Why shoe fit goes wrong: a fictional case study
Key takeaways
- Your usual shoe size is a starting point, not an answer. Width and volume matter as much as length.
- Construction decides how forgiving a shoe is: loafers and Oxfords leave little room, Derbies and laced boots leave more, and Chelsea boots leave almost none.
- A measurement only helps once you know how a specific model behaves on a foot like yours.
- Check the return policy before you buy, especially from overseas.
- Stretchers can ease tight toes, width and pressure points, once you’re close to the right size.
Finding the right shoe fit
Most shoe-buying mistakes aren’t obvious at first. The shoes feel fine in the shop, maybe even great, and it’s only after a few wears that something feels off. The heel moves. The toes crowd. A pressure point appears where you didn’t expect it.
Over time, those shoes drift to the back of the wardrobe, not because they’re badly made, but because they were never quite right for the foot they were bought for.
After more than a decade in the shoe industry, I’ve seen this play out countless times. The common thread isn’t poor quality or bad taste. It’s a shallow understanding of fit: not just size, but shape, construction, and how different shoes behave once you’re living in them.
This isn’t a sizing guide. It’s a fictional case study of how fit decisions change when you move from casual footwear to well-made dress shoes, especially when buying online.
A note on Bryan: he isn’t a real person. He’s a fictional character built from the sizing problems I’ve seen most often over the years, with the details invented to make each one easy to follow. The measurements, constructions and mistakes are all real patterns.
Meet Bryan
Bryan is a thirty-something IT specialist in Melbourne. He’s getting married in six months, work is going well, and he’s decided it’s time to sharpen up his wardrobe. After some research, he settles on two pairs of shoes to invest in, all well made, all meant to last for years.
- Goodyear-welted Oxfords for his wedding. The event is black tie, and he feels an Oxford suits the formality. He hasn’t chosen a maker yet.
- Crockett & Jones Boston loafers in calfskin, from the UK. Everything he’s read puts the brand among the best in ready-to-wear footwear, and he likes this model’s elegance and versatility.
Until now, Bryan’s footwear has been mostly casual: sneakers, weekend shoes, and a pair of Clarks Desert Boots. He buys a US 10.5 sneaker and owns the Desert Boots in a UK 9.5. There’s a little extra space at the toes, but nothing that’s ever really bothered him. With no obvious problems, he’s never questioned his sizing.
He comes to me for advice.
When your usual size stops being enough
On paper, Bryan hasn’t had many problems. The difference now is scale. He’s going from spending $100 to $150 on sneakers to spending up to $1,000 on a pair of shoes shipped from overseas. The margin for error shrinks fast at that level.
When I first started selling Goodyear-welted shoes, I was surprised by how many size returns we received. A pattern emerged. Many customers were using their US sneaker size or their R.M. Williams boot size to choose a UK dress shoe. Length might have been close, but width and volume were often wrong.
Before Bryan buys anything online, we need to understand his foot properly: not just how long it is, but how it’s shaped.
On the Brannock
We meet at a shoe store that carries several well-regarded brands rather than a single label. That matters. Independent stores tend to use a Brannock device set up to measure the foot itself, not one calibrated to a particular brand’s sizing.
I ask Bryan to come mid-afternoon, wearing the socks he’d normally wear with dress shoes. The timing is deliberate: feet swell slightly as the day goes on, which makes it a better moment to assess fit.

Bryan arrives having already spotted an Oxford on the store’s website that he’s keen to try. Then the Brannock changes what he thought he knew about his feet.
His longer foot measures a true UK 9. Not borderline, not a half size either way. Then we check width. His forefoot sits clearly in the wide range for that length, and he carries a little extra height through the midfoot. Together, those measurements explain why a half size up has always felt like his natural fit.

He wasn’t buying extra length because his feet were long. He was buying it to make room.
A quick note on width letters. Brannock devices use US letters, where D is medium and E is wide. UK makers use a different scale, usually F for standard, G for wide and H for extra wide, and R.M. Williams has its own, where G is standard and H is wide. The letters don’t convert one-to-one, and every maker draws the lines a little differently. Use your Brannock result to tell you whether you’re narrow, standard or wide, then check the maker’s own sizing chart before you order.
Different shoes suit different feet
Bryan tries the Oxford he’d picked out. Predictably, it doesn’t work. It feels tight across the forefoot and restrictive over the top of the foot.
The reason is construction. An Oxford has a closed-lace system, where the eyelet facings are stitched underneath the vamp. That leaves very little room for adjustment. On a wider foot with a higher instep, the shoe quickly feels constricting unless the fit is spot on.
The store assistant suggests an open-laced Derby in a wide fitting, still in a UK 9. The difference is immediate: same foot, same length, and now the shoe has somewhere to go. It sits comfortably across the forefoot, and the lacing lets the upper open slightly over the instep.

Wedding shoes sorted. Same foot, same UK 9: the construction made the difference.
A note on laceless boots
Everything above applies even more to boots with no laces. A Chelsea boot, such as the R.M. Williams Comfort Craftsman, is held on by one piece of leather and elastic side panels that let the foot in, then pull the boot closed around the ankle. That keeps the heel from lifting, so the boot has to be snug by design.
The elastic gives a little, but it can’t open up over the top of the foot the way laces can. A foot that is already wide and high, like Bryan’s, simply feels tight in a Chelsea, where the same foot has room to spare in a Derby.
My own boots show how this plays out. I measure a 10H in R.M. Williams, but I bought a 10.5G, and it fits well. On paper that looks contradictory. In practice, the extra half size gives my toes room, and the slightly narrower fitting keeps my heel and instep held securely, because there are no laces to do the job. Length, width and volume trade off against each other, and a half size in one direction can balance a step in the other. Before buying a laceless boot, read how that model fits people with feet like yours, and check the return policy.

Buying from England: to be or not to be
When it comes to the Crockett & Jones loafers, Bryan pauses. A loafer has no laces to adjust, so there is almost no margin for error. Returning a pair to the UK means postage both ways and weeks of waiting, with no guarantee the next size is right either. After weighing the risk, he buys them locally instead.

The upfront cost is higher, but the cost of getting it wrong is lower. In the shop he tries the same length in two fittings and picks the wider one. It’s a little snug for the first few wears, then eases as the leather moulds to his foot. It’s a good fit, not a perfect one, and he’s happy to accept that for a shoe with nothing to adjust.
Where each pair landed
- Derby (wedding): a genuinely good fit. Right size, right fitting, right construction.
- Loafers: a small compromise. Chosen deliberately, with a short break-in period.
What actually changes
By the end, nothing about Bryan’s feet had changed. What changed was the information he was working with, and how he used it.
The point isn’t that one brand runs large or another runs small. Shoe fit is shaped by more than a number on a box. Construction matters. Adjustability matters. Some shoes allow compromise; others don’t.
- A closed-lace Oxford demands precision.
- A laceless boot offers very little room to negotiate.
- A loafer leaves almost no margin for error.
Buying shoes online doesn’t have to be a gamble, but it does need context. Your measured size is a starting point. Knowing how a model behaves, how people with similar feet have fared, and what a wrong size will cost you often matters more than chasing the “correct” number.
Where shoe stretchers help, and where they don’t
A shoe stretcher is a shoe-shaped tool with a toe block and a heel block joined by a screw. Turn the handle and the blocks push the leather outward. Two-way models widen the shoe and add a little length, and small plugs let you target one spot, such as a bunion.
That is how it saves a shoe that fits too tight. Leather gives slowly, so a pinch on day one can take weeks of wear to ease. Under steady pressure, it gives in a day or two, and only where it’s pushed. A stretch across the forefoot could have eased Bryan’s first Oxford, though the Derby was the cleaner fix.
Stretchers can help with:
- Tight toes and a snug forefoot, including in boots. A toe-box stretcher adds room where it’s needed instead of stretching the whole boot.
- One pressure point, such as a bunion or the joint of the little toe. A spot-stretch plug targets just that area.
- Firm leather across the width or instep on a new Derby or loafer, which softens over a few sessions.
Stretchers can’t help with:
- A shoe that is well over a size too small. Most stretchers can add a little length, but the heel and toe cap are firm, so they can’t turn the wrong size into the right one.
- Heel slip, which stretching only makes worse.
To use one, spray the leather inside and out with a stretching spray or conditioner, set the stretcher snug rather than tight, and leave it in for 24 hours or more. If the shoe still pinches, turn it a little further and repeat.
We stock shoe stretchers and boot stretchers, plus spot-stretch plugs for targeted pressure points. Even with the right size, a perfect fit is never guaranteed. A stretcher lets you finish the job the way the shoemaker intended.
