Flat Feet and Overpronation: What’s Actually Going On
Your arches ache by mid-morning. Your shoes wear thin along the inside edge before the rest of the sole shows any wear at all. Maybe your knees or hips have started chiming in too. If any of this sounds familiar, you may be dealing with flat feet, overpronation, or both, and we can help you find out what's actually happening, and what we do about it at Kootenay Pedorthic Clinic.
Flat Feet and Overpronation Aren't the Same Thing
Flat feet describes shape, it's how much arch height you have (or don't) when you're standing still and during your gait. Some people are built this way from childhood and never have a single problem with it.
Overpronation describes movement, how far your foot rolls inward as it strikes the ground and moves through your stride. A certain amount of inward roll is normal; it's part of how your foot absorbs shock. Overpronation is when that roll goes further than your foot and lower leg can comfortably manage.
The two often travel together, but not always. We see patients with a flatter-looking arch whose gait is perfectly efficient, and patients with a normal or high arch who overpronate significantly on the move. That's part of why a proper assessment looks at how you walk, not just how your foot looks parked on the exam table.
Why It Develops
Genetics play a significant role, foot structure, ligament laxity, and arch height are largely inherited, and for a lot of people that's simply the shape they were built with.
Footwear and activity history matter too, where years in unsupportive shoes, high-mileage running, or jobs that keep you on hard flooring all day can accelerate changes in how your foot functions.
Life changes can shift things as well, such as pregnancy, weight changes, and the natural loosening of ligaments and tendons with age are all common drivers of a foot becoming flatter or a gait becoming more pronated over time, even in people whose feet were never flat before.
Signs It's Worth Getting Looked At
Flat feet and overpronation aren't automatically a problem as plenty of people carry both without a day of pain. It's worth booking an assessment when you notice:
Pain or fatigue in the arch, heel, or ankle — especially if it builds over the course of a day on your feet, or lingers after activity.
Uneven shoe wear along the inside edge — a clear sign your foot is rolling further inward than it should through your stride.
Knee, hip, or lower back discomfort that tracks with time spent standing or walking — overpronation changes how load travels up the leg, and that can show up well above the foot.
A visible change in your arch over recent months — particularly worth flagging if it's come on gradually rather than something you've always had.
How We Assess and Treat It at Kootenay Pedorthic Clinic
A proper assessment goes beyond looking at your foot standing still. We look at your gait, how your weight distributes through each step, and the wear pattern on your own footwear — all of which tells us how your foot is actually functioning day to day.
From there, treatment depends on what's driving your symptoms. That might mean footwear guidance, activity modifications, or custom-casted orthotics built specifically to support your arch and control excess pronation through your stride. Some patients need a full custom orthotic; others do well with targeted footwear changes alone. There's no single fix that applies to everyone.
Book an Assessment
Flat feet and overpronation are common, and for most people, they're simply part of how their body is built. But when pain, uneven wear, or a changing arch start showing up, it's worth having it properly assessed rather than guessing at the cause.
We see patients from Nelson, Castlegar, Trail, Kaslo, and throughout the Slocan Valley for exactly this kind of concern — if it sounds like you, book an assessment and we'll get to the bottom of it together.
