orthotics cost?

For all initial appointments we charge a $70 consultation, where we can openly discuss what is required and the costs involved prior to committing to purchasing orthotics.

The cost for your initial pair of custom made foot orthotics is $590. This includes the following:

  • Scanning and modifying
  • Fabricating
  • Fitting
  • Reviews for up to 3 months

If you would like a second pair of foot orthotics identical to your first for convenience or to suit other shoes, they are $390.

If you are uncertain as to whether we can assist with your foot condition, we would recommend coming in for the initial consultation to discuss.

For kids who are growing and changing regularly, we have some “off-the-shelf” options that are more affordable considering they will need to be replaced more regularly.

Orthotics Plus - Case Studies


Case Study 1

John

Age

53

John (an active 53 year old male) visited Orthotics Plus for a second opinion about his newly made hard plastic foot orthoses. His newly purchased and rather expensive orthotics weren’t providing him any pain relief from his lateral ankle impingement and pain down the lateral (outside) aspect of his foot, despite multiple follow up appointments.

Our orthotists conducted an assessment and a full gait analysis. On observation it was noted he had a normal hindfoot posture on heel strike with a varus forefoot posture. From heel strike to foot flat the lateral aspect of his foot would strike the ground first and his 1st metatarsal was elevated. As his weight was accepted by the forefoot, his midfoot would rotate to allow his forefoot to reach the ground which would cause his hindfoot to violently evert (resulting in a valgus calcaneus> causing his lateral ankle impingement) to allow the more medial aspect of his forefoot and finally 1st metatarsal to eventually make contact with the ground until toe off, when the process would start again.

The hard plastic foot orthotics were little more than an arch support which in this case was not the prescription needed. John’s predominant issue was a varus forefoot, led by a dropped 5th metatarsal and an elevated 1st metatarsal.

Orthotics Plus manufactured a custom foot orthosis which cushioned the hindfoot and cradled the heel, supported the arch during foot flat, restored the midfoot transverse arch and using a forefoot wedge and 5th ray cut out controlled the forefoot to prevent the rotative force driven through the foot as the 5th metatarsal made contact with the ground. We also offloaded the metatarsal heads. John had previously been suggested to wear a strong pronation control shoe. We strongly suggested a neutral soled shoe to avoid extra stress being placed through the lateral forefoot.

John’s lateral ankle pain was resolved very quickly and on review 2 weeks later the pain in his lateral foot had also resolved. John felt he was able to run for longer periods and felt like his gait was more efficient with less internal rotation transmitting up his tibia into his knees.

Case Study 2

Judy

Age

75

Judy (a moderately active 75 year old female) presented to the clinic with generalised midfoot pain (Right>Left), a hot ache down the medial right ankle and a feeling of instability on her right side. She felt like her feet has started to change shape. She had never worn foot orthotics before and presented to the clinic wearing flat unsupportive footwear.

Our orthotists conducted a full assessment and gait analysis. It was noted that the right medial longitudinal arch collapsed more during transition to foot flat and toe off than the left side. Judy was unable to perform a single leg heel raise on her right side but was able to do so partially on her left side.
Judy also felt that when she was walking unshod on hard surfaces or with unsupportive shoes it felt like she was ‘walking on marbles’.

It was concluded that Judy was experiencing tibialis posterior tendon dysfunction, bilaterally with the right side worse than the left. Secondarily the loculated fat padding underneath her metatarsal heads had diminished which caused her sensation of ‘walking on marbles’.

A mould was taken of her feet in the corrected position of subtalar neutral with the great toe extended to engage the windlass mechanism of the plantar aponeurosis and induce as much arch as possible. In a fantastic display of customer service, our orthotist then went to the shoe shop with Judy and her daughter to help select a pair of shoes which would be suitable.

During modifications the arch height did not need to be increased as this was captured during the impression. The foot orthotics were made of dual density EVA so the arch and hindfoot would experience as much support as possible while the forefoot bony prominences would be comfortably padded. A gentle metatarsal dome was added to help alleviate the forefoot pressures.

Judy had reduced pain in her right midfoot and medial ankle when wearing the foot orthotics and felt she had reduced symptoms related to a feeling of instability. It was explained to Judy the progression of the foot deformity can be treated and slowed or ceased with correct prescription of foot orthotics and selection of footwear and a correct wearing regime.

Case Study 3

Luke

Age

28

Luke (an active 28 year old male weighing approx. 105kgs and working as an electrician) presented to the clinic due to persistent arch pain and general foot soreness after playing football or working on his feet all day. He had never worn foot orthotics before but had tried purchasing insoles from the Chemist. He presented wearing flat casual shoes but said he generally wore lace up work boots.

The clinician performed a full gait analysis and assessment. On observation it was noted Luke had extremely flat feet (pes planovalgus) and was experiencing hyper-pronation.

The foot was passively corrected into a position with an increased arch height via manual manipulation and an impression was taken of both feet.

During the modification process Luke’s medial arch height was increased further, and an inbuilt metatarsal dome to offload the forefoot was added.

Due to Luke’s high activity level and weight, a higher density EVA was selected. Hindfoot medial wedging was added to attempt to straighten the hindfoot.

On fitting the foot orthotic was customised to suit his football boots and workboots. It was strongly suggested that a more supportive pair of casual shoes were sourced which had a better structure and more support.

On review Luke was extremely happy with the results. He was able to work a full day on his feet without the arch pain and felt much less discomfort in his feet. After a wearing in period he was able to play out a full game of football without pain and felt that his balance and ability to run and change direction more quickly was improved. He stated that he felt like he would run and stand ‘flat footed’ prior to fitting and felt more ‘dynamic’ when wearing the foot orthotics.
