Your arch is the messenger, not always the cause
A dropped arch rarely starts at the foot. It's often the last link in a chain that starts higher up — a hip that isn't controlling rotation, an ankle that doesn't bend the way it should, or years of shoes that never asked your foot muscles to do any work. That's why we test how the muscles from your hips down to your toes are actually functioning, not just look at your foot.
How we approach flat feet in Scarborough
- Assess. A full muscle function check, head to toe, to find out what's actually letting the arch drop — not a guess based on the arch alone.
- Correct. Daily foot and arch exercises, plus a footwear and orthotics strategy matched to your activity level — the plan below.
- Re-check. We re-test your muscle function and coordinate with your prescribing doctor to re-measure your orthotics, on a 3–6 month schedule set by how consistent you've been.
The debate we don't pick a side on
A lot of foot doctors lean hard toward custom orthotics and structured, supportive shoes. Some coaches and minimalist-shoe advocates lean the opposite way. The research says neither extreme wins on its own:
- Orthotics alone can weaken the exact muscles holding your arch up. In a 12-week trial, adults with flat feet who wore custom orthotics saw their arch-supporting foot muscles shrink 10–17% — with no gain in muscle activity to show for it (Protopapas & Perry, 2020, Clinical Biomechanics).
- Minimalist footwear rebuilds those same muscles. Eight weeks of walking in minimalist shoes increased foot muscle strength 41% (Ridge et al., 2019, Medicine & Science in Sports & Exercise); six months of daily minimal-footwear use raised it 57% (Curtis et al., 2021, Scientific Reports).
- But rushing into minimalist shoes backfires. Runners who switched over 10 weeks showed more bone stress injury than runners who didn't — the researchers' own advice was to go slower than that (Ridge et al., 2013, Medicine & Science in Sports & Exercise).
- Orthotics aren't useless, either. A systematic review of adult flatfoot studies found real, if modest, evidence they improve standing balance and reduce walking effort (Banwell et al., 2014, Journal of Foot and Ankle Research).
Used alone, both sides of this argument have a documented downside. Used together — split by surface, paired with daily exercise, introduced gradually — they cover for each other. That's the plan.
Can you graduate out of your orthotics?
Some people do, over time. Not everyone — it depends on which kind of flatfoot you actually have, and that's worth knowing no matter who you see.
Flexible flatfoot — your arch is there when your foot is off the ground, and flattens under weight — is the kind that responds to exercise. In one trial, six weeks of targeted exercise, three sessions a week, improved arch height and alignment significantly more than doing nothing (Brijwasi & Borkar, 2023, Journal of Physiotherapy). That's the mechanism behind reducing — sometimes eventually dropping — how much you rely on an orthotic.
What looks rigid isn't always rigid. A tight calf muscle can hold your foot flat and mimic true rigidity on a quick look. The real test: bend the knee and check the same movement again — if the ankle suddenly moves more freely, a tight calf was the limit, not your bones (FootEducation). That kind of tightness responds to stretching and corrective work over months, the same as a flexible arch does.
Truly rigid flatfoot — where a bone bridge between two foot bones (a tarsal coalition), an extra bone, or a joint that formed differently is genuinely holding things in place — won't change shape through exercise. But that doesn't mean you're done being checked. Your muscles, your weight and your activity level keep changing regardless of what your bones do, which is a real reason on its own to re-evaluate an orthotic over time (reassessment guidance generally recommends at least annual review, more often when your body changes). Nobody here gets a one-time verdict — everyone gets rechecked, and orthotics get adjusted, not fitted once and forgotten.
If you've been told flatly that you must wear rigid, supportive shoes forever with no room to ever test that, it's a fair question to ask which of these applies to you, and how that was determined. The evidence on orthoses for adult flexible flatfoot is genuinely mixed (see above) — a blanket rule isn't the same as an answer specific to your foot.
Your 3-part plan
- Daily corrective exercises. The only part of this that rebuilds arch strength — your foot's own stabilizing "core" muscles (McKeon et al., 2014, British Journal of Sports Medicine).
- Minimalist, flexible shoes on uneven ground — trails, grass, stairs — where surface variety trains the foot.
- Your orthotics on flat, repetitive ground — tile, pavement, long stretches — where there's no variety to train, only wear to manage.
Your exact split, and when we re-check your orthotics, gets set at your assessment and adjusted from there — based on your activity level and how consistent you are with the exercises, not a generic timeline.
How soon we re-check, based on your consistency
The honest 3–6 month range mentioned above isn't arbitrary — here's roughly how it breaks down.
Daily, or close to it — re-check at 3 months
One to two sessions a day, most days, for at least 6–8 weeks straight. This earns the earliest re-check.
Most days — re-check at 4–5 months
Four to six times a week, with the occasional missed day. Real progress, just slower to show up.
On and off — re-check at 6 months
A few times a week, or stretches of skipping entirely. Still worth a check-in on schedule — we don't push it further out than 6 months, even for inconsistent effort.
