How Custom Orthotics Work: Why Store-Bought Insoles Often Fall Short

Dr. Brad Pritchard • February 20, 2026

Foot pain rarely starts and ends in the foot. It can start in your knees halfway through a walk, creep into your hips after a long shift, or linger in your lower back at the end of the day.


Custom orthotics are designed around how your body moves to restore alignment at the source and reduce the chain reaction that travels up through your knees, hips, and lower back.


This article explains how they work, what sets them apart, and why customization shapes better outcomes than store-bought insoles.

What Are Custom Orthotics?

Custom orthotics are medical-grade inserts created specifically for your feet. They support and guide movement based on your structure and walking pattern.


At Oak Bay Chiro, the process begins with an assessment. Your
chiropractor evaluates how you stand and walk, and how your weight is distributed through your feet. They examine alignment, pressure points, and areas of strain. 


A detailed scan or impression captures the exact contours of your feet. We then craft your orthotics to match that shape and address the mechanical concerns affecting you. They fit inside your everyday shoes, influencing how your feet contact the ground with each step.


How Custom Orthotics Support Your Entire Body

Your feet form the base of your posture. When that base shifts, the effects travel upward.


If your arches collapse inward, your ankles roll. When your ankles roll, your knees rotate. That rotation affects hip alignment. Over time, your lower back compensates. Small imbalances compound with every step.


Custom orthotics help stabilize foot mechanics. They guide your feet into a more neutral position during walking and standing. This adjustment supports:


  • Ankles: Improved alignment reduces excessive rolling and strain.
  • Knees: Better foot positioning limits inward or outward knee stress.
  • Hips: Balanced lower alignment supports smoother hip movement.
  • Lower back: Reduced compensation eases tension across the lumbar spine.



Correcting foot mechanics often creates changes that extend beyond local discomfort. Movement feels steadier, long days feel more manageable, and recovery after activity feels faster.


Custom Orthotics vs Store-Bought Insoles

Store-bought insoles fill the shoe's interior, while custom orthotics guide movement.


Over-the-counter inserts come in standard shapes and sizes. They provide general cushioning and mild arch support. For occasional discomfort, they can offer short-term relief.


Custom orthotics focus on precision. They mold to your unique foot structure and address your biomechanical patterns. These details create targeted correction rather than broad padding.


Durability is another key difference. Store-bought insoles often compress quickly. As they flatten, their support decreases. Custom orthotics are made from higher-quality materials designed to maintain their structure over time.


Support level also varies. Generic inserts may soften impact. Custom devices actively influence alignment. They aim to address the root mechanical issue causing the pain.


For people with persistent discomfort, flat feet, high arches, or recurring strain, standard insoles may fall short. The symptoms may ease temporarily, yet the underlying pattern remains unchanged.


Who Benefits Most from Custom Orthotics?

If your discomfort returns with increased activity, if your shoes wear unevenly, or if your posture feels off balance, your feet may be contributing more than you realize. Custom orthotics can benefit a wide range of people:


  • Those with recurring foot, knee, hip, or lower back pain often find relief when their alignment improves
  • Active individuals and athletes who subject their bodies to repetitive stress
  • People who stand or walk for long hours and experience fatigue that builds throughout the day


Build Support From the Ground Up

Every step you take places force through your body. When your foundation lacks support, the strain travels upward. When your foundation aligns, movement feels steadier and more controlled.


At Oak Bay Chiro, we design custom orthotics in Calgary based on how you move. A personalized assessment can help determine whether tailored support could improve your day-to-day experience.
