Understand how foot mechanics can influence comfort, movement and load.
Your feet influence everything above them.Start with the foundation.
Foot position and gait can influence how force moves through the ankles, knees, hips, pelvis and lower back. A focused assessment can help determine whether custom orthotics are a useful part of the wider plan.
Your feet can influence the whole movement chain.
Foot mechanics do not stop at the foot. Explore how load can travel through the ankle, knee, hip and lower back—and why the wider pattern matters.
Pressure, arch support, heel discomfort and how the foot meets the ground.
Why this matters: Orthotics are not automatically the answer. The purpose of assessment is to determine whether they fit your actual pattern.

Hips and movement considered together.
Orthotics are not simply shoe inserts
A custom orthotic is intended to support a specific biomechanical need identified through assessment. The useful question is not whether everyone should wear one. It is whether your foot mechanics, symptoms, footwear and activity demands make one appropriate for you.
Reasons people ask about orthotics
Foot or Heel Pain
Including patterns such as plantar fascia irritation or discomfort that changes with standing and walking.
Achilles or Ankle Strain
Recurring loading problems, instability or discomfort during walking, running or sport.
Knee Symptoms
Foot and lower-limb mechanics may influence how force is distributed through the knee.
Hip or Pelvic Compensation
Uneven mechanics can sometimes contribute to altered movement higher in the chain.
Lower-Back Loading
Foot and gait findings may be relevant when lower-back symptoms change with standing or walking.
Sport and Work Demands
Running, field sport and long hours on the feet can expose small mechanical issues repeatedly.
A useful orthotics process
History
Understand symptoms, footwear, work, sport and previous injuries.
Assessment
Review foot posture, gait, relevant joints and lower-limb mechanics.
Decision
Determine whether orthotics, footwear changes, exercises or another route makes sense.
Review
Check comfort, use and whether the support is helping the intended goal.
What orthotics cannot do
Orthotics are not a universal cure and should not replace appropriate medical assessment, rehabilitation or strength work. They are one possible tool inside a wider plan.

Clear answers before the next step
Are custom orthotics suitable for everyone?
No. Suitability depends on the symptoms, mechanics, footwear, activity and assessment findings.
What is the difference between custom and shop-bought insoles?
Custom orthotics are prescribed around individual findings, while retail insoles provide general cushioning or support.
Can orthotics help knee, hip or back symptoms?
Foot mechanics can influence loading higher in the body, but those symptoms can have many causes. Assessment is needed before assuming the feet are responsible.
Will I need to wear them all day?
Usage depends on the design, footwear, tolerance and intended goal. A gradual introduction may be recommended.
Can athletes use orthotics?
They may be useful for some athletes when a clear mechanical reason is identified and the device works with the sport and footwear.
Do orthotics replace exercises?
Not necessarily. Exercises, footwear changes, load management or other care may remain important.
How long do orthotics last?
Lifespan varies with materials, body weight, activity, footwear and wear. They should be reviewed if comfort or function changes.
How do I start?
Contact the clinic to confirm the appropriate assessment and appointment type.
