Your shoes are the only piece of equipment you use roughly 8,000 to 10,000 times a day. Every step presses a little more of your movement pattern into the foam and rubber.
That makes them one of the most honest pieces of evidence you own. A physiotherapist, a chiropractor and I would all look at a worn shoe and see the same thing: a record of how that person has been loading their body, for months.
Grab the shoes you wear most. This takes about two minutes.
The width test
Stand up, with your weight fully on your feet. Look straight down at your shoe.
Your foot widens when you stand on it — and widens more when you walk. If the shoe looks the same width as your foot, or narrower, it's squeezing your forefoot with every step.
What you want: the shoe should look very slightly wider than your foot at its widest point.
Years of a too-narrow toe box is one of the ordinary, boring contributors to bunions, and tight shoes are a known risk for a pinched nerve between the toes (Morton's neuroma). Not the only cause — but a daily one.
The heel hold test
Put the shoes on and lace them the way you normally do. Now try to slide a finger down behind your heel, between your heel and the back of the shoe.
Pass: your finger doesn't really fit. The heel is held.
Fail: your finger slides in easily.
If your heel is loose, it moves inside the shoe on every step. The heel has a built-in fat pad designed to absorb impact — but it only works when the heel is actually seated. A sloppy heel means your foot spends all day doing extra work just to stay stable.
Often this is a lacing problem, not a shoe problem. Before you replace them, lace all the way to the top hole. In a study of 20 runners, lacing up to the top eyelet locked the foot into the shoe better and lowered pressure under the heel. My tip: use elastic laces. They hold your heel in place without squeezing your ankle, so it can still bend freely. Regular laces pulled tight at the top can restrict it.
Flat inside?
Take the shoe off. Run your hand along the inside, from the heel to the toes.
Pass: it feels close to flat.
Clue: it slopes down from the heel to the toes.
A raised heel keeps your calf a little shortened all day. In one study, women who had worn high heels for at least two years had calf muscle fibres about 13% shorter than women who wore flat shoes.
Most running shoes, dress shoes and work boots have some slope. If you switch to flatter shoes, switch slowly — your calves need time to adjust. More on choosing shoes.
Left vs right — the one that surprises people
Put both shoes on a flat table. Crouch down so they're at eye level, and look at them from behind.
Ask:
- Do both heels sit straight up, or does one tilt inward or outward?
- Is one more worn down on the outside edge?
- Do the two toe boxes look like the same shape?
Here's the part people don't expect: this is worth checking on brand-new shoes too. A left and right shoe don't always match straight out of the box.
If your two shoes aren't the same, your two legs aren't getting the same deal — about ten thousand times a day.
The wear map
Flip both shoes over and compare the soles side by side. You're not looking for wear — wear is normal. You're looking for differences between left and right.
- One heel more worn down than the other
- More wear under one big toe
- One toe box scuffed at the very front
- Deeper creasing across the top of one shoe
Then look inside the shoes, at the insoles. Friction marks show up there first, and they're often more uneven than the soles.
Bonus: the twist test
Hold the heel in one hand and the toe in the other, and gently twist them in opposite directions, like wringing a towel. Then try to fold the shoe in half, toe to heel.
A shoe with life left in it resists you, and springs back.
A dead shoe twists easily, folds in half, and stays bent. The upper can still look fine while the sole underneath has stopped doing its job.
Now here's the part that matters most.
Most people find uneven wear and buy new shoes. That feels like solving it. It isn't.
The shoes didn't create the pattern — they recorded it. New shoes wipe the evidence without changing what caused it. If the cause is still there, the same pattern often comes back, in the same places, within a few months.
Uneven wear often means something further up the chain — a foot, an ankle, a hip, an old injury you've stopped thinking about — is making one side work differently than the other.
What to do with what you found
If everything passed: good. Re-check every few months — and once a shoe fails the twist test, it's done.
If you failed the width, heel-hold or flat-inside checks, or the twist test: that's usually a shoe problem, and a new, properly fitted pair genuinely helps.
If you failed the left-vs-right check or found uneven wear: that's not a shoe problem. That's your body's movement pattern showing up in rubber, and buying new shoes will not change it.

One honest limitation: this checklist can tell you that something is uneven. It cannot tell you why. Uneven wear under the right big toe could come from the foot, the hip, the pelvis, an old ankle sprain, or how you sit at work. Those are different problems with different fixes — and guessing wrong wastes months.
Want to know which one it is?
That's what your free first visit is for. We test how each major joint is working — foot, ankle, knee, hip, back — to look for what's driving the pattern. If it's a fit, the full 90-minute assessment builds your plan to correct it, and we re-test to show whether it's working.
Bring the shoes you wear most. Genuinely — they tell me a lot before you say a word.
