Pain through the arch of the foot is commonly associated with the plantar fascia, but not all arch pain is plantar fasciitis. Pain around the inside of the midfoot, particularly near the navicular bone, can also involve the tibialis posterior tendon. Assessment is used to identify the painful structure and investigate the mechanical loading patterns contributing to the condition.

The arch contains several structures capable of producing pain. Establishing exactly where the symptoms are located and which tissue is painful is an important part of the assessment.
One of the most common causes is plantar fasciitis. Although plantar fasciitis is frequently associated with pain underneath the heel, the plantar fascia extends forward from the heel through the arch. Symptoms can therefore be felt further along the fascia within the medial arch of the foot.
Another important consideration is the tibialis posterior tendon. This tendon passes behind the inside of the ankle and continues towards the navicular region of the midfoot. Irritation around this area can produce pain through the inside of the arch that may initially appear similar to plantar fascia pain.
The precise location of symptoms and the way pain responds to loading can help distinguish between different structures within the arch.
The plantar fascia runs from the heel towards the front of the foot. Pain may be concentrated underneath the heel, but it can also extend forward along the medial arch.
Symptoms may be noticeable during the first few steps after rest, when walking barefoot on hard surfaces, or following increased periods of standing, walking or activity.
The tibialis posterior tendon travels around the inside of the ankle before attaching predominantly around the navicular region of the midfoot.
Pain associated with this tendon may be felt around the medial mid-arch or navicular region and can increase when the tendon is placed under greater mechanical demand.
Arch pain can present differently depending on the structure involved and the mechanical environment surrounding the foot.
Pain may follow the inside of the arch from the heel towards the midfoot, particularly when the plantar fascia is involved.
More localised discomfort around the navicular and medial midfoot may indicate involvement of the tibialis posterior tendon or its insertion.
Plantar fascia pain can be noticeable during the first few steps after getting out of bed or following a period of rest.
Longer periods of walking or standing can increase cumulative loading through the plantar fascia and supporting structures of the arch.
Running, gym activity and sport can increase demand through the arch, particularly when combined with changes in footwear or training exposure.
Hard floors and unsupportive footwear can increase symptoms in some presentations by changing the mechanical environment beneath the foot.
Pain can continue when the affected structure remains exposed to repeated mechanical stress. This may occur during walking, standing, exercise or simply through the footwear being used throughout the day.
The important question is therefore not only where the foot hurts, but what continues to load the painful structure.
Several factors can act simultaneously. Assessment considers the mechanical environment surrounding the painful structure rather than examining each factor in isolation.
Cushioning, heel height, midsole geometry, forefoot stiffness and overall shoe structure can alter loading through the plantar fascia and medial arch. Different shoes can expose the same foot to very different mechanical conditions.
Calf restriction and ankle function can influence the way the body progresses over the foot during walking and running, changing mechanical demand through the arch.
Rearfoot movement, midfoot mobility, arch behaviour and side-to-side asymmetry can influence the forces transferred through the plantar fascia and tibialis posterior tendon.
Changes in running distance, walking volume, gym activity or sport can increase tissue demand. The cumulative weekly load is often more relevant than a single exercise session.
Long periods on the feet, hard flooring and occupational footwear can create repeated loading through the arch even when there has been no obvious change in exercise.
Symptoms can persist when the painful tissue is repeatedly reloaded before it has had sufficient opportunity to recover. Identifying the continuing source of mechanical irritation is therefore important.
Treatment begins by determining which structure is producing the symptoms. Plantar fascia pain and tibialis posterior tendon pain can occur within a relatively small anatomical region but require different clinical considerations.
Once the painful structure has been identified, biomechanical investigation considers why that structure is being exposed to excessive or persistent load.
Sydney Heel Pain Clinic has treated more than 7,000 patients. Our clinical work includes plantar fascia conditions and mechanical foot pain extending beyond the heel into the arch and midfoot.
Arch pain requires accurate localisation before treatment begins. The objective is to establish which structure is painful, identify the loading patterns surrounding that structure and determine which changes are required to create a better environment for recovery.
Treatment is selected according to the structure involved and the mechanical findings identified during assessment.
Footwear is assessed according to the condition and the individual foot. Cushioning, heel height, midsole geometry, stiffness and overall shoe design can all influence loading through the arch.
Calf and lower-limb management is selected according to the functional findings. The objective is to address relevant restriction or loading patterns without unnecessarily increasing stress through the painful structure.
Temporary modifications may be used to alter load through the plantar fascia or medial arch while symptoms settle and the mechanical environment is being addressed.
Running, walking, gym activity and occupational exposure are considered together. Where required, loading can be temporarily modified without automatically removing all activity.
Shockwave therapy may be considered in selected chronic plantar fascia presentations. Its use depends on the diagnosis, duration of symptoms and the mechanical environment surrounding the painful tissue.
Where foot mechanics are contributing to persistent loading, custom orthoses may be used to modify forces through the painful structure. Devices are modelled using CAD and 3D printed in-house, allowing orthotic geometry and design parameters to be matched to the individual foot.
Plantar fasciitis is a common cause of pain through the medial arch because the plantar fascia extends from the heel towards the front of the foot. However, the location of the pain should be assessed rather than assuming that all arch pain involves the plantar fascia.
Yes. Plantar fascia symptoms are not always confined to the heel. Pain can occur further forward along the plantar fascia within the medial arch.
Pain around the medial navicular region can involve several structures. One important consideration is the tibialis posterior tendon, which has a major attachment around this region of the midfoot.
Yes. Footwear changes the mechanical environment beneath the foot. Cushioning, heel height, stiffness and shoe geometry can alter demand through both the plantar fascia and the supporting structures of the medial arch.
No. Orthoses are considered when the mechanical findings indicate that modifying foot function may reduce persistent loading through the painful structure. Treatment depends on the individual presentation.
No GP referral is required for a private podiatry appointment. Patients attending under an eligible Medicare referral plan will require the appropriate GP documentation.
Appointments are available at Sydney CBD, Miranda, Crows Nest and Parramatta. Bring several pairs of frequently worn shoes to the appointment where possible.
