Your feet carry your entire body weight — every step, every day. When something isn’t working properly in the foot’s biomechanical structure, the effects ripple upward through the ankles, knees, hips, and lower back. Often, people manage these symptoms with painkillers, activity avoidance, or store-bought insoles — without ever addressing the underlying foot mechanics.
Custom orthotics — medical insoles prescribed and fabricated specifically for your foot structure — can correct these mechanics and provide relief for a surprising range of conditions. But how do you know if you actually need them?
Here are 7 signs that it may be time for a custom orthotic assessment at Rishaan Physio & Wellness Clinic in Mississauga.
SIGN 1: YOU HAVE CHRONIC HEEL PAIN OR PLANTAR FASCIITIS
If your first steps in the morning feel like walking on broken glass — intense heel pain that gradually eases as you walk around — you are likely experiencing plantar fasciitis. This is the most common cause of heel pain in adults, affecting approximately 10% of people during their lifetime.
Plantar fasciitis is almost always driven by abnormal foot mechanics — most commonly overpronation (the foot rolling inward excessively), which places repetitive excessive tension on the plantar fascia. Custom orthotics that control rearfoot pronation and provide a dedicated plantar fascia off-loading groove are one of the most effective conservative treatments available.
Multiple systematic reviews confirm that custom orthotics are significantly more effective than prefabricated insoles for plantar fasciitis.
SIGN 2: YOUR SHOES WEAR UNEVENLY
Turn your shoes over and look at the wear pattern on the soles. Normal wear is moderate and relatively even, concentrated at the heel and ball of the foot.
Heavy wear on the inner heel and ball = overpronation (flat foot mechanics)
Heavy wear on the outer edge = supination / underpronation
Uneven wear is a visible sign of biomechanical abnormality. Without correction, this uneven loading is transmitted to your joints — particularly the knees, hips, and lower back — increasing wear and the risk of injury.
SIGN 3: YOU HAVE PERSISTENT KNEE PAIN (ESPECIALLY RUNNER’S KNEE)
Patellofemoral pain syndrome (PFPS), commonly called “runner’s knee,” causes pain around or behind the kneecap — particularly with stairs, squatting, or prolonged sitting. It’s extremely common in runners, hikers, and people who stand for long hours.
The connection to your feet: overpronation causes the tibia (shin bone) to rotate inward, which in turn causes the kneecap to track abnormally, creating friction and pain. Custom orthotics that correct rearfoot mechanics reduce this abnormal tibial rotation and significantly decrease PFPS symptoms.
Research published in the British Journal of Sports Medicine demonstrates that custom orthotics significantly outperform flat insoles and stretching alone for patellofemoral pain.
SIGN 4: YOU HAVE LOWER BACK PAIN WITH NO CLEAR SPINAL CAUSE
Lower back pain that has persisted despite physiotherapy, massage, and spinal treatment — and has no clear disc, joint, or nerve cause identified on imaging — may have a biomechanical foot/leg origin.
A leg length discrepancy of as little as 6mm creates pelvic tilt, lumbar scoliosis, and compensatory muscle patterns that manifest as lower back pain. Overpronation of one foot can functionally shorten that leg, mimicking a structural length discrepancy.
If your physiotherapist identifies this pattern, a custom orthotic with a heel lift can correct the discrepancy and resolve the resulting lumbar symptoms.
SIGN 5: YOU HAVE FOOT PAIN DURING OR AFTER STANDING FOR LONG PERIODS
If your feet ache, throb, or feel fatigued after a day of standing — in a profession requiring prolonged time on your feet (healthcare, retail, hospitality, construction) — your feet are absorbing forces that your foot structure is not adequately equipped to distribute.
Custom orthotics redistribute pressure across the entire plantar surface of the foot, reducing localised overloading of the metatarsals, heel, or arch. Many patients in these professions find that custom orthotics eliminate foot fatigue and pain almost entirely.
SIGN 6: YOU HAVE FLAT FEET OR VERY HIGH ARCHES
FLAT FEET (Pes Planus)
Flat feet (absent or collapsed arch) are a common finding in both children and adults. Not all flat feet are symptomatic — but when they are associated with pain, fatigue, or instability, custom orthotics provide structural support that cannot be replicated by standard footwear.
HIGH ARCHES (Pes Cavus)
Feet with very high arches have rigid structures that absorb shock poorly, concentrating impact on the heel and ball of the foot. This predisposes to stress fractures, plantar fasciitis, Achilles tendinopathy, and ankle instability. Custom orthotics with appropriate cushioning and lateral posting address the specific biomechanics of a cavus foot — something store-bought cushioning insoles cannot adequately do.
SIGN 7: YOU’VE HAD MULTIPLE ANKLE SPRAINS OR ANKLE INSTABILITY
Recurrent ankle sprains suggest chronic lateral ankle instability — ligament laxity on the outer side of the ankle that predisposes the joint to rolling. While physiotherapy for ankle strengthening and proprioception training is the primary treatment, custom orthotics that post the lateral heel and improve rearfoot alignment reduce the tendency for the ankle to roll, providing an external stability supplement.
If you’ve sprained the same ankle more than once, a combined approach of physiotherapy and custom orthotics is strongly recommended.
WHAT HAPPENS AT A CUSTOM ORTHOTIC ASSESSMENT?
At Rishaan Physio in Mississauga, a custom orthotic assessment takes approximately 45 minutes and includes:
– Full lower limb biomechanical assessment (foot structure, ankle mobility, knee alignment, hip mechanics, gait analysis)
– Identification of the specific biomechanical dysfunction driving your symptoms
– Discussion of the type of orthotic most appropriate for your condition, footwear, and activity level
– Foot casting or 3D scanning
– Prescription and laboratory order
Orthotics typically arrive within 2–3 weeks. At the fitting appointment, your physiotherapist ensures correct fit, explains the break-in protocol, and assesses your gait with the devices in place.
INSURANCE COVERAGE IN ONTARIO
Most extended health insurance plans in Ontario include custom orthotic coverage of $200–$500 per year. At Rishaan Physio, we provide all required documentation (biomechanical assessment report, prescription) for your insurance claim and offer direct billing where available.
FREQUENTLY ASKED QUESTIONS
Q: Do I really need custom orthotics or will store-bought insoles work?
A: It depends on your specific condition and biomechanics. If you have significant structural foot abnormalities, a diagnosed condition like plantar fasciitis or PFPS, or multiple failed attempts with OTC insoles, custom orthotics are very likely to provide superior results. A professional assessment is the only way to know for certain.
Q: How long until I feel a difference with custom orthotics?
A: Most patients feel improvement within 2–6 weeks of consistent use. A break-in period is normal — start wearing orthotics for 1–2 hours per day and gradually increase use over 1–2 weeks.
Q: Will custom orthotics weaken my feet?
A: No — this is a common misconception. Custom orthotics are used alongside a strengthening program, not as a replacement for it. They correct position while exercises build the strength to maintain that position over time.
Q: Do orthotics go in any type of shoe?
A: Custom orthotics can typically be transferred between shoes of similar types. Running shoes, walking shoes, and casual shoes with removable insoles accommodate most orthotics. Dress shoes and very flat shoes may require slimmer orthotic designs.0
